Indeed... mail is still buggy too: not showing any messages or blanc boxes for 30 seconds from the start. Touching a message sometimes opens a different message.

@telefono confirmed: Calendar is a mess. Not a clear and uncluttered view and like mail, touch one event and iOS opens a different one. After selecting the right date, adding a new event still gets the wrong date. I always have to correct it, because it selects one or two days before or after. Very annoying.
The touch screen still randomly becomes unresponsive. Still have to lock & unlock the iPhone to temporarily fix this.
Also, the iPod function (playing audio through a docking interface) has become unstable. Connecting my SE 2018 to my car iPod dock worked in 14.2, but now only after reset and only if no playlist was playing before. If I start a playlist with Shortcuts, it completely goes silent and after 5-10 minutes stutter and digital rubbish comes from the speakers.
The HomeKit panel is blanc at first start. I have to close it and reopen it to make it work. Issue existed from 14.0
Sometimes the Home app needs a restart to fix it.
Bluetooth is still a battery drain, strange but true. Issue existed since iOS 13.x even before I purchased some Eve BT homekit devices. I have to turn BT off for most of the time.
One plus though... finally we have 25fps recording.
But for some odd reason you need to flip a switch first to show that new option, labeled "PAL structures".
@Apple programmers, as a television broadcast engineer I have to comment on that:
"PAL" is a acronym of a analogue standard for encoding colour in analogue video. The frame rate being used has nothing to do with it. "PAL" video is also used for 29,97fps analogue video, in Brazil for example. On top of that, most European countries have abandoned analogue television for years now.
Now I know lots of people still use terms "PAL" and "NTSC" even though all their video equipment is fully digital and HD. But still, it is good practice to use the correct terminology with the actual technology in use. Lose that switch and just add all the world standard frame rates in one list.
