1. Completely close the game.
2. Clear your recent apps list/background tasks.
3. Turn off your device, wait for 3-5 mins, and turn it on.
4. Relaunch the game.
We recommend having more than 4.0 gigabytes of free space at all times on your device to allow an easy download of updates. We also suggest you have no background tasks running on your device while playing for best performance during gameplay.
You will need to delete some old or unused programs to free up some space, so you can play with limited to no performance issues, such as the main character not being fast or general game lag or even crashes.”
Thanks guys, you rock!
