Unforseen Pixel 8 screen replacement issue

Hi there,

I'm the proud owner of a Google Pixel 8 and I'm attempting a screen replacement.

The screen I originally had was broken but the phone would turn on fine, and I could even tap on the screen where the buttons would be and the phone responded fine.

After one screen replacement attempt which simply turned out to be a screen for a different model, I reordered another one and this one turns on.

My problem now is that somewhere between me trying the first screen replacement 100 times and swapping it out for the original broken screen so that I can access certain apps and data - I have done something to my phone and it spams taps and drags nonstop. This started happening with the first screen replacement attempt too right before I stopped trying, it would go on even when I swapped in my old broken screen but at a much slower rate than now.

So I understand that it's not the display and after searching, inspecting my parts and thinking, here's my useful bits of information:

• the pins on both the receiving end and the connector are perfectly straight
• none of the original components on the board got de-soldered
• I thoroughly checked for any microscopic matter that got between the contacts and they're clean
• I noticed some of the tape on the back of my transistors is gone (this is my fault in handling and not knowing better)
• my phone boots and I see the clock and the usual icons for maybe a split second before it crashes and restarts, this only started happening on my second day of trying to figure out if I can solve this issue and have never seen this issue before, which really worries me about what's going on with those unknown taps
• there's an area marked by a little white square slightly up and to the left of the connector which gets significantly hot during the short time my phone is on

At this point I'm looking for some extra opinions and advice.

I believe that it might be the transistors shorting against the connector's cable which has a slightly larger footprint than the connector head itself.

So I will try getting some electrical tape and cutting tiny squares under microscope to place on the transistors, but I'm worried there might be some permanent damage driving this and making it worse as I keep trying.

Therefore, if anybody has done something similar to this, or has some knowledge to share with a newbie that would be much appreciated.

Best regards,
