Screen dying already?

[dsimic]

I don't really know what else you could do other than opening a new ticket, describing that your PinePhone is unusable just over half a year after purchase due to a screen defect, perhaps attaching photos of it and mentioning that your previous ticket was wrongly closed. Persistence is often necessary when dealing with manufacturers (among other players on the market), especially when things go south after they already have your money.

I'd suggest that you provide a few pictures of your delaminated screen as part of the support ticket.  With no pictures available, it's sometimes hard to completely understand what's someone complaining about.

the screen right above of the SoC is extremely overheated when charging, it goes beyond 55 degrees celsius which is the limit for human skin to have continuous contact, still the screen works fine but I believe it will be damaged soon, a solution could be to make the phone thicker by making a silicone pad on the circumference, I have done the same on iphone 6 due to some other problem

55°C may be the limit for human skin touch, but ought under no circumstances be enough to cause phone screen delamination. I don't believe the issue was caused by heat either: I didn't notice the issue worsening after exposing the phone to high temperatures or slowing down after applying thermal throttling. What I did notice was the delamination spreading when the screen was exposed to sunlight. Nevertheless, still unacceptable for a phone.

The thermal daemon for the PinePhone I'm working on will also throttle the battery charging down it if detects the AXP803 PMIC or the battery overheating.  Though, there's quite a lot of additional software support that still needs to be implemented to have that feature working properly.
