There are a couple of small areas on my LG G2 where the touch screen refuses to recognize anything. Using the keyboard is frustrating because certain letters don't register. I can work around it somewhat using autocorrect and the split keyboard.
I did drop it a couple of times, but nothing else was affected - it is in a case, not one of those bionic (hah) cases, but it's done it's job so far. This phone will be 2 years old in December.
Any ideas? It's been a good phone all this time and I'm a bit bummed that I'm having troubles with it now.
