PinePhone EG25 automatic test failed

[pepo]

Exactly what happened to me in every single detail (except that eg25 problem is solved if you insert a sim card which doesn't require a pin code).  It looks like brightness is locked at 0% and you can't see anything anymore... imho the system is working, i pressed several seconds the power button and tapped randomly on the screen and it restarted: with black screen again, as a result





A quick update:

I can't really explain why but after a couple of reboots (without SD card) I suddenly got OK on all automatic factory tests. I instantly flashed the most recent Ubuntu Touch build and plugged in the SD card. Pretty much exactly the same thing as described above happened again; weird looking loading screen with the Ubuntu logo messed up (just me?), and after fooling around with the settings it crashed when I was adjusting the brightness. After that it crashes directly on the loading screen.

However, I also tried with the latest PostmarketOS phosh build. From what I can tell, it seems to work just fine.

Could this somehow be a OS specific (Ubuntu Touch) problem related to the unlocked SIM card? Should I bug report directly to the Ubuntu Touch developers?

My time is limited right now but I will do some more testing in the coming days and keep you posted.
