There is alot of problems with android im gonna list almost all of them here
1.in android its easy to accidently exit the game but when the game is exited accidently you're punnished with cooldown
2.The android problem with chat:a.when youre dead you cant talk or when at the end of day android players cant talk while pc players can
My reccomendation to solve it
1.When someone exit and immedietly join in you should stick the player with the game /making him still ingame when he accidentlh exits or make a tab to remove cooldown if accidntly exit (but have a reason to remove cooldown/search through his/her log in (something) first)
2.just fix it
