I'm looking for an app that I can install that will track all the activity that is done on the phone. My phone is making sounds as if it is taking a picture and I want to find the app that is doing that.
You could use an app like GSam Battery Monitor or Better Battery Stats (both require adb commands) that will let you see all the processes being used by your device - You could also use Safe Mode to try to determine if it's a user app (Safe Mode would disable all user apps) & by process of elimination you could try to track down if it's a user app or a System app 🐧
