I'm not sure what happened but 10 minutes ago I take my phone, unlock the SIM and unlock the phone then I search for an app and then suddenly without warning, the phone reboots. I have no idea why but all the permissions of MacroDroid were gone (including ADB, which is annoying), and it seems other things happened as my default launcher changed back to the default one.
And my native camera app is still broken...
But then I don't think it was the same thing than the other one.
