My update on screen replacement

So I've been having the same issues for over a month now, and got annoyed and bit the bullet and ordered a new LCD/digitizer combo. My biggest symptom was that though it got worse with heat, even after reboot, rapidly touching the left and right ends of the middle of the screen forced ghost touches to appear along the middle, and was my confirmation of my issue. The problem usually only got worse after being on and hot for a while and at some points becoming completely unresponsive.

Except for one hiccup where the display didn't come on during the first boot, i just reconnected all the flex cables and viola it worked! The difference is night and day. I am 100% unable to replicate the ghost touches and responsiveness is way smoother. I'm finally convinced this cannot be a software issue (I have a background in mobile test engineering). The whole job took about 4 careful hours, and for someone with experience and courage could probably easily do it in under 1.

Some observations:

1. The model LCD i received was different from what I ended up pulling out. The number on the back of the old one ends in AA2 the replacement AA4. The digitizer also had a few distinct markings the other didn't.

2. The color saturation seems to be slightly off (https://www.youtube.com/watch?v=AiJLF_ct9Yc it seems I am not the only one) I am hoping this will slowly settle over time as the poster of the video describes.

3. The longest part of the process was cleaning off the excess glue. Sharp edges will scrape off the plastic. A small flathead with gentle but deliberate motions seemed to be more effective.

Here are a couple of tips from my experience for those bold enough to try:

1. Watch the videos. All the way through. You'll have a better understanding of what's coming ahead and not skipping steps seems to be fairly crucial. Various cables and antennas are tucked away

2. I used the oven pre-heat the glue. I preheated my oven to the lowest setting at 170F. I've seen 60-70C thrown around so I shortened the time i left it in the oven for. I initially tried it with the towel wrapped around, but it never really sufficiently heated the glue enough. In my opinion the even surface temperature from the plate probably did the most to soften the glue. It was in the oven for around 4 min at 170F and I had to toss it in a second time to get the second half.

3. The glue to only applied to the outer edge. If you go too deep you'll push the lcd. Once i got my prying tool under, I slid it around the circumference, being especially careful around the corners to NOT LIFT the digitizer.

4. Make sure your double sided repair tape runs the entire edge of the frame. The corners seem to be the most susceptible to lifting.

5. Take the time to run through things slowly. Don't force anything, and use consistent amount of force very slowly.

I was able to save my existing lcd and digitizer should mine ever break, (knock on wood) to hold me over until another replacement arrives. If there were some way to send in the lcd and digitizer i pulled out to a lab somewhere for diagnostic purposes, but I guess the outcome may not bode well for OnePlus.
