I've tried going in to the special Service menu by typing *#0*#, and I fail the touchscreen test.
However, the spen works fine.whenever I use it, the phantom touches stops.
But it comes back when I use my fingers again.
I did a factory reset last night. Worked for like 3 hours, then it came back.
It comes and goes. So it's not all the time. It can work for an hour without problems. But most if the time, the error is there.
Any thoughts? Or should I just return it?
