Devices (especially high-end ones) really often get heated while running time-consuming games and applications — this is normal. However, if you are concerned about the heating of the device, you can reduce it in several ways:
1. Close other apps before starting the game.
2. Play on a device with at least 50% charge.
3. Check for updates for your device.

If the heating of the device affects its proper operation, we recommend that you seek further instructions from the manufacturer.
