I bought a Nexus 4 (LG E960) yesterday, and from the first moment there was a problem that it did not accept touch in the line of the volume down button. In a horizontal line, half a centimeter (1/5 inch) high, in the full width of the screen. If I tried to click in the line, it happened above or below. If I tried to slide a widget through the barrier, there was a visible jump. If I tried to sroll a list, it was interpeted as scroll-stop-click. So a random list item was selected. Quite disturbing.
I was sure it was a hardware problem, because the line was at the same place when I held the phone horizontally. Then suddenly the problem was gone, scrolling, sliding was smooth again. For 2 hours. This morning the line was misbehaving again. Now it works fine. I have no idea what triggers the bad behavior, and what stops it.
What could I do? If I take it back to the shop, they will sit on it for a week, and they might not even encounter the problem, much less solve it.
Did anyone have similar problems?
