How to get call recording with any means necessary? - Samsung Galaxy S8 Questions and Answers

I have been googling and spending days to get a definitive answer.
I got a S20+ 5G last week, so my S8 on Android 9.0 was demoted to my secondary phone. I use my secondary phone just for call recording because in my line of work, I sometimes have to record the conversations I have with people, with their knowledge that its being recorded.
Till now I used a Sony Xperia Z3 on Android 6.0.0., which allowed call recording apps, but now I want to switch to my S8.
As the S8 is now my secondary phone, I am prepared to do anything necessary to get this function, even if means I have to root, trip knox, loose the fingerprint sensor or what ever.
I just can't seem to find a definitive guide on how to root a Exynos S8, nor if that will enable call recordning, or which apps to use when I eventually root my phone.
I have the SM-G950F model, Mar 1 Security update. From what I gathered, I can't downgrade to oreo or nougat because I have previously updated to Android Pie and the bootloader won't allow it.
Can anybody give some advice?

Can I use the google camera app of 6.0.1 on 7.0?

Hello guys.
A silly doubt here, but I can't figure out this yet. Is there any way that I can use the Google Camera app of 6.0.1 on 7.0+? Since I made the update to Nougat the camera app turn into a [email protected]!#$% It's starts to take 3 or 4 seconds to take a picture in HDR mode and, seriously, I cant accept this. When I was in MM the app was working perfectly normal. I do wanna to keep the Nougat, but with the camera app like this, is kinda impossible. Please guys, I expend my last mouth searching a possible solution in every corner of the internet e and can not find anything. I would like to use the version 3.1.024 of Android 6.0.1 Marshmellow on 7.0 Nougat. Is there any way that I can do that?
Thanks!

External Speaker useless after 8.1 OTA update (impossibly quiet)

Not, rooted, located in US.
Before I did the OTA update to 8.1 last night, my external speaker worked fine, both for speakerphone calls, and media playback.
During my first use of 8.1 today, the external speaker is now so quiet (on full volume) that it's useless in all but the quietest rooms.
Calls on speakerphone are barely louder than if I just shut the speaker off. Watching Youtube on full blast is barely discernible in an average noise environment, and forget listening to music outside or in the car.
Anyone else experiencing this?
Same problem here
It's a official software bug. Most of the people who updated Oreo got this issue. If you want to use your phone use any other custom ROM available here. Otherwise need to downgrade to Nougat. If you can wait for another update from Moto to rectify this bug means bare with this volume issue untill Moto releases new update to fix this.

Thanks for the feedback. Unfortunately I doubt Moto will ever release a fix for this.
I never bothered rooting this phone, I guess I am going to find out if its even possible, now that it has Oreo on it.

Rooting stock Oreo is even easier compared to Nougat, because you don't need a custom kernel anymore. Still I would advise to use the new Loony Kernel or ElementalX for being able to use different RGB values if your device has screen retention problems.
Other observations from this OS "upgrade:"
My phone now struggles to stream Youtube to Chromecast... video/sound sometimes is choppy... previously no issues at all.
Sometimes the phone randomly decides Wifi wont work. Can flip the switch to the on position, but it still says "Wifi is off." Only recourse is to restart the phone.
Overall very disappointed. Can't wait until I get a chance to root and ditch this OTA update.

Caller id privacy while locked

Looking for my phone to blur who is calling while locked. How do I achieve this much needed function? It was a part of my last s9 update and I liked it. I switched to S10+ a week later and assumed it would be standard on S10+ and cant seem to find this function. Help!

Rooted OP6T Users in the U.S.A., Please Answer a Question/Do a Test for me.

Hi,
I'm trying to figure what options there are for robust call recording apps on rooted OP6Ts.
I'd like to know if a specific call recording application functions on Andriod Pie after rooting the device.
This application
here's the app: https://play.google.com/store/apps/details?id=com.appstar.callrecorder&hl=en_US
If those running a rooted OP6T would install the app and make a few calls I'd appreciate it.
Here's a number to Health and Human Services Office of Civil Right (all prerecorded menus; we won't bother anyone) to do test calls: (800) 368-1019
You may need to do some basic setup. Make sure call recording occurs automatically, or allow the overlay and manually engage the call recording.
For those willing to go to some effort, if at first the app doesn't work, the "Recording Settings" can be tweaked.
I don't know what the difference is between methods, other than that they change how the app tries to get voice data to record.
Can you hear both yourself and the the caller in the recording?
What recording settings were used?
What format did the recording save to (AAC/MP3/Wav?)
What is the sound quality of the recording?
Do any of the above change if you plug in a USB-C earbud/microphone or earbud/microphone attached via USB-C to 3.5mm/TRRS.
(note: bluetooth headsets have compatibility issues even on phones the app works; headset would need to be wired for this test, though info on Bluetooth would be nice if one is so inclined to provide it)
In the applications inbox for recordings, does the number or contact information show up, or is it listed only as "outgoing" or "incoming" call.
Alternatively, I'd be interested in any information/experiences rooted users may have with other call recording software. Such as Another Call Recorder - Unchained (https://labs.xda-developers.com/store/app/com.nll.acr). In particular, reliability and call recording quality (as good as 'the call').
Note: I'm aware Native Call Recording can be enabled via ADB. I have done this in my testing. The sound quality is awful on the OP6T I have (which is unrooted; uncertain yet if I need to return).
It seems the OP6T or the OP6T I received has issues with AAC/mp4 and other codecs, which may or may not involve something to do with how it's handling sampling rates - I recall reading that certain ROMs cause issues with audio frequency/sampling. It's a mystery to me. Looking to gather more information and hope that members of XDA can assist in this.
theres a magisk module to enable call recording. works perfect. at least it does on my 6t. recordings are clear. no issues at all. root your phone and try it. no need to install a recording app. the module even works on android 10 so.

Well, so my understanding is the Magisk module basically enables the native call recorder.
I've done that via ADB without rooting the phone and the call recording quality is poor. The the call recording apps still don't work properly. Though some of them can use the native call recorder to record calls. But again, audio quality is poor.
Meanwhile, my galaxy s5 on Marshmallow records with excellent sound quality. Though some calls get missed or have issues, which why I want to upgrade/resolve this problem.
Also, the need to note who a call is from and what was spoke of so as to create a call database that allows making sense of matters, I need that to be able to go back and sort through notes. An app lets me do that: date, time, person, with brief synopsis of most relevant information taken directly after the call ended and was saved.
Anyways, I'm not sure if it's a problem with the phone I received (it is 'refurbished' via Amazon Renewed) or a problem with the 6T, but every application I've tried to make a voice recording or call recording using AAC or MP4 runs into this poor audio quality recording issue in addition to the 'other party' not being recorded. This poor audio quality issue exists even with the ADB command and native call recording. Meanwhile, if I call my Galaxy S5 and just speak through the OP6T through my earbuds connected via USB-C dac, the S5 records a perfectly audible call recording.
So...I was hoping to hear more from other 6T owners and see if rooting could be expected to change any of these problems, or at least determine if these are problems that can be observed by others. It's kind of hard to assess if rooting will help out without committing to keeping this phone. The moment I root, it's hard to return it if things turn out to not work out the way I need.
Rooting the phone takes 5 minutes, installing the module less than one. You'll have your answer in less time than it took you write your posts.
Experiment instead of being in the abstract. You'll know then if you have to return the phone, after uninstalling root. From OnePlus point of view, rooting doesn't invalidate the warranty.

I'm running the latest Open Beta, and pretty adb savvy, just a little confused by AB partitions lol. Thank you!

why can't you restore the phone? the normal msmdownloadtool is for international 6t's theres even one available for the t-mobile 6t to return it to t-mo's firmware. do some looking. it's all available on this forum.
also why not try android q. why pie for this. i don't see the point in pie when q is out and pretty stable atm

So, I doubt they'd appreciate the phone being rooted. You're quite right that the most expedient method would be to root and find out, just one I hesitate to try. If rooting didn't turn out to be a solution, I must return the OP6T to the Amazon seller.
Looking into things, I've learned the OP6T has a history of problems with microphone audio in third party applications. And a post at one call recording app developer's forum suggested some phones have issues with sampling frequencies that are caused by ROM issues.
Some OOS update notes indicate fixes have been made in some versions for mic issues, but I'll have to update to see if the issues I'm encountering are the same they addressed. I'm trying to find the right ROMs from a trusted source to update the phone, as the auto-update just sits there and tells me 9.0.11 OOS is 'up-to-date'.
Strangely, OnePlus doesn't offer previous firmware's via their support site, just the latest, which updates to Andriod 10, and I have more issues with call recording exist with 10 than 9.

Does Andriod Q have some benefit to call recording? I recall a news article that postulated Google might be restoreing call recording, but it remains unclear if, how, or when.
OnePlus don't care about root. You can do whatever you want with your phone as long as your don't mess with hardware. It doesn't void the warranty at all. But if you prefer to colocate things it's up to you. Good luck.

Well, when I chatted with their support they said their official recommendation was to not root. Which is pretty much what every manufacturer says. I'll keep it in mind. Going to await OnePlus supports assistance tracking down an older OOS version to flash; see what they does.

google actually removed the ability to record calls in q. even there api is no longer allowed. the reason for this is because call recording is illegal in probably 90% of the world. however since it is legal in a few places(specifically places oneplus sells there phones) oneplus allows it if you enable the feature by toggling it on. hence the magisk module for it. the call recording magisk module that installs an app also works really well on q but it's 10$ for the full app that gets installed. for me it was just easier to enable the built in feature. besides why pay 10$ if you dont have to.

Does Andriod Q break call recording for OnePlus phones, or does the toggle still work?
Does rooting restore call recording to Q in other phones?
Do you think it's possible to create a custom ROM that adds back the call recording API to Q so that full call recording capability is restored?

why would it break it on q on oneplus phones. they have there own implimentation of it. it's disabled by default but can easially be enabled once on the official oneplus software. and yes this includes converted t-mobile 6t's
why would rooting restore call recording on other phones. this isnt other phones threads this is a oneplus 6t thread. you wanna know about other phones go ask in there threads not here
no. as i said google has disabled the feature in q and dropped the api for it so no it is not possible to add it to a custom rom that i know of.
you want anymore info ask elsewhere as i really dont know much more then what i have already mentioned

Camera Question

Longtime listener first time caller,
I am getting a Galaxy S10+ Dual Sim Exynos Unassigned and Factory Unlocked. I'm thinking about using the Hades ROM, but before I pull the trigger I wanted to ask if I'll still be able to do 3D photos and if the picture quality will be the same...? Do would I still be able to use the Samsung camera app? etc. I know that won't be able to switch back once I make the change so I'm just trying to do my research first.
