Hi mate do you mean it randomly boots or do you have a bootloop?
i'm sorry! yeah, it is! it get some ramdomly reboots when the screen is off, and my battery doesnt take longer.
how can I turn off powersave mode without kernel assistant?...
I had the same problem (see above) and, assuming your issue is the same (wild assumption) I do the following:
make sure that the FC cause is the contacts google sync: settings > accounts > Google; tap on your account, deselect/select contacts ...
I discovered what happened. my vol - button was broken, :/
I opened my phone and discover by making a jumper with some iron between the two points, and its worked...
thanks for helps !
