IPhone 5s screen randomly stops working?

I have the iPhone 5s and all of sudden the touch screen will not work. Right when I'm scrolling through or even in the middle of a text the screen freezes. I know my phone isn't frozen because the home button and lock button still work. The only way that I've figured out works isn that if I lock my phone and then unlock it it will temporarily fix the screen for a couple minutes and then it will freeze up again. I've done so many hard resets and shutdowns… Any reasonable explanation?

Turn off put in box trade for an Android seriously apple suck just wait for a software update

This happens with my iPhone 5s too but not so much. What I usually do is lock it and clean the scree with a rag. You have to remember to turn off your phone every now and then because having it on all the time will make problems like that happen. I'm not saying turn your phone off every hour just turn it off when you go to bed. Other than that I'm not sure what else to do. The touch screen problem usually goes away for me after that. Hope this helps!
