Help How to make screen more sensitive Huawei M835

[AndroidPhone13]

My sister and I both got Huawei M835, froyo 2.2.2 from MetroPCS and the touch screen on mine is noticeably less sensitive then my sisters. So I wanted to know if anyone knows how I could go into file explorer and edit some file to make it more sensitive... I saw for a diffrent phone that you can replace some code thing within the phone to make the screen more sensitive. If anyone can help that would be greatly appreciated!
P.S. My sister and I have the same exact phones so I know it's possible

I personally don't know the answer to this question, but would be interested in finding out an answer to this as well, if someone has one.
