OK -- replying to my own post To resolve the issue, I decided to revive the old 'ubtd' app. Its new incarnation has passed the code review and v0.1.1 is now available on the OpenStore. You will find it under the name "Ratatoskr (Bluetooth file transfer)", in the "Utilities" category. If you install it, may I suggest that you check the README here: https://github.com/petroniusniger/ratatoskr/tree/main for a brief description of how to use it most effectively? Also, should you discover any bug, please report them here: https://github.com/petroniusniger/ratatoskr/issues

@playforvoices Hello, Would this apply now in 2026? I thought that the bootloader should be left unlocked.

Just as @applee, I suspect that this thread possibly discusses several different bugs. Notably, I believe the problem described in reply #3, and maybe by @kristatos are the same as the one I described in this other topic. The issue in that other topic is related to how UBports interfaces with the android gps drivers and it affects all apps using gps on all ported android phones released since around 2020, but possibly with app-dependent symptoms : freezing, crashing, or just going on with a frozen location. The good news is that the other topic's bug has a working fix which should hopefully land in an upcoming OTA.

@kugiigi Thank you, will check it out ^^

@eipapp6 where were you trying to install it using Virtualbox or Virt-Manager or something else , most probably you did not turn on the hardware acceleration and OpenGL it needs that for display

Hello, personnaly, I m found of the fossify apk (on android - https://f-droid.org/en/packages/org.fossify.calendar/ ). Calendar, note, contacts... they are great quality and cover a large needs. most of all, it will help androids (lineage) users to switch to UT... I don't know if the code is realy open and how difficult it is to port them (i have no any competences in app building). but it could be agreat advantage for UT ?

@GooglyBear No. I use a phone case with a keyboard now. So non issue for me now but still an issue for OSK.

Could someone post the FairPhone 3 Android 10 image? I cannot find it anywhere
