very preliminary; given that according to the saying on UT radio, your device is the same as mine (Fairphone 5) it may be a total surprise that it works.
Preliminary remarks;
I launched the switch from ssh as is usual for me, when I realized that it was not merely doing a switch but really downloading the thing, I promptly aborted and restarted from the terminal
after the download was complete, I got an error message and an invitation to look at the 'log'. I have no idea where is this wonderful log, though.
I restarted the phone then restarted the system-image-cli with full logging this time, however tt has already downloaded everything and restarted the phone after a few seconds as it was probably supposed to do the first time.
From there it was the usual install phase, for my sufferings I got a magnificent intro page that I skipped immediately, and the normal UT shell appeared.
First impression: feels a bit snappier.
Don't work: the 'advanced' browsers other than Morph don't work well, Min from @pparent crahsed immediately, and uWolf started and displayed a page, but no OSK. This is not very surprising. The piano from @pparent don't start anymore, not surprising - but what will say my niece when she will ask for my phone next time I'll see her ? This is a priority
Constation: the kernel is the same as before, and (correlatively) systemd is the same version as Ubuntu 24.04 (255 while Ubuntu 26.04 as 259). This was expected as well since systemd 259 is not compatible anymore with 'old' kernels like the FP5 one.
Was not working with 24.04-1.3 and works with 26.04: Bluetooth pairing. Sadly my Bluetooth keyboard now connects, but don't seem able to actually provide any key input to the terminal.
Dekko works, wifi works, phone calls, installing a click from the store work as before.
That's all for now, I'll go out now and it will be an occasion to test GPS a bit
