My touch screen is not working in certain places,for example my e,s,w,z and 2nd autocorrect choice don't work when phone is vertical. I dont know if it is software or hardware problem. I am left to rely on autocorrect to type. What can i do to fix it? I thought that doing a factory default reset would help if the problem is from rooting, but don't really want to do that unless I know it will fix the problem. What can i do to fix the screen and what's the problem?
