For now I've switched to Lineage:

-> Browser is unusable
-> no Videochat with Riot possible (or no native Riot Client, or secure Jabber or Signal Client)
-> battery consumption (Xperia 10)

Still I'm missing the OS in general. Gestures are way nicer implemented than with Android. Card/Caldav OOTB is also a very fine thing.

Maybe sometime in the future again.
