Just in case you get pissed of with many notifications of the Signal Messenger “Background connection enabled”:
You can disable it by launching Android Settings through AlienDalvikControl or from shell (ssh) via the command apkd-launcher com.android.settings:
- Select
Apps & notifications - Select
SignalfromRecently opened apps - Select
Notifications - Scroll down to
OTHER - Untick
Background connection
I set this ages ago, but it was reenabled with a recent update and forgot about this solution. Hope it will help.
