What else IS there?
The problem is, people are beginning to wise up to the fact that today, a phone is a phone is a phone...
I'm not really sure what else you can DO with a phone right now - cameras are exceptional, screen quality is superb, the speed of most phones is spot on, and you can do pretty much what you want on them.
Phone updates are becoming very much about pointless additions. Like the notch - as much as it pains me, Apple actually innovated a bit by sticking stuff into it. Other phones? They're simply copying as the makers somehow think we WANT a notch - that doesn't actually contain very much. But they're afraid if they DON'T add one, people will think something is missing.
I'm actually waiting for the next round of updates to have such new and innovative features like a removable battery, stereo speakers, dual sim slots as standard and a headphone socket...
