Hi guys,

I just bought a car unit android 8, but the screen sometimes (90% of times) looks flipped left-to-right. Sometimes is also flipped upsdide-down+left-to-right.
And sometimes I get the screen working as it should be, flawlessly, until I do not restart the car.
The defect appears from the beginning, right from the initial logo, and it remains also if I try to reset the unit. Also when I get the "boot" text menu, it appears flipped as everything. (edit - in addition, the touch layer still working in the right way, so I cannot easily understand what I'm touching on the screen, and this makes everything more complicate)
The unit is a px5, 4GB RAM, 8-core, the MCU is MTCE_XRC_V2.93_1.
I didn't already tried to overwrite the android files, because I'm trying to get some assistance from the producer. Anyway the product is coming from China, so I guess I will have to do it by myself. Until now, I rebooted, reset, cleaned, changed startup settings, and spent a lot of time in doing and re-doing all these tasks, but the unit still like at the beginning.

My question for you: do you think is it hardware problem, or can be fixed with a firmware update?
Do you have any suggestion, setting or trick in order to solve the problem?

Thank you in advance for your help.
Kind regards

It looks like a hardware problem indeed. The touchscreen 'digitizer' is apart from the display in the front. You could try if the ribbon cable inside the radio is firmly connected to the mainboard i guess. Otherwise i think a new screen..?
