Hi All
First of all: great rom – no Chinese apps, sync getting better and performance is also great
But there is one function I am missing: In my stock rom (with old 5.0.2 Android) I was able to long press the "clear all processes" button (that appeared when long holding the home button) in order to open up a menue where to configure a protection from clearing for whished background processes, e.g. EMail sync or whatsapp. Unfortuately with the 5.1.1. based roms this menue does no longer appear – has anyone an advice where to find it?
Thanks in advance!
this function is merged with nubia security app in newer version…. you need to manage it through nubia security app… that's why i didn't remove the security app.
Hi, anyone realized that the V3.81 is draining battery very fast? I was previously on V3.20 and things were fine. Just thought i try the new update and there are some bit of changes but battery issue is quite troublesome since we can't get spare battery with this phone. Possible fix soon?
