touch unresponsive

The title said it all. When I touch the screen with multiple fingers, the screen become unresponsive which very noticeable to a small swipe. This can be "fix" by charging the phone while playing the games or interacting with the screen.

Hi there people, So it's happening from the last few days. I play Fifa Mobile a lot. So from a couple of days, I am having a problem with the touchscreen I guess. My players don't shoot properly, sometimes it's unresponsive, they lost control and shoot nowhere. But other games work fine though...
