Game lags on some devices

Hello!

For some reason my game causes massive lag on some devices. The game is for android and works fine for my and one of my friends sony devices (4.4.4).
My other friends have a Lg ooptimus g and a samsung galaxy s4 mini and for them the game buttons are unrrsponsive and react 20seconds after beeing pressed.
The strange thing is that thw game worked fine on the samsung when i launchee directly from unreal. Any ideas?
