Mobile game stuttering? Close background apps first
Apps running in the background share your phone's resources and your network. Closing the ones you don't need before you start is a common first step when a game stutters.

What the sources say
Background apps can use up system resources and bandwidth.
Closing apps you don't need before launching a game is a commonly recommended step.
What to do
Open your phone's app switcher and close the apps you don't need.
Pay attention to apps that stream, sync or download in the background.
Then launch the game, not before.
Keep the game and your phone updated, since updates can include performance fixes.
How much this helps depends on your phone and the game. On a very old phone it may not be enough.
