Hi all.

My phone's display has been getting progressively worse and worse over the past couple weeks. Initially, when I flipped out the keyboard, the screen would get garbled. I could technically still interact with it (it still responded to stuff), but the display would start glitching out and move all over the place. It's like there's tons of scanlines and it repeats the same display again and again.

When I went back into portrait mode, things were fine. This was extremely awkward but I dealt with it because I had little choice.

However, over the past couple weeks, the problem's gotten progressively worse. Holding my phone a certain way would cause the screen to glitch up again. It came to a point where I had to flip out the screen and keep the flex cable positioned a certain way so I could see the screen. I'm using a dull edge to kinda poke that flex cable around and it helped me gain use of the phone, but today it's gotten so bad now it refuses to "undo" itself when it boots and no amount of poking and prodding of the flex cable will help.

It looks almost exactly like this guy's phone (not my video):

Luckily, I was able to get a VNC server installed on the thing, so if you guys think it's a software issue, I may be able to get it to do something, but I'm not going to be able to interact with the phone if I put it into Clockwork Recovery mode, so doing a hard reset is out of the question.

I'm having a flex cable come in and I'm going to get some local assistance disassembling and installing it, but before I do that, had anyone had this issue before? What did you do to fix it?
