Hi Adam. According to the Game's specs requirement, the device needs to have at least 2GB RAM. Try closing all the apps not used while playing the game by going to Settings -> Apps -> then force stop all the apps. Hope that works.
Phone is a Motorola Moto G5. Game is family island on Google playgames
Hi Adam. Which game and phone are you using? Maybe you are low on memory? Try closing other apps then try playing again.
