It seems that there are several issues with the current Sailfish OS release. To name the most often mentioned issues in order of severity: - OS update process issues (blocker) - general stability issues (critical) - missing features and stability issues in WLAN connectivity (major) - e-mail syncing issues (major) - missing features and bugs within built-in browser (major) - incomplete support for MS ActiveSync (important) - incomplete Android app support (important) - etc. In my mind, Jolla should stop developing new features (MMS, portrait mode, 4G etc.) for time being and concentrate all efforts on getting the current features complete and all the bugs rooted out. Judging on the shear number of reported bugs and missing features, I would think Jolla needs half a year to fix the OS, then release a true "beta" version next summer and test that for a couple of months, and have a stable "1.0" release next autumn.
