Some of these bugs are more well known but for some like AirDrop not working or hotspot not connecting I always thought “well it’s probably because some power setting / DNS config / ad blocker / whatever” that I accidentally changed from the default years ago.

Nostalgia is real but I do remember a not so distant past (around iPhone 4S or so) where AirDrop worked, autocorrect worked, text selection was flawed but predictable, WiFi connected and stayed connected etc.

What happened?
