Iphone 5s touch screen not working?

I cracked my phone awhile ago and one day i woke up and the touch screen function was not working, I thought it was because i needed to get a new screen, so i did. But now i have the new screen and it still isn't working, what can be the problem?

I don't have apple care so can't take it into them.

You don't have to have apple care to bring it to them, make an appointment at the Genius Bar at your nearest apple and they will take a look at it. Apple care enables you to get a free phone if they have to replace it, most likely the screen wasn't put on right and the calibration was off. If you did it yourself you can't bring it to them it has to be the original screen that was on your phone. If they can't fix it you'll have to pay for a new phone

  • Why is my iPhone 4's touch screen not working well? I have an iPhone 4, and has recently stopped working properly. When I unlock it, it will sometimes take at least 5 swipes to work. It's even worse when I try to put in my passcode. In the middle of playing a game or texting someone, the touch screen will stop working, and I can't tap. The home and power button still work just fine, but I need to power off and then back on again to get it working again. If anyone can help, it is greatly appreciated.
  • My Iphone touch screen isn't working? I dropped it while bending over, and now whenever I go to slide to unlock, it doesn't move. When I go to power it off, the cancel works fine, but again, the slide bar won't work. I restarted it, and when I do this, it automatically brings up the passlock, and when I go to type it in, only the 1 - 2 - 3 and 5 work… So I can't unlock my iphone at all. Does anyone know what I can do to get it working?
