Screen touch issue - docofkult - 11-16-2020
So even though I didn't really play much with the Braveheart model, I decided to get the upgraded board. After the installation I started noticing that the left side of the screen acts a bit strange to touch events. I can't recall having this issue prior to the board swap but now it is the same for both the old and the new board.
I have been running Manjaro and first noticed that something was a miss when I could not tab the leftmost keys on the virtual keyboard. However, events where still detected but for the key to the right. I'm not sure what to think as the rest of the screen are accurately detected so it doesn't seem like a calibration issue?
I have tried reseating the cables and also tried postmarketOS where the issue was reproducible. This of course will not rule out a software issue but then I would believe that I would be more widely reported?
Have anyone experienced the same or have any ideas to how to fix it?

I think you've already tried everything I would have suggested. Given it's now happening with both boards and more than one OS it seems likely to be a hardware issue with the touchscreen. Can you see any damage on the FPC or flexy? I hope someone else has some better news for you.

Hi thanks for answering.
It seems like it is the flex cable next to the headphone jack that is the touch panel controller. I will make another attempt at reseating the cable but otherwise it likely got damaged during the first swap.
Pine64 sells replacements but I'm not sure it will be worth it with the import taxes unless the also start selling spare parts from there EU warehouse.
