The main ones for me are:
- Putting the front camera and sensors under the display or in a much smaller cut out than the current implementation
- Offering an alternative way to unlock the phone, ideally Touch ID in the Power button
- Providing a more competitive level of optical zoom, maybe 10x or something similar
- Higher transfer rates for getting photos and videos off the device, at least make it utilize USB 3.x speeds
That‘s about it, really. I‘m still very happy with my 13 Pro, in many ways it‘s fantastic. It‘s just a bunch of little things that you sometimes wish you had.
