App unable to use camera

Mike777

Wondering if anyone can help with a problem that cropped up in the last few days whereby an app which previously was able to scan QR codes now no longer seems to be able to switch to camera. The log file for the app says:

08-21 13:41:39.116 4930 4930 I auditd : avc=type=1400 audit(0.0:3721): avc: denied { getattr } for comm="Thread-86" path="/proc/sysrq-trigger" dev="proc" ino=4026532070 scontext=u:r:untrusted_app_32:s0:c144,c256,c512,c768 tcontext=u:object_r:proc_sysrq:s0 tclass=file permissive=0 app=com.barclays.barclayscorporate

Mike777 I could be wrong, but the two lines you pasted from the log here don't seem to provide any information as to why the app cannot use the camera.

Have you verified the app has access to the camera and the camera access is enabled via the quick settings tiles? Other apps can access the camera?

Also, I renamed the discussion so it's easier for people to figure out what the issue is.

Thanks for the quick response. I have the app's log in full in case that's any use.
Certainly checked all the permissions and was previously able to use the app.

Mike777 Looking at the logs, I found the error, but I'm not sure of the cause. It appears to have something to do with Google Play Services. Unsure if it's an issue that can be fixed with the Sandboxed Google Play compatibility layer or not. I'll see if one of the developers has time to look...

The relevant part of the logs that I found are as follows:

other8026 The problem arose between 16th and 19th August so what change happened in GOS in that time?

GrapheneOS

@Mike777 Did you disable Network for Play services and/or Play Store?

Mike777

Thanks so much @GrapheneOS and @other8026 for having a look. Play Services and Play Store both have Network permissions. Would it help you to see the Play Services Log? https://drive.proton.me/urls/VR9QWBQA5M#1CfonDZMqP3U

Mike777 looking through the log quickly, I didn't see anything helpful (of course I might have missed something). You attempted to scan with the app then saved the logs afterward? It might be helpful to have Google Play logs as well.

Mike777

other8026 Yes, exactly. I go to the app and it briefly tries to switch to the camera. I try a couple of times and then go to the log files.

@other8026 @GrapheneOS I have also tried reinstalling the app and GPS but still get the same result.

Mike777 Would you happen to use a VPN or private DNS to block ads on your phone at all? If you do, what happens if you disable them?

Maybe because Google Play Services and Google Play Store were updated around then? There have been a couple of other updates since then as well. I'm unaware of anyone else having these kinds of issues, so I'm unsure what is going on.
