Hello, I have Hisense Sero 7 pro tablet, and it was worked fine for me for 2 years, but now it has started freezing. I have tried reinstalling different ROM versions (4.4.4, 5.0, etc.) but it seems that stock ROM 4.3 is most stable one. I have also noticed that it freezes when I go to Wifi settings screen, or enter wifi password (for non-stock ROM I have not noticed any particular pattern/reason for freezing). Then screen goes blank (sometimes light is working, sometimes not), and I need to hold power button for a few seconds completely shutdown and then to turn it on.
I have now watched a few movies from SD card using standard video player and it was working wine fine, so I believe this issue is isolated to wifi related activities only. Maybe someone had a similar problem (as I believe this is not limited to those particular tablets). Is there a way to fix it?
