NO ROOT REQUIRED - Volume Booster - Fire General

This will be a short and simple thread. I have a Fire HD 8 and HD 7, with the 7 being rooted. In my opinion, they lack a few notches in the volume control. I have found it incredibly difficult to find an app or Xposed module that would actually boost the volume of the Fire tablets, with or without root...until today.
On my rooted HD 7, I have Xposed installed along with the Gravity Box module, which has a volume boosting option, however it doesn't work. I've tried many apps on both devices, to no avail. However I had recalled an app I used on my phone before I rooted it, and just remembered it today.
Introducing 'Volume Booster by GOODEV'. It's simple, easy and takes up virtually no space at all (less than 1MB). I just installed it so I can't speak for battery consumption as of yet. There are only a few settings, all of which are pretty self explained. It also forces a notification to remain in the statusbar so the system doesn't shut it down. This option can also be disabled or set to appear in the statusbar only when active. You can increase the volume as much as 40% above the maximum level. The app is 100% free, but does contain ads (images below have ads cropped out).
I've found it to echo a bit on the HD 7, but works perfectly on the HD 8 once you calibrate it. Setting it to above 8% will cause a bit of static for some sounds.
**Warning**: I am NOT responsible for any damage done to your device or your hearing. Use at your OWN risk. Please be very careful using this app. It can potentially cause hearing damage when using headphones, or even permanently damage your speakers. I recommend a setting no higher than 7 or 8% above maximum, but please test it at lower levels until you're satisfied.

This is a nice option for those seeking to boost (amplify) the output volume of their device. Gravity Box, Volume Steps and similar Xposed modules simply increase the granularity of volume steps without increasing maximum output levels.
Another option is to flash a different audio package such as Dolby ATM or Viper4 which both refine and amplify output. This works wonderfully on HDX devices that arguably have the best audio capabilities of any Amazon tablet. However, such embellishments come with some risks including bootloops if not compatible with the underlying hardware/firmware. I would only suggest tinkering with such options with older bootloaders that support custom recoveries.
Which brings the discussion back to Volume Booster which works on any ROM rooted or not. Nice find, @DragonFire1024

Thanks this had come across my recommendations and had looked at my library on the Play Store and there it was. I was quite surprised it worked on my HD 8. It's probably the simplest of the ones I've tried over the times. Sometimes when we search for things like this, we often forget that sometimes the simplest of applications work better than the ones we really want and can't use.
I would love to use Viper. It's an amazing tool that has pretty much any feature you can imagine. I used Viper4Android on my XT907 for a time, but as that device is passing it's prime, my Bluetooth would just cease to function after a few uses. It really made all the difference in sound quality. I would love to be able to use it again.

Lol Dragonfire, came to see what you had found here. Same one I've been using for months lol. It is the only one I've found that actually works too. I made a thread one time about the fire tablet 7 5th gen sound being bad. Low and "tinny" sounding. That is a great volume booster but I don't set the boost past 20%. Boost the volume great but for me, I also have to use Equalizer FX to put a bass tone in the voices when I use ear buds. My Google Play review requested to add a basic equalizer to the volume booster guy just to throw that out there so I do not use two apps, which sucks, but I doubt he will. Also, I see no ads in this app, but I do use Adguard.

Adguard is nice and that's probably why you don't see them. If you made that thread in the past several months, I seem to recall it and was looking for it prior to making this thread. I will have to agree there are more times than not when the HD 7 does sound lower than it should be. It really is a shame the Gravity Box booster doesn't work on it though. Now the only thing I use GB for is to fix the recent apps button (the square button) which has a hissy fit when you 'uninstall' Fire Launcher, even on rooted tablets.
TESTS: So Far, after watching a few shows using VLC Player, I have NOT noticed any significant difference in battery consumption which is actually a big plus. In regards to the echoing on the HD 7, Just adjust the setting to not go above 8-10% of maximum. That stops the echoing for pretty much all sounds (I noticed the most echoing when locking or unlocking the screen). I am going to take a gamble and say the speaker system is different in the devices, when comparing it to the HD 8. Whereas you get a slight echo on the HD 7 if turned up past 8-10% (depending on your setup [I think I will try yours with a bass boost Captain]), you get a second or less of static on louder sounds on the HD 8, but not with all sounds. When receiving calls with Hangouts, the sound seems perfect when a bit past 10, but when you get a message using Google Voice, there is a bit of static with that sound.

You can try installing via FlashFire recognizing a bootloop or other failure will will require a reload of FireOS 5.3.1, reroot (and KingRoot battle) followed by restoring a recent backup via FlashFire. Obviously network isolation is a must while on FireOS as any OTA update will yield an unrootable device.

GravityBox is *NOT* a volume booster! It is working as designed to increase the granularity of various audio output controls which I find very beneficial. One can not fault an app/module for something it was not designed to do. As for non-audio features/tweaks there is much to like about GravityBox. It just might take you awhile to find and appreciate them. Some other modules worth exploring: AppOpsXposed (if on Nexus), InstallerOpt and Xposed Edge. The latter is like GravityBox on steroids but has a fairly steep learning curve for more advanced functionality. Enjoy!

Edge is pretty nice. I use it on my XT907. I managed to install ApOpps on my fire 7. When I say install I mean actually install. I used the APK my XT907 used. I added a few permissions and it worked perfectly. I know GB isn't a volume booster, but it does has the tweaks to add volume levels/notches, but the HD 7 refuses to acknowledge it. TBH I don't know why. GB is still awesome. And I still recommend it.
I just might try to flash Viper. I'm still debating if I want to flash Nexus or not. I get nervous with doing these type of things as I'm very inexperienced at doing so. Most of my work on my devices has been scripts or other modifications that are less of a risk.
EDIT: I added the ACCESS_SUPERUSER permission to AppOpps APK which is what I think did the trick at getting it to a fully operational state. TBH though, I don't know. Again as with some of the experiments I've done, I wasn't expecting to work at all.

I have an original Amazon Fire 7 from 2015 with the 5.0.x BL on it. I'm going to have to give Xposed a go on this device as I'm now running the Lineage ROM with security backports from @ggow and it is pretty awesome. I have always thought the volume on the device was a little low even at its max so this might just do the trick.

Please stop disseminating this misinformation. GravityBox does not have a "volume booster" setting. You have mischaracterised it as such despite no internal documentation suggesting this capability. What it does feature is a setting that enables additional increments within the existing volume range. That works just fine for media playback. There are other Xposed modules that can add granularity to other system sounds such as ringer and notifications

My mistake. You are correct and without looking at the app, that's what I was trying to get at, without sounding stupid. Clearly I should have looked at it again and my apologies for not doing so. I wasn't trying misinform anyone. That being said, I never tried it on media playback on the HD 7, but I have in my phone and yes I do recall it works in media playback and used it for playing my music via Bluetooth at work. So again I do apologize for coming off like that.

All good - thanks for following up. Enjoy the balance of your day.
[BTW - VolumeSteps+ is one module that offers similar flexibility with other system sounds (ringer, notifications, etc). As I recall there are seven (!) unique sound categories in Android, although not all devices support all output types. One downside to increasing granularity is the time it takes going from min to max volume via physical button as the system still pauses momentarily at each level when long pressing.]

Indeed there are 7. And you're also correct in the output. At least Amazon added quite a bit of different tones. But if you aren't using their software, you don't get access to them. I notice this while setting the alarm. There are a dozen or so. Ringtones should pop up in Media Storage, accessible using Activity Launcher or through Nova Launcher activities, however in my case only the Hangouts tone exists. I still haven't experimented with other ringtone/notification tone apps. That's on the list though.
Here's a question: termux is very cool. I know the devices have the ability to vibrate, there are hints in various places on the HD 8 at least that suggest it. Termux has the ability to make things vibrate. I just can't get the plugins installed properly. Cordova is installed via Termux, but I can't figure out how to install the plugin. Everytime I try is says the directory doesn't contain a project or isn't correct. Termux creates the proper directory and paths. Where do I put it and what am I doing wrong? (Just a general question to whomever).

I have no experience with Termux; agreed it looks very cool (added to personal bucket list). I don't believe the Fire 7 (and presumably HD 8) have the physical hardware to vibrate. Something Amazon has omitted from most, if not all, Fire devices. You are the expert in the room on Termux/Cordova as my knowledge could be written on the back of a postage stamp and still have room for the Lord's Prayer. Hopefully someone else chimes in.

Let me rephrase, because in a technical sense it's not really "vibration". Haptic feedback would be a more correct term? Supposedly FireOS does support Cordova (also here on NPM) and if I am reading correctly, the feature as well, unless they don't update their site often. Termux-API also supports it. I also don't get an error when I input the command in Termux. *scratches head.*
In my opinion, not even enabling a little bit of vibration is a bit odd. Even on other tablet like devices and phones there's always some kind of low level haptic when the volume is at the lowest. Older model Kindle Fires allegedly supported it.
Termux supposedly has the ability to do a good many cool things, but I have read over a few of the things and I got a bit confused. Studying what you can do with it takes some time and a lot of reading.
EDIT: I just tried one of the commands listed above in Termux API: termux-contact-list. Worked like a charm. Listed every contact. Crazy.

Same hardware component provides both types of tactile feedback. It's either there or not. The speaker in these little gizmos doesn't hit the low frequencies needed to emulate such feedback.

i would guess for cost savings this thing doesn't have the ability to vibrate, but termux is a fun app if you want to do some scripting on your tablet.

SOFT BRICK OR STUCK in a BOOTLOOP? REVERT TO STOCK
TWRP is required to use the following backup. Please make sure you still have it installed and are able to access it.
Download the stock OS backup Here http://www.4shared.com/zip/dxnYQfmpba/stock_zgpax.html
You need to be able to access your SD Card, if not you may need to use an external SD. Navigate to /SD Card/TWRP/Backup (or create the folder if it doesn't exist). Next you need to make a folder called Stock ZGPAX. Then your are going to place the files you downloaded here from the link above.
IF you cannot access your SD Card, try using an external MicroSD card. You will have to make the /TWRP/Backup Directory and Folder yourself... and then place the files in there manually.
Finally, you will REBOOT into TWRP and Navigate to the restore option. Look for your folder there and restore this backup.

SMS & INCOMING CALL NOTIFICATIONS
Thus far, the only app i have verified to work RELIABLY is TABLET TALK, which is currently $2.99 in the PLAY Store.
You may need to install PIE CONTROLS to have the MENU BUTTON functionality first. PIE is free in play store - Afterwards:
Install on Both, android phone and the smart watch.
On the android phone you are using, setup the device in settings >> at the bottom >> The phone should be selected as PHONE
On the smart watch, go into the same settings menu at the bottom >> The device should be selected as tablet
On both devices, you should press the bluetooth icon.... Both will turn yellow, and then GREEN, when they paid. DONE!
PERFORMANCE
Using a TOOLBOX / RooT app (such as Rom TOOLBOX or Trickstermod) recommendations below to help performance and battery.
Scheduler --> Change I/O to DEADLINE - This will increase SD Card read Speeds --> The stock is CFG, Deadline is usually faster!
Governor ---> Try ON DEMAND Governor. Can help eliminate over-heating without sacrificing performance. Stock is Hybrid
XPOSED FRAMEWORK
.A number of apps will not fit within the visible area of the device without changing the DPI. Confirmed that Xposed and App settings works with the ZGPAX and can be found here http://forum.xda-developers.com/showthread.php?t=2072081. For example, in the ADW popup dialog you cannot change screen borders or change wallpaper until you change the DPI to 100.

USEFULE APPS
Some useful good apps that install and work for this device. Will update frequently with your help: ​
Battery Monitor Widget - This widget may help updating the battery percent and reflect more accurately at all times.
Awesome ON OFF - Similar to galaxy gear, turning the watch activates screen on, with vibrate
Shake Screen ON OFF by Freebooks - Simple shake to turn the screen on or off - no need to use home button
CPU SPY is good for monitoring deep sleep... in case you install an app that keeps the device awake.
ADW EX Launcher - 4x4 grid is perfect, runs smoothly, can stretch clock widgets and such
Active Apps - Good for clearing apps and Ram in one convenient location
DigiClock - Large 4x4 clock with built in themes
Frama Root - For quick rooting
Google Maps - Be sure to actually download and install from the playstore or it may not work
NO Lock - Removes lockscreen and you can sleep / wake watch from whichever home screen you left off at
PIE controls - So you don't have to always be hitting the hardware POWER and Back buttons... also allows many toggles
ROM TOOLBOX - All root tools, file explorer, boot animation etc etc
thanks for your works
i wainting arrive my device :laugh:
Volume Change
Since mine isn't here yet, I guess someone else can test this. It's from the Joe's Tech Review website and it's for a different model, but it might work.
Z1 smart watch phone Engineering code. (Bas Advalvas)
INCREASE CALL VOLUME: found it!
Finally found it. And it's easy! Call sound value is too low on the Z1, 1 of it's main drawbacks.
■Start the phone dialer and dial: *#*#8787#*#* This will start Engineer Mode on de the Z1.
■Select Audio, then Normal Mode. Choose the 'type' Speech, change the value 6 into 0 (that's the loudest) and press Set.
■Press the Back button once. Now select LoudSpeaker Mode. Choose the 'type' Speech, change the value 24 (?) into 10 (on my Z1, the value 0 made the sound very soft, probably because of the system that prevents feedbacklooping from speaker to microphone (how you call this?)) and press Set. Press the Back Button a few times to leave Engineer Mode.
That's all! The standard call volume increases a bit (40%?), but the handsfree volume (which is otherwise about the same as the standard) inceases a lot (150%?) AND the annoying interference sound is now gone!!!

The speaker is incredibly loud... and being that you haven't actually received your zgpax, i don't think you will need any volume increase.
Would you describe some of the customization you've performed with ADW-EX in order to get such a great look? I haven't used the pay version before, so perhaps it is a silly question, but how did you get such large icons on the main page?
I'm considering buying this watch. Two questions:
1. How does it handle notifications from my phone?
2. Can I use Bluetooth to connect my phone to it since I don't want to put my SIM card in there?
zNiiC,
Check out this other thread: http://forum.xda-developers.com/showthread.php?t=2507033&page=8
To answer your questions directly, not yet. It is designed to be a stand-alone device (that being said it may happen eventually).

Yea I've seen that thread. Could you possibly tie your smartphone to this watch with some sort of app to recieve notifications on it?

Humm. Bummer. I think I read somewhere that someone used mysms. Not sure if it was in the other thread or for a different watch.
If you really want to make it happen, you can use Tasker, Zapier and Pushover to do the job. Here's a useful explanation intended for a different application. Bottom line: if you expect to transmit more than 100 notifications per month, you'll have to shell out some ridiculous money.

To BigBison420 and ItzSnitz,
Couldn't you use tasker along with either open watch or notify my android since you can install apps on this watch? (Not quite sure how these apps work). Might be worth a shot to see if it is able to send notifications.

Im using 1.3.3.8 which is an over hauled update of the app... All prior versions are clearly not as good.
I downloaded digi clock widget, which has tons of built in theme and stretches out nicely (4X4 widget).
Also disabled action bar in adw, disable dock, and grid set to 4x4 for the homescreens. That's really the foundation of my cosmetic tweaks. Also i completely disabled lockscreen as described in OP so immediately the watch awakens to the clock on the homescreen

Hi guys,
Newbie here. I too bought the ZGPAX smart watch about 3 weeks ago, OEM version. I also purchased another model EC-309 from HOPU watches, which is based on similar hardware MTK6577, Android 4.0 and with the extra that it has 3G network, different hardware layout (camera on the side not front).
Purchased the ZGPAX for around 140$ odd plus shipping, EC-309 on the other hand was priced above $230. Full disclosure, I own a retail store selling OEM Android tablets in Indochina and would like to add smart watches into my product portfolio.
I would like to get some tips on how to extend the battery life seeing as some users managed to be able to get 1 to 1 1/2 days use on a single charge . Rooted the devices, lowered the CPU range. Tried basic user stuff like, screen timeout, brightness. Switched from 3G to GSM. Still cant get more than 6-8hr battery life. Have tried DX battery Saver Pro, this really extend the batt life but at the at the expense of shutting off wifi and 3G (not acceptable solution). Any other ideas?
For those who might be interested, here's a comparison of the two devices
1) ZGPAX touchscreen runs much hotter than the EC-309
2) ZGPAX has superior speakers, music sounds clearer and louder, no distortion at higher levels
3) ZGPAX has SD card slot, EC-309 only has internal 4GB
4) EC-309 slightly better finish, aluminium bezel, ZGPAX feels a little plasticky
5) Similar firmware for both models. Same issues, Google voice, Skype, Facebook crashes or does not work.
6) Similar battery life - 6 to 8 hr max
7) Similar battery monitoring issues - battery indicator not accurate
8) Both models have good wifi and 3G reception
9) EC-309 comes with Launcher 8 as a default..Win 8 style launcher, no custom launcher like ZGPAX.
10) EC-309 uses micro SIM , ZGPAX regular SIM size
Will share more on apps that work for me soon.

Really depends on how you use the device.... i could get 3 / 4 days out of it, simply using it as a watch to check the time. Streaming wi-fi and videos and downloading stuff is a whole different story. Have you tried changing the CPU Governor? I have not lowered the stock cpu settings... mine sits at 1001mhz max and 250 min. Deep sleeps about 90% of the time

Much thanks for the quick feedback BigBison! Frankly the watch gets fully used most days, I am actively chatting on WeChat, checking time, playing around with some basic voice recognition apps (utter, voice reading). Am trying to squeeze as much as possible out of the device. Will try to lower the CPU settings to half 667mhz and see if that helps. IO on deadline and Govenor OnDemand.
BTW, Any devs out there want to help with Custom ROMS? Am happy to donate towards the purchase of a smartwatch for the dev if it can help resolve the battery, Skype, Facebook and Voice search issues.
Also heard from my OEM supplier in China that a new version with Android 4.3 will be coming out early 1st Quarter 14. Will keep you guys informed.

Also if you find useful information or good apps for the watch let me know so i can update the OP in the meantime for other peeps.

There's also Augmented Smart Watch Pro (Play Store), however I suspect it's still the same issue that ZGPAX is a phone, not a watch. Might be worthwhile to reach out to those developers to check their pulse on this application.

How to improve audio with Viper4Android (Root required; tested only on Lollipop)

The other day I went looking for an audio DSP to use on my Shield Tablet running Lollipop. I came upon some posts recommending "Viper4Android" and went looking for a away to install it.
Here's my instructions, adapted from this article: http://www.droidviews.com/guide-viper4android-make-work-lollipop-lrx21o/
Download "TestLolliViPER_v2.3.3.0.zip" from this post (pre-Lollipop users can download ViPER4Android FX from the official thread and install the APK, skip ahead to step 5)
Change to permissive mode with SELinux Mode Changer from the Play Store (required for Lollipop, maybe for KitKat too)
Enable developer options and uncheck "Use Nuplayer" (Lollipop only)
Reboot to recovery and flash the zip you downloaded; reboot back to Android
Open Viper4Android and let it download its drivers (reboot required)
Open Viper4Android and under settings switch "FX Compatible" mode to "Compatible"
FX compatibility mode caused most apps to not use V4A. Leave it on the "Normal" setting instead.
Specific apps:
For PowerAmp, enable MusicFX under Settings > Audio > Advanced Tweaks, turn on "Tone/Volume". Also, switch off the Equ, Tone and Limit under Tone/Volume
For GoneMad Music Player, select "Use External DSP" under Preferences > Audio > Equalizer
Spotify appears to just work now.
Effects:
Turning on "Speaker Optimization" makes the Shields' speakers sound less tinny
Try some IRS files to imitate/replicate various bass boost, etc effects from various manufacturers
Alternatively, try some headphone correction filters (these attempt to flatten the frequency response of your headphones, making music sound the way musicians really intended it to sound)
See also the explainations for all of the settings.
I hope this works for other people. Tell me if I've made a mistake or left something out.
Thanks! will give this a try soon, what about boosting volume? I haven't seen anything for boosting volume yet in lollipop
Folks will discover this after clicking the first link: this solution requires Root. I've heard great things about Viper, and if you have your device unlocked and rooted, give it a go.

Oh right, thanks for that. I keep forgetting that not everyone has root access and a custom recovery
And even though I've been reading XDA for years, I've only written a few posts.

Yes, there is the "Extra Loud" option, with three strength levels.
Does this method work with Spotify? I don't think you can change audio settings via the app and don't these V4A instructions only apply on an app by app basis?
I've tried this and it doesn't appear to have any effect on the sound on my shield. Followed instructions exactly but makes no difference to sound quality regardless of what player I use.

Try playing with the settings--specifically the NUplayer toggle and the settings in PowerAmp (if you're using it). In most guides for Lollipop for V4A, it says to turn off NUplayer. But for some reason, on my other device (a G3 with CM12), I need NUplayer on. I don't have to use compatible mode on it either.
It's a stretch, especially since the OP tested his steps on this device, but I don't think it'll hurt.

I just had a try with Spotify and it seems to work with no changes required. It even opens V4A when selecting 'equalizer' in settings, so it appears to be quite aware of external DSPs.
Soundscape also has no settings for audio, but doesn't go through V4A. I don't know what to do about that, besides complaining to the company.

I was referring to Beat's claim that their bass-heavy headphones make your music sound the way the musicians wanted it to. Tyle from Inner Fidelity (who has tested many headphones with a pretty sophisticated setup) has said:
I would think most recording studios in the world use a curve called "flat." That way they know what they're hearing on the monitors is what's going onto the disc. The Audio Engineering Society is filled with engineers who write papers and learn about how to achieve a flat and neutral audio response, and then design and build the gear that goes into recording studios. I've measured four of the Beats full-size headphones, and a handful of their in-ear models, and they deviate significantly from flat.

The headphone correction files I linked to attempt to flatten the response of each headphone, making them sound more like professional-grade studio monitors (speakers) or headphones.
The V4A mod sounds great, but it seems to break streaming audio to the Shield Controller.

[GUIDE] [ROOT] Get the best sound out of your Idol 3!

Hi y'all fellow Idol 3 users! And welcome to my guide which aims to help you make your phone sound exactly how you want it to.
Okay, so if you bought this phone, chances are you wanted a great media consumption experience, since this is the Alcatel Idol 3's strength. When I got the phone and first plugged my headphones in to test out all that JBL stuff they were advertising, I couldn't help it but feel let down. Yep. I found it sounded muddy, disorted and clicky. But since we are talking about android, I knew I could probably do something about that. Plus I KNEW the audio chip in this phone was great. So I started tweaking and I finally can say that my Idol 3 sounds like a beast.
Here are the steps, then!
1. Disable the JBL setting. First and foremost, please, pleeease... go to settings > sound and notifications and disable "JBL". Honestly, it just doesn't sound good. It introduces a LOT of disortion in exchange for a little bit of bass. They are much better ways to get bassier sound without hardly disorting it, trust me. I don't know what they were thinking... this setting just assassinates the music IMO. However you are free to do as you want, of course.
* For step 2, root is needed.
2. Install Viper4Android. The following steps will guide you through the installation of this godly piece of software. For you guys which don't know what Viper4Android is, it's one of the best sound engines (in my opinion the best) available for android. It originated in China where it became really popular. Installing Viper4Android will not alter the sound signature in any way, it will just unlock the true potential of your sound-related hardware, getting rid of bottlenecks that worsen audio quality. Just installing it WILL get you a better sound. However, it also provides lots of settings and tweaks to change the sound signature if you want to, and they work really well, unlike this JBL setting we were given. In order to install it, you can either follow my own instructions or head to the official V4A thread and follow the steps there.
2.1 Install Busybox. Download one of the many installers in the Play Store, open the app and click install. Reboot if it asks you to. You can safely delete the app afterwards.
2.2 Download the Viper4Android apk from the official site. Be sure to download ViPER4Android FX 2.3.4.0 which is the one that works with Lollipop.
2.3 Extract the zip and then pick the apk called "ViPER4Android_FX_A4.x.apk" and put it in your phone's storage, then install it.
2.4 Install the V4A driver. Open the app and it should prompt you to install the driver. Select "Audiophile quality" for the best sound quality. Even though it warns you about high cpu usage, I did not notice lags or battery drain. However if this worries you a lot you can always choose "high quality" instead, though I wouldn't recommend it. It will ask you to reboot your phone, do it.
2.5 Make it run along enforcing selinux. This mod normally wont work with enforcing selinux, so you can either change selinux to permissive mode or just flash this zip (by XDA member maximumentropy) through custom recovery, wich will make it work with enforcing selinux. I recommend the second method.
2.6 OPTIONAL STEP: In ViPER4Android's thread the instructions say you have to edit the next lines in the "build.prop" file, which is located in /system. Lines to edit:
Ipa.decode=true to lpa.decode=false
tunnel.decode=true to tunnel.decode=false
lpa.use-stagefright=true to lpa.use-stagefright=false
I found that the second line was already set to false in my device. If you are not in stock rom you might not find this lines, if that's the case just ignore this step.
This step is optional because I used ViPER4Android for a few days without doing it and everything seemed to work. So if you prefer not to mess with the build.prop you can try without doing this.
2.7 Enable ViPER4Android. Open the app and you will find there are several tabs: "Headphones", "Speaker", "Bluetooth"... just activate the first checkbox in every tab if you want ViPER4Android working globally.
2.8 Turn off conflicting settings in some music players. Most player should work fine out of the box, but in some cases there are settings that conflict with V4A.
2.8.1 Poweramp: turn off EQ, tone and limiter. Go to settings > sound engine > advanced customization, and untick the first checkbox. The other settings didn't seem to conflict for me, but you can try disabling them too if you are having trouble to make it work (I have them all disabled).
This section needs expansion! Tell me how you made your favourite music player work with V4A.
2.9 Test it out! Play some music and open V4A. Click the dropdown menu and choose "Driver status". It should say:
NEON Enabled: Yes
Enabled: Yes
Status: Normal
Audio Format: Supported
Processing: Yes
If that's what you see, then contrats! Everything is set.
3. Grab a nice sounding music player. The consensus is that the one with the best quality is "Neutron Music Player". I do agree with this, however, the UI is really crappy and I just cannot cope with that scroll. That is why I use Poweramp, which also sounds nice, and has the addition of a nice little "punch" in the lower frequencies. If you know some other great sounding players be sure to comment below and tell so I can expand the guide!
4. Get a nice pair of headphones. The included ones by JBL do pretty well for the price they are valued at ($40) but that doesn't mean there aren't better choices out there! Also they didn't seem to fit comfortably in my ears with any of the sizes inlcuded. If you want something with a similar price and an even better sound, I recomend the Sony MH1C, a pair of IEMs you can get for $30 but sound like some good $100+ IEMs. If you want traditionally shaped headphones then my recommendaiton is the KOSS PortaPro (or the KSC75 wich are essentially the same but with a different form factor). They are also dirt cheap and have a very decent sound. For more recommendations you can ask me (though I am no expert) or just head to the Head-Fi forums. You won't get better advice anywhere else when concerning headphones! These guys really know their stuff.
Lastly, I hope this guide is of use to some of you and allows you to enjoy the Alcatel Idol 3 to the fullest. I wanted to contribute to this great device's community since I felt it diserves way more attention than it is getting. And by the way, english is not my first language, so please excuse any error I might have made!
FURTHER TWEAKING:
You will see that ViPER4Andoid has a lot of settings, especially if you select the "Expert" UI setting from the dropdown menu. If you want ideas and advice on using them, head over the the official V4A thread.
Thanks!!!
I use n7player. It produce nice sound with v4a combo plus convolver set on studer +1db updated. Also tried shuttle+ but n7 has nicer interface.

Under cm12.1 do you need to disable "audiofx" before using v4a?
Attached is a flashable zip which should add the 3 lines mentioned in post #1 to the build.prop and remove any duplicates. The zip can be used to add ANY lines to the build.prop. You just add the lines to the tweaks.txt file inside the zip. I did not create the zip. I just modified it to put the 3 lines mentioned in there.
Code:
lpa.decode=false
tunnel.decode=false
lpa.use-stagefright=false

Thanks for the guide..installed v4a tonight....seems to be working fine with spotify and bluetooth. I didn't use @Nikola Jovanovic's "cleaner" because it seemed to remove alot than just a few music apps...I used titanium backup to uninstall audiofx and I have n7player full installed (was free on amazon appstore)...haven't used it yet though.
It does, but really I don't see the reason to not apply it. Google cam is better than cm's, viper + n7 is better than apolo + audio fx.. So on, and so for..

It seemed to be doing something with vending.apk which is the google play store...I didn't want to chance that getting deleted. I use google calendar and it looked like it might delete it as well...will have to research when I have time and maybe modify.
It may also be the cause of apps crashing, but haven't experienced any reboots as the other users.
GPS stays on your phone, it deletes aosp cal but I installed Google calendar for that purpose.
It would be awesome if you could modify it in that way so the bloatware is cleaned but all other core apps are intacted.

What do you think about Phonograph? Is it a valid music player, speaking of audio quality?
I just finished installing. All works fine so far. Testing some settings but think it's an improvement over "stock"sound. I really like the jetAudio music player. Been using it for a long time and think it's one of the best out there.
Thanks !
Thanks!!
Thank you! Works amazing with PowerAmp and Sennheiser Momentum On-Ear. Thought that sound was amazing already but now It's 200% better!
Or if you don't want to root simply use DFX player.... ?

What to use as a system wide equalizer?

The apps I've tried so far simply don't do anything.
Anyone know a solution?
If you are rooted, use viper4android, best system wide equalizer.
There are some issues most people forget about or aren't aware of. First of all, there is an EQ already installed. Snapdragon Audio or something. Google hides the system EQ in music apps. I know you can get to it from the settings of Google Play Music, but suspect it's accessible in other music apps. Secondly, Android can only use 1 EQ app at a time. You have to disable the System EQ for any 3rd party ones to work. This is done by going to Settings -- Applications -- Toggle Show System Apps -- and select MusicFX. Disable it.
As for Viper4Android -- Yes, it's a great choice, but the Snapdragon EQ built into the Essential is pretty comparable (but lacking features/options). Viper4Android can't handle usb-c audio, though. On the Essential, it thinks the USB-C dongle/adapter is the Phone Speaker and thus, you have to adjust sound via the Phone Speaker tab. This means fewer options. I've checked around and it's not a problem with the Essential phone but one for several phones lacking a 3.5mm headphone jack. I am going to wait until Viper4Android is updated to support this. Sadly, this app doesn't get many updates and for a year (seemingly) it appeared to be abandoned until version 2.5.5 dropped.

I'm using v4a via the Magisk 14+ module from repo (latest version) and it's actually working via the Headset with the factory dongle. The phone speaker settings also work independently for tuning the on-board speaker.
I'm not exactly an audiophile, but it seems to be doing its job just fine.
I'm on NMJ32F, so maybe Oreo is a different story

That's great! They must have fixed it since I tried it. I'll check this out later. Are you using anything for init as it's required in the module description or using Lineage?

No, even with init utils, I wasn't able to get anything with Audio Modification Library to work as the AML 2.2 module itself was causing Magisk to fail entirely to the point it lost root and couldn't read its own logs, so I gave up pretty quick.
I'm using ShadySquirrel's ViPER4Android FX for Magisk v14+. It didn't process at first, but this was resolved by copying /magisk/viper4android/system/etc/audio_effects.conf to /magisk/viper4android/system/etc/vendor/audio_effects.conf
I tried several hours to get v4a working, and never even had the files you mention in those locations to copy.
also, gk1984, the built in equalizer doesn't work system-wide. It works on apps that support it.
edit: Okay found those files this time. Why do we have to install a separate apk to get the interface to show AFTER installing the magisk module. I seriously don't get it, but okay so I got that file copied over and the only version that will let me download the driver is the io_test one I found somewhere around here. Will test later.
edit: Just keeps asking me to download drivers every single time I reboot. I got past this once, but I don't remember how anymore.
edit: after 3 or 4 tries it seems to have gone through.
Edit: But despite all that effort, it just says processing NO. Can't get it to go.

There are some issues most people forget about or aren't aware of. First of all, there is an EQ already installed. Snapdragon Audio or something. Google hides the system EQ in music apps. I know you can get to it from the settings of Google Play Music, but suspect it's accessible in other music apps. Secondly, Android can only use 1 EQ app at a time. You have to disable the System EQ for any 3rd party ones to work. This is done by going to Settings -- Applications -- Toggle Show System Apps -- and select MusicFX. Disable it.
As for Viper4Android -- Yes, it's a great choice, but the Snapdragon EQ built into the Essential is pretty comparable (but lacking features/options). Viper4Android can't handle usb-c audio, though. On the Essential, it thinks the USB-C dongle/adapter is the Phone Speaker and thus, you have to adjust sound via the Phone Speaker tab. This means fewer options. I've checked around and it's not a problem with the Essential phone but one for several phones lacking a 3.5mm headphone jack. I am going to wait until Viper4Android is updated to support this. Sadly, this app doesn't get many updates and for a year (seemingly) it appeared to be abandoned until version 2.5.5 dropped.

So if EQ is already pre-installed, then each music app can use it and EQ needs to be adjusted in each app or do these apps have their own built-in EQ?

If the phone has it's own EQ built in, which is MusicFX or sometimes AudioFX in the system apps (other phones might have something else too), then I am fairly certain it's universal -- set it in any app and it works throughout all apps. The problem is Android treats EQs as music-only features. So some apps are not affected by it like YouTube or other video apps, likely games, and notification sounds.
With that said, some apps have their own EQ that only affects that app. I don't use these much so I can't say if one overrides the other or if the app EQ is combined with the OS EQ.

I will search for apps on the phone to see if and what apps are pre-installed for EQ. It is kind of sad if YouTube or other video/audio app won't use EQ that was set in another app. I believe EQ should be in the settings of the phone under Sounds for example.

I agree, it should be in the main sound settings section, not hidden. You can get to the EQ in the settings of Google Play Music. I only mentioned it being called MusicFX (which is the name for the Essential) because you have to disable it to use another EQ app.
Also, if you remove Deep Buffer (it's in the system code, not an app), then EQ effects should work across all processed audio. I've only done this with Viper4Android though. You can remove deep buffer with a Magisk Module.
I've tried the remove deep buffer, the v4a, and disabling the built in EQ (cause it didn't work either). The thing is, nothing works permanently on slacker radio. I did find some free app that works, you just have to turn it off and back on whenever there's a pause in the music that causes audio signal to BT to halt.

I finally tried this suggestion this morning with no success. V4A doesn't process with this module and copying the files you mentioned and rebooting for the file copy to take affect. But now that we have a pretty capable TWPR, I might just flash the ARISE sound mod. It modifies system, which goes against the point of Magisk, but maybe it'll work. I used to use it on my last phone.
Update: ARISE doesn't work either. Won't process, likely due to enforcing SELinux (I don't want to change this for security reasons) and not sure if it fixes the issue of audio effects being tied to Phone Speaker tab in Viper.

In regards the the C-port being read as speakers, try going into your developers options. I use a Stylo 4 no Root and I get an option called "Disable USB Audio Routing". This in theory should stop your phone from making that error.

Viper4Android and Arise4Android (both of which I have used before/still use) work on this phone and on Android 9. My best guess is you didn't disable MusicFX. You can check by opening an app that works with the default Android EQ such as Google Play Music, go to the settings, and then tap EQ or Equaliser. If it launches Viper4Android, you should be good to go. If it opens Snapdragon Audio+, MusicFX is not disabled.
If this test launches Viper4Android or you did disable MusicFX for sure, then Exit the Viper4Android app from the 3 dot button and open it again. I have had to do this on occasion.
Change the bools from false to true in /vendor/build.prop that involve saying anything about Dolby.
Thank you! This actually worked! @lexOehm
Fwiw, since someone recently commented on this. If you use Viper4Android the best feature you can use is the Input Response Profiles feature. There are a few out there

The best ones are the IRS TubeAmplifier And Technics Preamplifier ones. They make your audio sound warm is the only way I can describe it.

OpenKirin AOSP for Honor 8 on Mate 9

I've been running OldDroid's OpenKirin for Honor 8 on my US (C567) Mate 9 for a few days and I'm very happy with it. It fixed the main bugs I've experienced with EMUI 8 since the Oreo upgrade. Those bugs include widgets not updating after a half hour even when exempted from battery optimization, some apps not working (e.g. US Topo, a GPS hiking app, that was battery-optimized to stop even when exempted from battery optimization), and EMUI's favoring its own launcher over third party launchers like Nova, sometimes to the point of crashing. Then there were irritants like apps that I don't use that couldn't be removed, EMUI lockscreen wallpaper whose magazine no longer updates. If I wanted to be tightly controlled, I'd buy an iphone.
So with Wirmpolter's patient help, I took the plunge and installed AOSP, specifically OldDroid's OpenKirin for the Honor 8. This is a treble-based OS, with some specialization for the Kirin processor. I've written an installation guide aimed at a relatively inexperienced installer:
https://forum.xda-developers.com/showpost.php?p=76231795&postcount=23
All of my major and minor frustrations with EMUI have been resolved. All my apps work. All the hardware works (although I have to turn off the equalizer to get music to play through the headphones). The camera and video work great. Battery life is good. You can install without replacing the stock recovery, which is good because if you don't touch the stock recovery, it is pretty much always possible to unbrick your phone.
If you are eyeing a new phone or thinking about rolling back to Nougat because of your dissatisfaction with Oreo/EMUI 8 on the Mate 9, then I'd suggest trying OpenKirin. It worked for me.
Hi! Does the headphone jack work with 3rd party music players and video players like say VLC? I have a lot of music on my SD so will the app be able to read it? Also, compared to stock EMUI how would you rate battery life?
Thanks, looking forward to this.
Although, not willing to be a guinea pig at the moment. Hoping some others will try this out and give some feedback. Definitely, need a fully functioning camera, including video.
Works with VLC

VLC works with headphones -- I use VLC, though my main music player is Music Folder Player Full, which also works with headphones. (If you carry a lot of music organized into folders, check it out.) Neither app can see the SD card, so you would have to move music to the main storage with the Files program in order to access it with VLC. I carry about 10GB of music, so I copy all of it onto main storage. Again, to make the headphones work, I use Simple Tiny Equalizer to turn off the equalizer. You can do this in app, too.
I'm finding battery life about the same, possibly a bit worse. I used to end a day with about 30% remaining, and now I end it with 20%. Small sample. I might be using it more intensely, though, or EMUI's aggressive battery management that disables widgets and apps may have saved some battery.
As an aside, VLC can see my local network, like a Windows PC. I can play music and videos at home from my NAS. I didn't know Android could do this.

My willingness to be a guinea pig was very much influenced by (1) having a pretty great backup phone (ZTE Axon), which I set up first and used during the process and (2) the time I was spending looking at new phone announcements and reviews, gearing up to ditch my phone. But I like the Mate 9 -- fast, big battery, big screen, fantastic camera, headphone jack -- and I don't really want to start carrying a USB-C to 3.5mm dongle around. There was nothing wrong with the phone except EMUI 8.

The Mate 9 is the best phone I have owned so far and I am considering the Mate 10. I hate the pro version, don't like those long skinny screens.
EMUI 8 is okay (I don't access settings often and I don't have any issues using Nova Launcher), but I would like to get rid of some of the locked in software (Duo, Facebook App Manager, Email, Gboard, Google, Google Play Movies/Music, Hi Care, HiSuite, Huawei Home, Huawei Mobile, Music, Notepad - a lot can be disabled but why not just allow deletion?) and I would really like to use OpenGapps Pico. But I really need to access my ExtSd from PowerAmp and Moon+Reader, so that is the real deal breaker.
Are you able to use OpenGapps? Does the vanilla Oreo come with Google's bloatware too?

I'm with you on the long, skinny screens. I carry my phone in my shirt pocket most of the time, and it just barely has its center of gravity below the top edge of my pocket. Any taller and it will fall out even more frequently.
EMUI occasionally asked to replace Nova, and would crash if I added a EMUI widget to the homescreen. I hadn't realized how many apps couldn't be removed. For me, Facebook App manager is especially awful as I'm not on FB and FB track non-users, e.g. through the Like button on third party websites.
Not all the Gapps were embedded but some were. I think I had to add Gmail but Play, Google (search app), Chrome etc were present. It appears I can't uninstall the Google search app. (Of course, with the phone rooted, I can.) OpenKirin is not a vanilla AOSP in that way.

The reviews are too negative, especially claiming popups, for me to try this. I'm not saying that the reviews are accurate as they often are not. But I've had to hard reset sometimes to remove a pernicious app, and this one isn't worth the risk. Sorry.
A cleaner version of android is more likely to run any app that didn't come from the phone manufacturer.

Ya, I remember having an issues with one or two widgets, but then I decided I didn't want all that stuff and just made three widgets using KWGT widget maker and I haven't had any issues since, except occasionally the music pause/start doesn't respond.
I was able to remove many apps, but those I listed, and most of those can be disabled. Still, would rather have a clean ROM.
Some of these app issues are Google changes. I used to use ROM Toolbox Pro to remove apps but Google made them remove the feature. I think Google is trying to force more apps like Chrome and Search on us. I don't use the Gmail app, instead I use AquaMail which is a superior interface and I have 7 email accounts that it manages.
Did you try installing OpenGapps? I did on the Huawei Oreo and it installs but then the phone boot loops. I used the pico version which has the bare minimum Gapps. Don't know if the issue is the way Huawei made the ROM or if this is a Google change.
Anyway, the biggest issue is the limited support for the external SD card. Maybe a future update will resolve that issue.
I'll definitely update when OldDroid does, at least fairly quickly, and report if the next version improves the SD card. I'm doing all right with it just as a source of backup files.
I found another advantage of OpenKirin. I didn't get google maps directions over bluetooth in car (an Audi) since updating to Oreo/EMUI 8. I'm not sure why. I tried deleting and re-adding the connection, which didn't fix it, and music and telephone calls played fine over bluetooth, so it wasn't the bluetooth connection. Now bluetooth directions work perfectly, as well as music and calls (which did before).
I took the plunge and flashed OpenKirin - it's decent, limited bloat, but I just can't live with the external SD card access problem. Hopefully, OpenKirin developers will work on it.

How's the performance? I tried Phh-Treble, RROS and Lineage OS, this last two are for the Honor View 10, all of them work, can read external SDCard but all of them have performance issues, when you are heavy using the phone, switching from app to app, copypasting things, taking photos, etc., the phones lost all kinds of smoothness that seems to have when you just flash it.

Sorry, I can't answer your question. I have too much on my external SD to live without it. 300 ebooks 2000 mp3s 400 videos several hundred images
Camera app can't see the storage
Root explorer can't see the storage
PowerAmp can
QuickPik can't
Moon+Reader cant
VLC can't
So after fiddling with it for a while I went back to MHA-L29 8.0.0.368
I haven't noticed any performance issues after about a week of uptime. I don't game, though, so may not stress the system like some do.

Yeah I know that bug, experienced it in Phh-Treble, hopefully is easy to fix and it was fixed on Phh-Treble, so it'll be soo fixed on this OpenKirik AOSP, what matters most to me is performance

I guess it deservers a try-
I finally took the dive and installed this on my primary device last night.
Ran into one issue: apparently, Huawei pulled the unlock request page offline. All of the available links to it that I could find went to a 404 page. (DC Unlocker to the rescue, I guess.)
In any case:
No issues with headphones. A few minor graphical glitches with the volume control panel and similar things but that's about it.
Magisk gets Google Pay and other SafetyNet demanding apps working, AdGuard doesn't mysteriously stop running because of overly aggressive memory management, dual SIM functionality seems fine.
45 minutes SOT, 92% remaining. No performance issues of note, aside from the minor graphical glitches feels smoother than EMUI did.
Update: I found something that gets rid of the graphical glitches, which (so far) seems to have a negligible effect on performance. Turn on GPU rendering profiling to be output to adb, all of the weird scrolling and clipping glitches go away...

I have a "Profile GPU rendering" under developer options, defaulted to Off, with two other options: On screen as bars, and "In adb shell dumpsys gfxinfo". Is the latter what you mean by output to adb, or am I missing something? I hadn't noticed glitches, other than occasionally missing half of the first line of text in some reading apps. With the in adb setting, I was unable to replicate that glitch, but it doesn't happen often, so could be unrelated.
When I choose "In adb shell dumpsys gfxinfo" and then restart, it returns to off.

The latter is what I meant. The glitches I keep seeing are:
1) The volume panel, when it's opening and closing, seems to lose it's edges. As soon as the animation is complete, of course, it returns to normal.
2) In Chrome, at least, when scrolling through a select box, the edges of it seem to stick (top and sides).
I've seen a few others, mostly in the same vein. It usually looks to be as though a scrollable view isn't clipped correctly by the underlying driver, and turning on profiling causes it to render strictly.
I'm not surprised that it turns itself off at reboot, I haven't rebooted this since I got everything installed on it.

I replicated 1) and that your fix works. I had noticed some scrolling artifacts in Firefox, but don't seem to be able to replicate them at the moment. But then, I notice scrolling artifacts on laptops, too. I'll leave it set to adb.
