Hi, I've used for over one year the Call Recorder in subject on Android 10 and the app worked very well with JOneplusTool for recordings.
When it was ready the new Android update 11 I read around the web and I asked to the developer if I could upgrade Android version with no issues for call recordings.
He unsured me that with the new version of Call Recorder (3.4.5) I could upgrade to Android 11 and I also could uninstall JOneplus Tool.
But unfortunately the things didn't go with these expectations because the system recorder method doesn't activate the recording and I found some past recordings with different numbers...the app created a mess..
Now for me this app is very important for several reasons and I'd come back to Android 10 to get the app working properly...
Do you know if 1) I can downgrade the Android version with good results and 2) do you know what is the latest app version worked properly on Android 10?

Rolling back to Android 10 is quite straightforward, download the rollback package and install it as local update. This process will delete all your data.

The file can be found in the thread for Open Beta 1 - Android 11 in the OnePlus forums.

But now I've installed a stable Android 11 (ver 11 0.1.1) downloaded via OTA.
Maybe I can't use the way you suggested me but I need to use a specific procedure.
I hope to fix my issue after this inconvenients..


P.S.: anyway I didn't find the section for downloading the package you wrote me in your reply..

No, as I said that rollback package should work when you start from stable 11.

Hi, there are users with opposite opinions about the correct procedure to downgrade at Android 10 from a stable 11.

it has explained two ways to downgrade to Android 10 which is one is the method you suggested me but I need to go through Android 9 first..

In other place it has suggested me to enter in Emergency mode and to use a program usually used by OnePlus' Technical Support to unbrick the phone and to get a phone as it's just come from a factory state...

Anyway my target is to have Call Recorder in subject working well with Bluetooth earpiece but despite of yesterday's latest release I can't even fix my issue...

That program is called msmtool and it's the best way to have a clean install, rollback or not. It needs a computer and the process is a bit more complicated.

The comments about rolling back to 9 or 10. I've seen people having success with both rollbacks.

Finally I've fixed my issue with Call Recorder.
Truecaller in Android 11 caused this issue on the app despite of the app's updates.
Then now I don't need to do the rollback anymore...
