It's normal for a smartphone device to heat up while playing video, gaming, or charging, but you can reduce it by doing the following:

  1. Turn off uncommon functions and applications such as Wi-Fi and GPS;
  2. Turn down the screen brightness;
  3. Close the applications running in the background regularly, clear the cache regularly, and keep enough running space at all times;
  4. Uninstall the program that may generate a large amount of abnormal heat during operation;
  5. Do not use the phone during charging unless necessary.

5. How can I do a hard reset (factory reset) if I can't turn on my phone?

Generally, you can perform a hard reset in "Settings - Backup & Reset; - Factory Reset" after the phone is turned on. If it crashes, do it in recovery mode. Press and hold Vol+ and the power button for more than three seconds, find "Wipe data/factory reset", and click "Yes - delete all user data". After this step, select "Reboot system now".
