Ihave bought it new many years ago
its like when you type sth or scrolling suddenly the screen goes black(not off but a black screen)
I remember from nougat till now I have this problem but rarely
I am using lineageos 16 official on my galaxy s4 since end of january 2020.
Everything was working fine
Bluethoot, GPS, headset almost perfect.
No particular concerns except battery drain.
I decided to update to the last nightly 19-02-2020 but it was a bad idea.
Since then the bluethoot is going off and on very frequently; the headset does not work during the phone call.
I would like to come back to previous version such as 14_02_2020.
Is it possible to flash that version without wipe everything?
Do I have to flash the gapps and addonsu? Or it is sufficient to flash only the lineages zip file?
I'm thinking about to upgrade LineageOS on my "S4 Active" (jactivelte) from 14.1 to 16.0. Does there any known showstopper (not working features, bugs) with 16.0 ??
I'm asking because NFC does not work with 14.1 on my phone.
Also I will use MAGISK as I do on 14.1. Does it also working fine with 16.0?
Not sure about the rollover thing, but GPS fix I sadly don't think there's much that can be done with it. Ever since Google rewrote Glonass support a few Android versions ago (and broke it for devices like ours which can't update the closed source GPS libs to support it), GPS has been getting progressively worse every new Android version. Sad, but that's how it is, and this device isn't the only legacy device in that situation.
