The first Gen SE? Mine was getting too slow with iOS15 with barely 5 usable tabs in Firefox before app-switching would kill them. Plus, too many apps gave up on designing for small screens so I had lots of unreachable buttons and input boxes.
I booted it yesterday, and it still has that issue where you can’t type a alphanumeric passcode on boot, because the keyboard doesn’t show up. The workaround is to click on emergency, then get back to the passcode screen.
I suspect my general usage might be a bit more basic than yours - my main apps are WhatsApp, FB Messenger, Safari, Gmail, Google Calendar, Google Maps, Spotify, YouTube and Netflix.
