SOLUTION: hello, i have found by accident how to fix this. It is not a software problem. Its a option enabled for those oho have cracked screen or thouch is not responding. In order to fix it turn off your phone and hold all 3 buttons pressed, volume up down and power buttons . Hold them untill some options show up. And turn that off. That should fix the problem . I Hope this helpped .
Note: i creatted account to help u guy and oho sever has this problem. I know how it feelhave a good day!!*
