@amir63760 playing games on your phone is very demanding on its hardware. Your processors and memory will be working very hard to continue to deliver a good quality video etc. Now, your M32 is not known to be a power house and that is the reason why it heats up. The ongoing demands on your phone to play games is just pushing it to its limits. Consider games that are less resource demanding or even better, get some sort of game console that is meant for this. The heating up is normal behavior.
