Downgrading from Android 11 - OnePlus 5 Questions & Answers

Hello there.
Some time ago I decided to go from Paranoid Android 10 (Quartz) to Pixel Experience+ (Android 11)
I've noticed that my phone is lagging while scrolling web pages and also PDF files and when trying to switch apps. The apps switching lag happens when I press recents, it takes like 1, 1.5 seconds to actually toggle the apps list. Then this last week I decided to clean flash POSP (Potato Open Sauce Project, Android 11) to see if it was the ROM that was causing stutter/lag/frame drop while scrolling and switching apps, only to my discontentment.
The issues are still here.
I've tried wiping cache through TWRP, I think it indeed helped a bit (the lagging duration now is shorter. Sometimes it lasted 5 seconds or so, while scrolling up and down).
So I decided to go back to Android 10 to see if it helps.
How can I downgrade?
My firmware are already at 10.0.1 (last).
Also if anyone could help with these questions:
Which is a great kernel to go with?
What are other Custom ROMs that are worth testing? Aside from those mentioned in the post and LineageOS.
Thanks in advance for any help!

some issues that are bugging me...need your input

hey guys. i'm a very nitpicky person and there has been a few "issues" that have been ticking at me lately. i wanted to ask to see if it's an issue with my rom (OMJ v3.1 odex) or just general issues with the phone that I have to live with.
1) for a 1ghz phone, it takes FOREVER to load. i'm usually anywhere from 15 to 45 seconds on the splash screen, after which the boot animation plays and maybe 10-15 seconds after the animation ends the phone starts to load....but it goes into the lock screen, and i have to unlock it, and then a million things start opening up, so that from screen off to fully loaded and ready to make a phone call the phone takes at least 1 minute, sometimes close to 2 minutes.
EDIT: just timed it - 45 seconds on splash screen, 25 seconds from end of boot animation to lock screen
i'm coming from a 667mhz WM6.1 phone that would boot, animation and all, be ready to call in 30 seconds or less.
i can live with the time it takes to load if it was normal...but then I hear things on here on how the evo loads in 8 seconds and i'm looking at mine and wondering what's wrong
is this a rom issue (OMJ v3.1 odex), kernel issue (king's #6), android (2.2), phone in general, or a result of all the different things we install on our phones (adblockers, superuser, custom flash, custom boot, etc)?
2) when the phone loads it always opens the dialer. i go back into home screen. throughout the day at least once or twice the dialer will randomly open on its own when i unlock my screen.
3) wi-fi at home is secured through wep2...but at school is unsecured to connect, but then you need to authenticate through the browser. sometimes this works, sometimes the browser (dolphin hd) just stays loading and doesnt take me to the authetication page...and the only way around is it to disable and enable wifi again. then everything is perfect.
is this a rom issue? or a dolphin hd issue?
4) I have LauncherProPlus with their custom icons from the website. whenever i restart the phone the icons for Dolphin HD, Documents to Go, MixZing and Pandora change to their standard icons. i have to restart launcherpro and they go to the matching icons i have throughout the homescreens. then at random points those three icons revert back to the stock icons, and i have to restart launcher pro.
is this a LP problem, a rom problem, or a me-specific problem?
5) perhaps the most important issue - i have problems downloading and installing certain apps in the market. I paid for lcd density changer and installed it. uninstalled it later on. now i'm trying to reinstall and I keep getting an installation unsuccesful message...same thing goes for Rom Manager (which i have installed, but installation unsuccessful with update), and many others. Some programs will update, some wont. Today I tried to download 3d gallery through the market and keep getting that issue.
this has happened with other programs in the past, where I thought maybe they werent meant for the EVO...but many of those had comments from EVO users??? and now some of those programs that wont install are programs I HAD or I HAVE installed!!!
is this a rom specific issue? or a market issue? or an odex issue? or does it have anything to do with having app2sd and move2sd enabler on the phone? none of the programs in question have been moved to the sd card...obviously not the ones like 3d gallery that I haven't yet installed.
so, thank you for reading through all that. any help in either of the issues will be greatly appreciated.
if most of the issues are rom-related i will go hunting for a new, stable rom. if they're general woes that come with owning the Evo then I guess i need to know that too.
thanks in advance!
I can't really help you much in terms of a solution, but coming from a Blackberry the EVO boot time seems very fast! However, the EVO is definitely not an 8 second loader, I don't know where you got that information.
is this a rom issue (OMJ v3.1 odex), kernel issue (king's #6), android (2.2), phone in general, or a result of all the different things we install on our phones (adblockers, superuser, custom flash, custom boot, etc)?

This is just a guess, but I'd say it's the ROM you're using. Have you tried anything else? Make a nandroid backup of your phone now, then flash another ROM and test it out, it's easy to revert with the nandroid backup. Keep in mind the first time you load any newly flashed ROM it will take longer than normal to boot.
In my experience, stock 2.2 and all its OTA updates (and the ROM I use that is based on the latest OTA) are pretty good when it comes to boot times. Anything you install may have the potential to slow things down.
I'm currently using the VaelPak 2.2 ROM with the latest HTC kernel (no 30FPS limitation) which is very stable and very fast. VaelPak stripped out some of sense (not all) and I love how you have the choice between HTC/Sense elements or AOSP. For example, I actually like the HTC dialer, messaging, and contacts.
thanks.
i guess i'm going to have to flash a new rom...but it'll have to wait till next week!
i'll look into the different roms but i had thought of flashing CM6 since I'm not using any sense other than the dialer as far as i know
thanks
any other opinions are welcome!

Are all of those apps saved on your SD Card? I wonder if that has anything to do with it.
yes all four apps are in the sd card. i was using pandora and plugged the phone in to my pc to try to install that 3dgallerym.apk i found on here. pandora stopped (i'm assuming as the sd card was unmounted). after unplugging and the card was remounted i was able to open pandora again...but then the 4 icons had reverted again.
i'm starting to think that is a lp issue. i'll send a message to the developer see what he says about it.

FYI they have their own forum. You should see if it has already been answered there.
http://www.launcherpro.com/forum/
The boot up taking so long is do to custom roms being deodexed.. It puts the odex file into the apks so that you can theme a rom without any problems. Stock roms arent deodexed so they boot up a lot faster. Its the only downside to deodexing a rom.
Also you should try to start fresh.. wipe data and dalvik and reboot. Then see if you have a problems with downloading and stuff. It might be cache left on the phone messing it up. If a clean data/dalvik wipe doesnt fix your problems then its most likely the rom or user error. Try a different rom for couple weeks and see if you come across the same problems.
My rom is odexed...
Im going to try cm6 next week most likely...
Swyped from an HTC Evo on MetroPCS...
First off, are you running a task killer or manager? If so, uninstall and reboot. A lot of the time this is the source of problems. Android manages its own tasks quite well. I can go into a lot more details if you'd like about why you shouldn't use one.
If not using a task killer or that did not help....
I say try Fresh ROM or Myn's Warm. Fresh is very stable. I think you may have a corrupt download of the ROM. However, since you are using LP you don't seem like a Sense UI person so CM6 may be your option. However, it does not have 4G nor HDMI. Personally, I love Fresh ROM. The dev came from the Hero like me and has a very very good track record for being stable and fixing things. And he is a cool guy.
Install one of those and then post back if you still have problems. I think this will fix it.
BTW did you flash from another ROM and use a backup app to restore? This can cause problems with ROMs that have different settings and options.
As for boot times, like the earlier guy said deodexed ROMs do extra stuff while booting. Also, lots of apps can cause slow boots because they start up on boot. You can use an app to disable them.
And last, app not installing. Hit menu-settings-applications-manage applications. Hit the SD tab and see if those apps show up. If so, click on them and uninstall. This will most like fix that issue.
Post back results here or if you need further help. We will be glad to help.

Pandora has always been glitchy. Its a great service, but they need a new programmer.
8 second phone. I think not. Try the Desire Z (G2), their version of Froyo looks faster.
If your new to the EVO, give it some time. Its a smartphone, and anyone with experience knows that all smartphones are temperamental some times, just like computers.

not using any task manager. used to have advanced task killer but someone else recommended uninstalling it before.

im considering CM6 because i barely use any sense apps. mainly flashlight, clock and htc lockscreen. i'm on metropcs so i cant use 4G and i dont have a HDTV so no need for HDMI
Install one of those and then post back if you still have problems. I think this will fix it.
BTW did you flash from another ROM and use a backup app to restore? This can cause problems with ROMs that have different settings and options.
have not done that...and now i know not to do it when i change roms.

And last, app not installing. Hit menu-settings-applications-manage applications. Hit the SD tab and see if those apps show up. If so, click on them and uninstall. This will most like fix that issue.
well the problem is 1) if the app is in my sd card, i dont need to uninstall it, just move it to the phone and then i can update it. but i have over 100 apps installed, it is not practical to do this for every update for every app! 2)some apps, like LCD Density Changer, which I paid and had installed before, wont install at all and i dont have it installed...so what there?

The OP's sig says he has his EVO on MetroPCS; if that's the case then lack of 4G shouldn't be a concern.
That's the only real thing keeping me from trying CM6, even though there are only a few pockets of 4G coverage where I live.
Well I switched roms to ava v9 and some of the issues seem to have gone away...but still having problems installing apps from market...many if the apps and games I had before on my previous rom give an installation unsuccessful message...
Im thinking it may be something I damaged by installing htc and sprint apps right after flashing the rom...I'm going to restore all those files and see what happens...

Westcrips v8.4 Ressurection -> Discussion

Post updated to reflect current version.
OK.. I'm mainly posting this here because my PC is too low to post in the dev thread.. and I think its best to leave that thread to dev discussion...
First impressions:
Installs quite smoothly and pretty fast.
My install method (in case its needed later)
- Back up and copy to pc
- Complete wipe to stock gb. Root gb and install cwm
- Copy ressurection 8.1 zip to SD card
- Reboot to cwm
- Format data/cache, dalvic cache, system and battery stats
- Reboot to cwm
- Select resurrection 8.1 zip and install. Takes about 5 min
- Reboot to recovery and factory reset (probably not needed but did it to be safe)
- Reboot normally and let system boot up. Takes 3-5 min on first boot
Now on to the fun stuff... on first boot I set up language, clock wifi account etc.
I selected and only use nova... I like it better than trebuchet.
Gmail notification crashes Google accounts right off the bat. This is persistent throughout 3 installs. Seems to work fine after initial crash.
Once SD card scanning and such finishes, i disable fast dormancy (*#*#9900#*#* for menu) thenI reboot normally.
Open market, works fine.. install some primary apps... titanium backup & pro key.. better battery stats, root explorer and LCD density monitor pro.
Set dpi to 160 to give me better screen real estate.. then reboot normally
I'm about 11.5 hours on battery and 83% battery with light to moderate use.. I disable mobile data stuff unless I need it, and generally keep wifi active most of the time..
Overall most things run very smoothly. Some apps don't seem to close properly when killed but I assume its due to those apps.
System does get laggy if a lot of apps are open and sleeping.. I use ATK pretty often to keep things smooth...
Problems I've run in to so far...
This one is pretty big I think... when using flashlight from notification panel, if I leave it on until it times out, my phone completely freezes and I have to long power press to reboot or remove battery to get system rebooted. This is persistent and replicated every time I tried.
Gmail app crashes about 30% of the time. Seems completely random. I'v disabled Gmail notification due to this.. (doesn't crash google accounts like above, just the gmail app)
When holding phone I can feel a very very faint vibration coming from the back side up near the camera.. it pulses about once every 2 seconds. You have to very lightly touch the phone to feel it.. like barely touching it. Not sure if its just mine but its very noticeable if you hold it right. Not sure what's causing this.. doesn't seem to affect anything and phone isn't overheating so I can't give more info...
Random reboots are something everyone is aware of so not commenting there. Nova does hang sometimes for 5-10 seconds. Probably due to this being a dev release and such things are expected.
I'll update more if/when I run in to other issues that people haven't really commented on...

android.acore process keep FC..really disturbing..
it bcoz of auto sync and i hope someone have a fix on this
I think v8.2 is the best among Westcripts ROMs. because of the least FC.
V.8.3
Flashed since yesterday , very stable , no FC's at all, however there is an USB problem , PC won't recognise the devised the way it was in previous versions. Nevertheless I believe it's a ICS bug as I found same behaviour in other Roms as well.
Not bad so far using 8.3
I noticed in his dev post he said that official ICS doesn't have blue coloured wifi/signal bars but I've used my friends nexus & his definitely has blue coloured wifi/signal bars when in use.
Everything else seems pretty smooth at the moment.
Looks like this problem with blue bars has been resolved in 8.4 Currently downloading (check change log).
Not being funny, but is there not a thread in the Development section to discuss this rom, surely creating another, just fragments the chefs build

Well actually, that thread is supposed to be for development discussion only; not for general Q&A 'how do I do this or that' like it has been. Which means, if people actually adhered to the rules, using this thread for all the 'HALP' posts would likely make development a lot easier for those working on this particular project. The less spam he has to sift through, the more actual development related posts he can focus on.
Not to mention, as I stated in the OP of this thread, I wasn't able to post my bugs there because of my post count.. So i posted them here, along with some other info (like how to install) about the release.
If only everyone who tried to play forum police actually knew what the dev forums are supposed to be for........
no searching for contact when I typing in number in phone, and T9 is not working in v8.4
Do any of u have the issue with notifications having a 'grey background'? I've had this since 8.3.
Also how can I change back to the stock bootanimation?
Thanks.

I used a app called ROM toolbox suggested in the dev thread to change the bootanimation to the ICS one.
Notifications come up grey here on 8.4.

No issue with the notifications that I've seen so far on 8.4
To get the Samsung boot animation back, do the following:
if you have 8.3 or an earlier version, extract a copy then navigate to extracted file > system > media
copy bootsamsung.qmg and bootsamsungloop.qmg to your sd card
in root explorer, navigate to your sd card > hit menu and multi select. Select the above to files then click copy/move.
Navigate to /system/media > mount R/W > paste.
Remove bootanimation.zip
set back to R/O and reboot phone.

Temporary fix posted by kevjef420:
go to market and install these three apps. ex dialer, ex dialer ics theme and ics adw theme by kovdev.
set the ex dialer as your main dialer in dock. open setting for ex dialer and select ics theme. then long click on the ex dialer icon in your dock and click edit and select adw theme pack and then find the ics blue phone icon.
now you have a very functional t9 dialer that is very similar to the miui dialer and it works great. I am very happy with the results. this is a good fix untill somebody comes up with a t9 fix for asop dialer.
I've flashed 8.5 and set language to German but somehow it's a mix of German and English!?!
Anybody with same problem or similar?
Navigation from Google Maps keeps force closing everytime i have GPS signal. Maps works fine. What could it be?
Thanks in advance!
v. 8.6
Just installed 8.6, really fast and smooth. Hour in use, no more process stopped.
I am not sure why but in one app's browser and in stock Android file browser I get unusual wide slider. It was normal on 8.4, but changed on 8.5.

First impressions of XDA OMNI on Acer a500

I have downloaded the XDA omni rom for A500:
Freshly built Android 4.4.2 ROM based on Omnirom KitKat !
"The Team 'IconiaHD' is proud to present a new ROM for your Acer A500 or A501 tablet.
This small team is composed of:
- HenrikE: A200 owner, responsible for an unofficial CM-10.2 build for the A200
- Doume: A200 owner, experienced linux developer
- macia10: A501 owner, tester"​
The omni rom installs easily using TWRP ver 2.7 by Thor. Once I followed the OP recommendations all stages in the installation were clear. The rom runs well after the second and third boot. I even used ART. Here is my take so far: rom is fast and smooth. Browsers load pages fast, even high image content sites (CNN). Videos on youtube work flawlessly, wifi signal is very strong. I was able to load all my apps and have them run well. A very nice and responsive rom on the acer a500. Google play store works right off the bat. A few minor issues though: google music play app has a bit of chopping of the music playback. Netflix did not work for me as the app would force closed on me. I tried the netflixfix as recommended by the OP but it did not work either ( I am waiting for the next fix as suggested by the OP). Other than those two minor issues I can't wait to try the updated versions of this omni rom as it adds a new life to this acer a500. I am very happy to see that there are developers who continue to get value for us by implementing optimized roms on the a500. Thank you for your great work.:good::good::good::good:

I'm filing a report with the moderators to put this into device-specific forums, as you're issuing a report against an unofficial build that, to my knowledge, no one involved with the bringup has attempted to get merged officially. (I'll check with the merge guys tonight on that...)

Further Update on XDA OMNI for Acer a500 (unofficial)
I have been running this rom for the past few weeks. Here is what I have noticed. I hope that this will help further the development of the rom. I am attaching the logcat information.
a). Recent update from Google Play Music fixed the audio glitches I was having before.
b). Chrome Browser runs well has problems playing videos, causes browser FC (flash issue?). Lightening Browser works well.
c). Occasional window change results in zoomed icons in the apps section.
d). Netflix still FCs.
e). Network Location works on my Acer A500.
f). Youtube works without any issues.

Thanks for the report! Interesting that network location works for you. It seems to work sometimes and sometimes not, would be nice to figure out why..
The latest versions of netflix don't work, even with the fix applied. Try version 3.1.2 instead: http://gsmandroidapps.com/download-netflix-3-1-2-build-1142-apk/
I haven't seen the problem with zoomed icons, does it happen often?

You're welcome. The Netflix 3-1-2 build works after installing and subsequently rebooting! Thank you. The zoomed icons happens infrequently and occurs only when I go into the apps windows from the home screen. It seems to be more of a lag issue when switching windows. I installed Apex launcher and the lag has decreased significantly. In addition, the zoomed icons are no longer present.... so far. I have decided to use Dalvik runtime as the Art function is not compatible with some of my apps.

omni rom for acer A501 by HenriKe
I have tried to flash this ROM several times andi keep having issues. I am on Acer 501.
Op still says to use the 4-27 build for 501 as the 4-29 build has issues.
Issues I have at multiple force reboots. (Kernel panics). Also if data is enabled then WiFi will not connect. I know I should have saved the last_kmsg but just sipped and restored previous ROM.
Still waiting for the fixed 501 version to be posted.
As stated here = http://forum.xda-developers.com/showpost.php?p=52709444&postcount=109
Some tweaks that make this Rom smooth.
I would like to suggest the following tweaks that will make your experience with this rom smoother. Make sure you have a complete backup of your a500 current system. Use these at your own risk.
Before installing rom:
1. Wipe cache, wipe Dalvik cache, "real format" data (very important).
Installation:
2. Install rom, install mini-gapps, install super user
3. Boot up rom. Set up Wifi, Set up Google play services.
4. Reboot.
5. Make a complete back of your new omni rom.
Tweaking:
6. Use "interactive"; "sio", "set on boot"
7. Set cpu to max to 1200 Mhz and min to 456 Mhz
8. Reboot
9. Install Nova or ADW launcher. Have at least 3 screen windows . Set look and field to “faster than light” (Nova)
10. Install "prop builder" editor
11. Edit the prop file as follows (see attached image):
dalvik.vm.heapmaxfree
12m
dalvik.vm.heapstartsize
12m
12. Reboot.
13. Run a benchmark app and compare. I got an Antutu score of 9036 (see attached image) up from 7700. Overall system is more responsive.
14. If all goes well, make another backup with a different name.
Good Luck and enjoy.

Before installing rom:
1. Wipe cache, wipe Dalvik cache, "real format" data (very important).
Installation:
2. Install rom, install mini-gapps, install super user
3. Boot up rom. Set up Wifi, Set up Google play services.
4. Reboot.
5. Make a complete back of your new omni rom.

I think you have a typo. dalvik.vm.heapsize cannot be set to 12m or it won't boot. Maybe you mean from 384mb to 128mb ?

Thanks for the feedback. I made the corrections and edited my previous post to reflect what the attached image of the buildprop file shows.
dalvik.vm.heapmaxfree
12m
dalvik.vm.heapstartsize

Problem waking up
Hi,
I installed this ROM, and everything seems to be working well, expect waking the device from sleep.
It sometimes happens, after the tablet is not used for a while and is sleeping, that the power led is on (white), but the screen is black. If you try to wake the device by pushing the power button, nothing seems to happen. The only option is to power it down by holding the power button, and powering up again. Very annoying!
The device is not docked and not connected to mains power.
I disabled daydreaming, and it seems to happen less frequently, but not 100% sure.
I suspect it has something to do with the tab waking up by itself to do some syncing, and somehow getting stuck.
Any ideas?
How can I try to debug this?
Any help appreciated!
You have the infamous Sleep of Death (SOD). It is/was a common problem with certain a500 motherboards. I don't have the SOD issues.
You should contact the XDA iconia HD development team at:
http://forum.xda-developers.com/showthread.php?t=2705989
I am still a junior member and I don't have privilege to post on their blog, yet.
You may try these (make a back up of you current omni rom first):
1. Ensure that the wifi is kept on during sleep. Go to Advanced settings in the wifi options. Click on check box to set scanning always available.
2. Edit the buildprop file to set the wifi_supplicant_scan_interval to 0 sec.
Cons... decrease in battery life. May not be a significant amount.
If the above settings don't work for you, check the links below.

Thanks for the advice.
I'm also still junior, so I can't post there either
I never had any SOD issues before, not with the stock ICS and the 3 other ROMs I tried before.
Putting scanning always available didn't solve it, but haven't tried the buildprop yet.
Problem is that is is very intermittent: sometimes the tab runs for about 3 days without hanging, then it happens within the hour...

The Iconia Team HD just posted an update for their ROM. You may try that one and see how it goes. Another developer also posted another a500 omni ROM version 4.4.4. light. Try both and see which one works best for you.

Updating to 4.4.4 seems to have helped: haven't had the SoD issue since!

Awesome. I noticed also that sometimes the screen does not come on with one single press of the power button (most of the times it does) when the Acer a500 is asleep. Sometimes, you just have to watch the power button and press until the white light comes on and the screen comes alive (there is no reboot, it just takes you back to the lock screen). I use to think that it was an sod but all is well.

I'm seeing the same thing: the tab won't come alive and I think "****, an SoD again", so I press long to force a power off, and after a few seconds, the screen comes alive! Weird...
For the rest: awesome ROM, much better than the previous one I tried (don't remember exactly which one it was)!

Just had my recovered A500 setup as you mentioned... Yes, it's running OK.
However, AnTuTu (v 5.7.1) just keep failing...after it ran up to around 75-76 %. What ver. of AnTutu are your running (since I notice your screen looks slightly different from mine)?
I found this ROM to be the most stable ROMS available for the A500.

Android 10 lag/freezes

Hi all,
I recently updated from Oxygen OS 9.0.11 to 10.0.0, wiping data during the process. modifications are TWRP/Magisk/blu_spark kernel.
When on 9.0.x I used to suffer from the fairly frequent laggy behaviour ... I haven't seen this since on 10, however more often an app (especially Chrome) seems to freeze for several seconds (maybe up to 10) before continuing.
There are also a couple of places, especially the task switcher that feels laggy.
Has anyone else experienced this behaviour / got any suggestions for a possible resolution?
So far everything is smooth, but I also do have Chrome freezes that I had not before OOS 10.
I advise to you using the Chrome fork "Kiwi Browser", Theme, Settings, and you can install all Chrome extensions even on Android (Nano Adblocker/Defender)

Android 11 Beta

Hello,
I have the option to download the official Beta Android R (RPB1.200504.18).
My Pixel 4 phone is my daily phone, just like to ask, if its worth downloading this beta version.
I know it will not be stable and may be a bit flaky, but will my phone be useable if I do?
Thanks

Been using it since day 1, no major issues here . Working flawlessly, except for Qnap apps that all crash besides the Qfile app.
One thing that sucks about Android 11 is that you can no longer hide the nav bar..

Anyone with a working solution, adb command is welcomed

Thanks, I've downloaded it and I'm having a play with it. One immediate thing I notice missing is the Screenshot option when long pressing the power button.
The icons are along the top instead of down the side (which I think was better), so how do I take a screenshot now ?

My wife had the same question when I updated her pixel 3 to this latest android 11 beta
Normally you can take the screenshot as on any other android - hold down volume down + power button and vollaaaa!
New way to do it also is by swiping up from the bottom and holding, and the besides the switch between apps option will appear you will also see Screenshot, Select, Share options underneath it
Yeh I get the old fashioned way, holding power and volume keys. Why on earth have they taken the very handy button that popped up when long pressing the power button !!!
As for your swiping up option, that doesn't work at all on my phone !!
Swiping up from the bottom and letting go works on my 4XL but only when in an app. If you are on the launcher i think its the old fashioned way. This is standard google to take away things we use!
Just received another beta update (RPB1.200504.020), 8.23MB
I'm able to set Shell as the default Home (Launcher App). What can I do to utilize this?
I'm loving the beta but I've found that when the pop-up asking you to chose what app to open something with, I only get two options: the recommended app and a second one and no list of apps that were being shown in android 10. It's really frustrating when you can't choose the correct app because it isn't listed. For example, what if you want to open the link in the app but you only see two web browsers? I use deampify to strip off the Google AMP part of the URL so I can open a link in the website's app such as CNN or The Washington post. That means if deampify doesn't show up then there is no way to chose it like I could in android 10. Another example is if you get an attachment in an email and you might want to open it in one of several apps such as Adobe Lightroom if you're going to edit it, Google Photos if you're saving it, Dropbox if you're sharing it with your family, Instagram if you're posting it, and what's app if you're sharing with a single friend? See how this can easily be an issue? Anyone else have this issue? Is there a fix?
I used the first official beta release for about a week, here's what I found:
* Good enough for a daily driver, if you don't mind a few hick-ups or manually restarting your phone every once in a while
* Slightly slower launching apps
* Audio quality from phone speakers was no where near as good (sounded thin and boxy), and not as loud.
* Camera would black-screen on me about every 4th launch and I'd need to force stop the camera
* Camera app always warned me it was too hot to preform certain advanced features
* Boot-up, not a big deal, but took about 6 times longer to start back up.
* I liked the notifications on the pull-down better. Not a huge change, but noticeable
* LOVED the screenshot edit pop up after every one (does more than Android 10 does). This was one thing I missed the most when I switched from a Samsung S10+ to Google.
The audio quality and camera were just too much for me to handle right now, so I went back to Android 10 for now. I may try beta 2 when it comes out?
Using Beta 2 right now, no issues at all, device is smoother than ever and battery lasts longer about 36 hours with medium usage getting 3.5h SOT

I haven't been having battery luck. On beta 2 I get about 1.5 hours. Of screen on time. Phone doesn't go to sleep at all. Same with Android 10. I have to go back to using naptime.
I don't have motion sense on or aod display.
