thanks for your answers, @retsifp, @lklaus, @snevas !
The wakelock-problem seems to be solved, as you can read here.
Two other questions:
-
if GoogleMaps is the only Google-App I need to use … Do I really need to flash “GApps-Mini”, as this is the lowest package which includes Maps?
I guess only installing Maps-APK from Playstore etc. will not work, as most likely any google service for location will be missing in this case, right? Any recommendation to get running only Google-Maps/Location services, without the need of the other google-clutter? -
To gain root acces I need to flash the addon-su (arm) with TWRP, that I got.
BUT: do I also need a special SU-manager-App (which now is “superuser” for my current FPOS), or is this already included in the addon or in LineageOS itself?
(Background: For using TitatiumBackup I need root, and I want to be safe that I will have proper rootaccess straigth after flashing LineageOS to get back my backups.)
Thanks for help!
