If your game is running slowly there is a chance that the hardware (either the device or the SD-card) is the cause of the slowness.
The following solutions may improve the gameplay experience immediately. Try one to test it and move on to the next suggestion if it does not help. This way we can rule out different possible causes.
- If possible, reduce the Quality of the game in the game Settings (☰ > Settings)
- Update the game to the latest version
- Try restarting your device to see if that makes a difference
- If possible, make sure the game is stored on the internal storage of your device (rather than the memory card) - this can make a big difference
- Ensure you have enough storage space on your device (>1.5 GB)
- Ensure that your battery is fully charged
- Ensure your device is updated (Settings > Software Update)
Should you see an improvement after any of these actions, then that is an indication of where the bottleneck is and how to solve it.
