Fix 5 – Wait for the phone to cool down

If the phone temperature is too high, the phone screen will automatically dim down. So, if you are in a prolonged gaming session, the phone may get heated up. You can feel the heat on the backside or the frame of the phone.

Usually, this is a limiter placed on the phone to protect the device from excessive heat. We recommend that you just put down the phone to cool it off for a few minutes. As the phone comes back to the normal temperature, you can resume playing PUBG again.
