Hello everyone, I hope you are all doing well. I am facing a critical issue with my Fairphone after updating it to the latest Android 13 release on October 2nd. Unfortunately, I have encountered a persistent black screen problem during the boot process. I have tried several troubleshooting steps, b…

Hi everyone, Thank you for being so active on this topic and helping each other out. I read all your comments and shared a summary with the relevant teams. We’ll look into why after upgrading to Android 13, some Fairphone 4 devices experience a black display during/after boot. It seems there is a …

Thanks for the hint using a USB-C dock to backup my data. Since I’ve never thought about doing it that way, how will it be done? I am worried about the installed apps, their settings and my other data. And how would I use that backup to restore it in case I need to? Doesn’t need to be a detailled…

Cool!! :smiley: :+1: Especially that we found a solution to get the broken FP4’s working again together. And all this without any help by any Fairphone emplyee. Actually that was fun and it was some decent trouble shooting work. So, everyone affected: enjoy using your phones again. …

Well, appearently I did. :sunglasses: I used to try several Custom Roms before coming back to stock, I can’t even say, which ones I didn’t try.

To me it sounds more like a configuration/setup difference. Which means your phone on the SW side is obviously not the same so it’s not stock. Same non stock as if you reinstall windows on a OEM laptop. There are several options on the reason in my opinion: If people for instance flashed A12 inst…

Thx! I reckon, I need to extract the boot.img myself from payload, since it’s not directly included in the ota.zip, is it?

Appearently, the problem seems to sit somewhere else. Today we had one user, who mentioned he had black screen issues without ever touching the OS or the bootloader. And we have me, who definately had several custom roms installed and still got the update installed perfectly fine.

No idea, maybe its rather here? https://code.fairphone.com/projects/fairphone-4/kernel.html

I moved that post, as this was rather talking about a screen freezing maybe black, however overall working.
