@peat_psuwit regarding FP5 and fingerprint:

For me fingerprint works in general.
I thought that maybe related to allowing fingerprint on first android boot (but not setting it up).

But I got that jumping password prompt sometimes when I need to input password for decrypting the encrypted home-directory after rebooting Ubuntu Touch.
A second reboot is fixing it most of the time.
After that, fingerprint works to unlock.

Just for reference.

@Grisen did you check the box to wipe the data partition in the installer?

@musicologist you can also try MirVNCServer App, connect with vnc client from PC and record it there. But I am not sure about audio...

@JPC So, I could solve my latest connection issues by doing a waydroid init -f.

@Kutzi its nothing to worry about, if not all mounts work in recovery, but the relevant (userdata) should be mounted still.

Now just have a look at /data/backups ls -la /data/backups

@JPC lately I've had the same issue. I found that there was set a private DNS in network settings. Unsetting it and resetting the network-connection fixed it for the moment.
But now I have the issue again and there is no other DNS set, so... no idea.

@fair the FP4 does not seem to use the ofono binder plugin yet... Maybe thats the reason.
It also enables voLTE.

@peat_psuwit they get written to /userdata/backups.

@peat_psuwit maybe it should be mentioned somewhere, that there is a backup-job running, the first time, when "migrating" into 24.04.

1. It's a nice feature
2. It may slow down the UI on older devices (e.g. FP3, not sure how it feels on more performant devices) while running.
3. When switching between 20.04 and 24.04 back and forth (for testing), you may run into storage-issues, because every first time 24.04 is booted, it creates a new backup.

@Kutzi everytime, when you switch from 20.04 to 24.04, after booting, the system creates a backup of your user-config-data.
That's also the reason, why the system feels a bit more slow, directly after the first boot of 24.04.
I am not sure if also backups are created, when switching to 20.04 again.

Have a look at /userdata/backups and clean it up.
Maybe do it from recovery: Boot to recovery, connect through adb, mount -a, and then check user-data backups folder.

Everytime you switch, there will be changes in your /home/phablet/.config and other dot-folders, because there is always something that needs to be migrated e.g. regarding system-apps.
So I won't recommend switching back and forth.

@Alain regarding installing:

You need to unlock the bootloader, there are plenty of how to's for that.
For that you will need a PC where the little tool fastboot is installed.
Then you might need to downgrade the device to the appropriate Android version. Usually the ubports installer gives short instructions where to download the right firmware.

After you unlocked the bootloader and the device is running the right Android version, you just use the ubports installer to flash Ubuntu Touch onto the device.

Thats it.

@Moem The thing is... we currently have one port (official one), based on the "full-system-image" build, and a second one based one the "standalone-kernel" method.
The second one, is the one we want to support further. But we somehow need to do a migration, from the first to the second port...

Currently, the plan is to make it available with UT 24.04.
But I am still not sure, how that will work.

@messayisto both ports are targeting both device version, so the OPO5 is still part of the show.

@MrT10001 I remember that it worked by flashing it via fastboot.
Installer was never working because it was not possible to create a working ut recovery for it.

Tomorrow, the installer should work again for focal.

@MrT10001 Yes, I was testing a rootfs.img on data partition, instead of systempartition and found that it boots more stable. But it seems that, when installing it using ubports installer, something doesn't work yet.

I will rollback the change, for now.

@Scofus you can use the UT Tweak Tool from openstore.
There you need to select "apps" in the menu and then search for the gallery app.
There you can clear cache and other data of that app.

@Scofus did you already try, to clear your gallery app cache folder?

@castpixel no, the M11 is a totally different tablet.

@arcaege sure, can you please post a link here to that point in the guide?
