Solved it this way :
- Complete re install the factory firmware : https://drive.google.com/u/0/open?id...fhnHGCidYS6CA8
- Do not open, update, or install “ MOBDRO” app
- Go straight to very recent online update to : A95X_F3_AIR_M_9.0.0-202003090926
- After update, go to settings > screen resolution , remove auto select and select a proper screen resolution, according to your tv. This was causing much instability, together with over heating.
