Please follow the below steps:
1. Switch the data network or Wi-Fi and try again. Make sure to try again in a stable network environment.
2. Clear all background applications to ensure that the phone has enough running memory.
3. Reduce the game configuration (image quality, resolution, turn-off special effects) and try again.
4. We recommend you keep the phone fully charged. The power saving mode will reduce the performance. If the power saving mode is turned on, it can be temporarily turned off.
5. Restart the phone and then enter the game, make sure there is enough running memory and try again.
6. Enter the application management to clear the cached data of the game and try again (the game data will be lost after clearing the cached data of a single-player game. We recommend you back up the data before clearing).
7. Confirm whether the phone has just been updated. If so, try restarting it and try again.
If the above solutions do not solve the problem, please check whether the game and phone system are updated to the latest version.
