No CarPlay is a dealbreaker for me.

So easy to do with 4 digit PINs. Mine’s a lot more and I can put it in so quickly, short of videoing me, nobody’s going to successfully observe me.

I know it’s not what you want to hear, but almost certainly no. I would be quite worried if it were possible.

Face ID works excellently for me. It’s not too fussy about angles, or the fact that my face can change from full beard to clean shaven, or be anything in between. With or without glasses or sunglasses not a problem either. I prefer it to fingerprint, but I never had a problem with that apart from it being inconvenient if wearing gloves.

Same here. Excellent choice

It’s often stated that the lower processing power, memory, storage and other hardware would make it unusable.

Why is it an issue? You have loads of space left on there. If you were running out of space I’d understand. I wouldn’t worry about it until then.

Xs 4 years. Immaculate condition - my wife has it now after I replaced the battery for her when I got my 14Pro.

It just copies it rather than deleting it. Can’t answer the WhatsApp question though.

It’s still going to take a long time for everyone using physical SIMs to move to new phones. Loads of people I know are using 5+ year old phones with no intention of getting a new one until it breaks. There’s still a large market for non-smartphones and other devices like mobile routers, cameras etc. that need a SIM card. These don’t get replaced anywhere near as frequently as smartphones. My last mobile router lasted 5 years and I expect my new one to as well.

Physical SIMs will be around for a long time yet. I don’t think it’s anything to worry about. Plenty of people are using older phones with no thought of updating. There are over 6 billion smartphones in use and probably at least the same that aren’t smartphones.
