@martinvermeer Sadly, Sailfish isn't fully open source. Some bits are open, but other parts are closed source, especially in the UI layer and built-in apps.
I'm a Jolla daily user since the original Jolla 1. On my 4th device now (Xperia 10 iii). I like it a lot, but it's not without its problems. I hope that this 2026 phone will give the Jolla developers resources to make the OS even better to match mainstream expectations.
