An app or feature on your Samsung is frozen, frozen;
There is not enough battery to power the device;
Actual physical damage to the touch screen.

Boot Phone in Safe Mode
This is another helpful step to get rid of touchscreen issues if it is some third party application that is causing the problem.

If you have a lot of apps, it can take a long time to uninstall them one by one, so you can perform a factory data reset (explained below).

This can happen if you play games or make videos for a very long time. Wait a while before using your phone again.
