@YomenT I had the same issue on a Oneplus 6T and found a way to manual switch audio output to USB-C (and back to speakers). Perhaps this will help? You would need to check which plughw device is USB-C

Bluetooth on Focal a UT problem. I had this with a Pioneer digital radio. A developer told me to re-pair it several times. The theater was too weird for me which is why I uninstalled. What you can try is to delete the headphones once and pair them again. Calls were established but there was no sound and the described lost Bluetooth signal.

Yes, some like Open Camera can even use all cameras if you device has multiple.
In regards to banking apps, there's no assurance they will work, it really depends on the app.

What happens to the device screen? It should display a virtual touchpad. If it does that and your external display at least detects it then that should mean it is compatible. There's a bug right now that wired external display only works once. After the initial connection, it'll just display black. You'll need to reboot to make it work again.

@s710 said in How to revert to Android?:

Okay nevermind. Although the bootloader was already stating "DEVICE STATE - unlocked", and every reboot remindst of the bootloader being unlocked, I had to do fastboot flashing unlock_critical (which would ask again if I wanted to unlock the bootloader), and then the flashing tool for FF4 would run fine.

Android was successfully reinstalled.

Thanks for sharing! This post saved me quite some work.

@domubpkm no esim?

@gudaoxuri There's no settings to adjust the resolution yet. However, the aspect ratio should be displayed properly. Perhaps, it's a setting of your display? Though maybe it also depends on what resolutions/aspect ratio FP4 supports. I've only tried on 16:9 so not sure how it works on other aspect ratio.

Same problem. Latest version of focal.

Fairphone 4 6g version.

@Lakotaubp I was holding the power key as well. Managed to reinstall using UBports installer, works again!

Hello
I can install an operating system - postmarketOS, but Ubuntu Touch just doesn't work.
That's a bit strange to me.

@etdoughe excellent thanks for the easy reference and sorry for the simple questions.

I tried the Mint settings on the link you provided and they seem to work great. I seen ~100Mb/s down on a speed test.

@Keneda you are right, I tried it it both ways

Last try was with light always on, using the Manager Libertine Containers START button.
The container options I left unchanged.
Then a download started, might be the Classic Application Support ...
Now I could create a container.
Thanks for your help !

Just checked in FP4 group and yes you can install UT on android 12 but a lot of stuff will break so please don't try. There is also no issue with unlocking the bootloader on 11 not 12. The end.

@fp4_a
Also working from FP4-SP28-factory.zip to FP4-FP4K-factory.zip then ubport installer

@dell
Like said, the fix is to install android 11 back on you FP4 and then install UT 20.04.

I'll add to not relock the bootloader in any case before, during, and after that process.
You need bootloader unlocked on any UT device even after succesfull installing.
