My touch screen doesn't work
I have tried a force reboot but my iphone 4 still doesn't someone please help me
The LCD may be bad. Have you tried a new screen or "tester" screen?
Is this after a screen replacement the touch didn't work, or did it just stop working the original screen? If it just stopped working, then you will probably need a screen replacement.
sounds like a bad digitizer consider replacing or invest that money towards a newer iphone
