For a while, I had an exclamation mark instead of a signal status in the top bar, and some apps didn't realize they were connected to Internet when other worked perfectly. Thanks to AFWall+ logs, I found the issue. I need to allow access to an app called com.android.engineeringmode.
I'm OK to allow access to EngineerMode, but certainly not to all this bunch of apps (especially camera or fingerprints services).
After searching the web, I found that all theses apps are linked in /data/system/packages.xml using the sharedUid 1000. But it is said to never change the UID of an app when it's shared (I didn't really get why).
I'm using the stock ROM (OxygenOS 3.2.8) from OP3, but rooted (got Xposed an Xprivacy too), so it's Android 6.0.1.
Is there any chance I can allow Network access to EngineerMode only ?
