I have rage-quit apple for a C2 and the muscle memory still kicks in after months. The ergonomy of Sailfish is sometimes bizarre, the little top left dot for navigation for example. Still it does everything I need, just with a very bad camera. Let's hope the 2026 will fix that.
Oh but you don't usually need to care for the dot itself so much as it's just an indicator that you can do a middle swipe left/right to move between stacked pages.
I've been on Apple for a couple of years after a decade on Android and I still haven't internalized all of iOS's inconsistencies. But admittedly I don't do much on my phone besides SMS, calendar, and maps, so using other apps is always a bit of initial relearning.
