I don't get why you'd want a smaller phone unless you're looking to get one in a flip-phone style form factor. I'd be down for that. I miss being able to accurately text from my pocket.
Being able to hold the phone comfortably and securely in your hand is really important for me. I'd love to be able to reach the vast majority of the screen without having to shuffle the phone in my hand or use two hands. I very rarely watch any videos on my phone, or play any games that require a large screen.
One-handed mode exists if you need to reach the whole area of the interface with one hand, albeit it won't help if grip is an issue. Maybe a pop socket kinda thing for that?
Ok? The issue wasn't clearly defined. There's always pop sockets and similar to make it easier to hold. That said, my teenaged kids have 0 be issue holding this phone so idk what OP is on about
Never really felt my phone was too big, though there are times where I've got a show to go to and wish I had a cheap flip phone to fall back on. The older phones seemed fine at the time until I realized how much better the bigger screens were. I'm not sure I'd want one bigger than the S23 Ultra, unless it folded out to a tablet.
