Z1c touchscreen issues after 5.0 update

[ryanx]

Hi, after updating to lollipop 5.02, i have problems with my touchscreen. Times when my screen won't recognize my fingers. Its so frustrating, when someone is calling and you can't answer the call. What if its an emergency call ? Can someone help me what to do? Please. 😞

If you just upgraded over your old Kitkat version, I'd suggest that you do a PC Companion phone repair, this will do a clean installation of the latest firmware and will also wipe your internal memory. Don't forget to back up your data before you proceed.

Open PC companion -> Support zone -> Phone/tablet software update -> Repair my phone/tablet (blue link style). Follow the steps given, do not connect your phone until prompted to press volume down while plugging USB cable.
