Updated from 2.0.8 2018-04-03 to 2.1.1 2018-12-24
As a consequence App permissions is no longer accessible because it keeps saying: "package installer keeps stopping" and WiFi keeps getting reenabled after a restart (I never use it).
After downgrading the problems goes away.
I even tried a factory reset and downgrading to Android 5.1, and then upgrading again to Android 7 - 2.0.8 2018-04-03. It works fine. And then trying 2.1.1 2018-12-24 again - voila! - the "package installer keeps stopping", when trying to enter App permissions, reappears and nothing can be done except downgrading.
I put it to HiMedia that something is seriously wrong with this update. Anyone?
