Lock screen widget is a must. Maybe they can reintroduce Galaxy Apps with more sections such as Widgets, better themes, sharing Bixby routines with Others.
I wish also they add more actions for Bixby routines and let developers implement it in their apps like Tasker and Siri shortcuts in iOS.
If they make the bezel narrower, and better battery/camera.
I've been using samsung since original Galaxy. I used iPhone/pixel also and I always came back to Samsung for my own reasons.
Now I'm using Galaxy S23, I switched from the S23 Ultra. The only reason I got this device because I want a compact mobile device.
The device isn't out yet and we're not sure about the specifications, but I'm sure that buying used/last year flagship is much better than these e-waste phone.
