Fairphone 4
FP4
Updated from /e/OS 1.18-s to 1.19.1-s
Not rooted
Had to do two updates, first to 1.19.1-s-20240110??? and then to 1.19.1-s-202401103272023-stable-FP4
Up to now no issues besides the non-working search function in calendar (crashes the same way as in 1.18.s). EMail seems also to work.
Thanks to the devs again!
