i have a motorola g6 which seems to be crashing a lot on some apps one is miniclip 8ball pool,but it seems to crash when the game plays ads,rather than an actual game.i have reloaded the app,but was wondering is it something to do with how the phone plays video?what are the options ,reluctent to re load android for fear of losing everything,but does it mean i need a new phone,is there a way to clean junk safely on android as you do a PC.
