Hi
I moved from the good old n900 to an motorola photon q (android qwerty slider) and used xprivacy as xposed framework tool for app permission management. When the tohkbdv2 got announced I moved to Jolla.

I tried to get Xprivacy to work with root on the jolla but without success. LBE didn't worked for me either.

Now i use an closed source app , but its the only solution I found which works even without the need to root the android vm.
Its srt appguard :


Downsides : closed source, costs 3,99€ , need to uninstall and modify apps before use, software needs to run in background all the time

pros : no need for root, very detailed network configuration possible (you can deny specific servers), developer is an university in germany
