I never had these problems. Apps closed in low memory situations.
A couple of significant bugs I had on the XA2 are gone. I kept trying to ask the forum if it was just me but never got an answer.
-
Using net-heavy Android apps on my phone often broke the hotspot. This no longer happens.
-
Android map applications no longer crash every ~15 mins. HereWeGo works a treat.
-
My third-party 5V charger works every time on the 10iii.
I mention these because I can’t find my original reports and other users may be having such problems. If you are having major problems, and can figure out how to back up everything, it may be worth a fresh installation.
