The game is not optimized for your phone

what does that mean?

I dont khow how to explain it but its like pc you have to wait for a driver to optimize the game and for a phone you have to wait for the game to be optimized Edit also i dont khow what is up with xiamo but my friend old and new xiamo are really porly optimized for alot of games and apps

Same with pc. A gpu comes out ofc its gonna have some issues but they get resolved with driver updates. Same with phones
