I'm overwhelmed to tell the camera quality of m31s is beyond the expecting. I'm Happy. But the phone freezes sometimes for a 2 sec or 3 and comes back to normal. No heating issue while gaming(I'm not pro but I play for fun). Don't use Fast charging everytime. Use it when necessary. Switch to normal charging mode. Need more speed? Just switch to superfast charging and switch off the mobile.
Caution- Don't use fast charging and work with your phone, it heats up. Use normal charging mode to work with mobile. Make use of all the option available in the phone. It's very handy. Clean your mobile once in a week with the old unused or new toothbrush for the cleaning the ports and holes in mobile. M31s is not water resistant, so beware. Keep clearing the memory it speeds up performance.
Ohh...I have no idea on that issue and I haven't faced. I'll check and get back to you! I used to face network issue and I repeated complained it to my network provider. In a matter of time they resolved the issue and only few sometimes I face network issue for a short duration.
