@MrT10001 Found it. It's the Sapot browser - don't know why. Every other app gives sufficient sound, including the Morph browser. "Man findet es immer da, wo man zuletzt sucht" - German saying, meaning "you always find it where you are looking last" (deepl). Thanks again.

I will mark this as "solved" though the "problem" wasn't a problem and didn't need to be solved. Sorry for the fuss.

@muskist That's nice to hear

@beyolf Fairphone 3 running 20.04. OTA-2

In case somebody arrives here with not changeable scaling issues, I want to add another solution: If you have the file ~/.config/systemd/user/lomiri-full-greeter.service.d/override.conf, it may look like this: [Service] ExecStartPre=/usr/bin/dbus-update-activation-environment --systemd GRID_UNIT_PX=21 It overrides the deviceinfo value of GRID_UNIT_PX. You could remove the override or adjust it to your needs.

@kugiigi Thanks! Worked out fine!

@Keneda Thanks!

@keneda "Best" reason is the forum rules. Where can I find them? TIA

Thank you!

I like it

@Luksus thank you Luksus. I was hopeful because it's the next release from lenovo and has a gorgeous screen

@ruditimmer Can't find that one. Anyway, thanks! I'll mark this solved.

@applee Fine solution ! Pulsar33

@muskist nice. Ok, the fastboot -w command did definitely work for me... but who knows. There is another command fastboot format:ext4 userdata which should also work, but I have had the impression, that the -w command made my device boot more reliable... Perhaps "-w" does work only after formatting with ext4? Anyway, nice that it is working now.
