[Q] Htc Iolite touchscreen not working

---

Hi,
I have a very big problem with my friend's HTC Iolite.The touchscreen suddenly stop working.When tapping in one place it sometimes send me to another.I tried installing new ROM but nothing.
It actually works for 10 minutes after installing new ROM but then dies.Tried all ROM updates but nothing.
Is there a solution for this or can I throw it away?
Is the problem hardware or software based?
Thanks!!!

sorry to hear that from you, it's a hardware problem. you have to replace your touchscreen. i had the same problem, but luckily i was still in the warranty period, so i had it fixed for free.
