IPhone 4s touchscreen not working?

Have an iPhone 4s that used to run on ios 7.1.2 (jail broken). Right out of nowhere, the touchscreen stopped working.
I have tried to restart, clean and even restore it, but nothing seems to be working. Everything else is still functioning though.

If the screen doesn't respond and nothing seems to be working, what does "everything else is still functioning though" mean? What else is there?

  • Why will my iphone touchscreen work only sometimes? I've tried resetting it that didn't help.shut it off and turned it back on that didn't help either. I can slide it to unlock it but then i can't select any icons or do anything.sometimes it will work fine for a few minutes then it won't do anything. Is there anything else i can do without taking it to a repair shop or getting a new phone?
  • Touchscreen on my iPhone 5s stopped working? I can't turn it off because i can't swipe the screen and i my home button doesn't work so i don't know how to factory reset it.
  • Replaced battery in iPhone 5c and my touchscreen quit working? My battery tore up in my iPhone 5c so I replaced it, charged it up, and tried to access my phone. The "slide to unlock" wasn't responding when I tried to unlock the phone. I'm not sure what to do, please help and thank you.
  • My iphone touchscreen doesn't work so how do I transfer contacts? I iphone 4s screen cracked so now I can no longer unlock it but I really need some of my contacts. I tried connecting it to itunes them transferring them to my computer but when I did that the contacts I were looking for weren't there only some of them transfered. What do I do? If I take it to the verizon store could they get All my contacts? Should I just fix the screen then get them?
