Touchscreen not working - known issue?
I have been repairing a couple iphones now and sometimes people come to me and say that their touchscreen does not respond properly?
What I mean:
- Ghoast clicking
- Not acurate clicking
- Freezing up
Is this a known issue with Apple or someting?
Because I also know somebody who never got his screen replaced, and his phone freezes up regulary.
Or is it just bad quality screens?
