Where to start?
iOS WiFi pickup is awful.
Scenario: Travel from one stop to another on London Piccadilly line. At each stop a (relatively) cheap Honor Android phone Wifi is connecting as the train enters the station. iPhone frequently fails to connect at all.
Replacement Screens and AppleCare
Apple charge £119 per annum for AppleCare for an iPhone and then charge £25 per screen replacement .. on the presumption that you will only require one screen change per annum. The normal 'non warranty' screen replacement is £136, which means that you are probably better off not taking out AppleCare.
iOS usage and features
Try detailing every single iOS trick and feature on your own website for once. Stop making every single feature have to be 'discovered' as if by magic by MacWorld or any other fanboy websites.
iCloud Synchronisation with Windows
Yes, some people really do own a Windows computer AND an iPhone. Once they have got over the shock perhaps Apple might do something in iCloud like tell people, "Oh, by the way Two Factor Auth does not work with Windows, so your contacts and calendar might not be in sync on Outlook"
I could go on and on ad nauseam.
