OS updates are paywalled (subscription)
This, at least for the C2, has changed https://forum.sailfishos.org/t/long-term-sailfish-os-updates-free-of-charge-for-all-jolla-c2/23491 (likely because it's conflicting with EU law), and they've instead introduced a Voluntary Subscription.
Honestly, I rather pay for my OS than paying for it with my data / privacy or living in an ad-infested garbage fest.
+1 for Gapless. My library is not nearly as large, but it's still plenty quick (no noticeable delay) with my 1 digit gigabytes library and IMHO the best native feeling media player on Phosh/GNOME Mobile.
It also does the Album -> Artist -> Song thing (which made me notice that I still have not fixed every error in metadata I managed to add to a part of my Library by blindly applying musicbraiz suggestions via Tagger, but that's just a me thing).
It's not a font ... and it says LINMOB (for LINux on MOBile).
I drew it in GIMP ages ago (15 years maybe?); and did not have the time to come up with a new logo since. (I am not super happy with it myself - but it's not a priority, there's way more important stuff I don't have time for).
That said: Contributions welcome! (at https://framagit.org/linmob/linmob.frama.io)
This is great, even if at least one app in that collection is only available for x86_64, which makes it hard to actually run on a phone ;-) They also updated the Device Support section of metainfo guidelines: https://docs.flathub.org/docs/for-app-authors/metainfo-guidelines/#device-support . Looks like some apps on the KDE side still need proper metainfo to show up: https://invent.kde.org/teams/flathub/issues/-/issues/34
See https://linuxphoneapps.org/categories/conference-companion/ - both Confy and Kongress are decent. And then there's a relict from N900 times: https://flathub.org/en/apps/at.priv.toastfreeware.ConfClerk
