My phone screen sometimes it's difficulty to touch

When IAM play free fire game my phone is very hang issue

The Infinix Smart 7 does not have a specific screen calibration setting like some other devices. However, you can troubleshoot issues with your phone's touchscreen by removing the screen protector and cleaning the screen, which might improve touch sensitivity. If you're experiencing ghost touch issues (where the screen seems to register touches without you touching it), you can try gently bending the opposite edges of the screen to relieve pressure on the digitizer.

Yes also even restart it self

Your phone is likely having a touchscreen responsiveness issue because the problem goes away after restarting but keeps coming back. This usually happens due to a software glitch, a failing touch digitizer, or interference from a screen protector, case, heat, or moisture. Restarting temporarily fixes system errors, but if the right side of the screen continues to be difficult to touch, it may indicate an early hardware problem. You should try removing the screen protector and case, cleaning the screen, updating the phone’s software, and checking if the issue happens in Safe Mode. If the problem still occurs even after these steps, it is most likely a hardware issue, and the screen may need to be checked or replaced by a technician.
