Hi, new to XDA but I have been having a problem with my unlocked & rooted LG G2 D800 running 4.4.2 recently. About 2 weeks now.

The top of the touchscreen is unresponsive. Did nothing that I know of to cause any damage to the screen. It started with just a small portion where the notification bar is located. Couldn't drag the notification bar down was pretty much the only problem. Then the area began to get larger. But then it would get smaller. It stretches from one end of the screen to the other short ways. At one point there was a small line that would register touch in between two unresponsive areas. At another point the screen started working fine for 3 days then began to act up again. Now the screen registers touches that aren't happening. Turned on a setting in Developer settings that allows me to see small dots where the screen is touched and sometimes it will register 5, 6, even 7 touches at once all in the unresponsive section of the screen. Sometimes one or two or three. They happen in both short clicks and long presses. Sometimes one point will register and stay in the same spot for a while, happens in random different spots in the unresponsive zone. It is a real hassle at this point because when it starts happening it clicks anything in it's path, pulls down the notification bar, zooms, posts, opens apps, etc.

Tried doing a factory data reset, didn't help in the slightest.
Tried updating touch firmware in the hidden menu, again nothing.

Looked it up and it seems to be a semi common problem with the G2. A lot of people are crying software issue. So what my question(s) would be are, does anyone on xda have the same problem? Has anyone found a solution? Even more specific has anyone found that flashing a different ROM works/fixes the issue? Like CM11 say because it's in a stable build? Maybe it could be a hardware issue, loose connection, something else but it's frustrating as hell and it would be nice to find out it's something easily fixable before I start ordering parts. Thank you! -Damon
