I only got it today so I've had around 12 hours with it. I guess my first impresions are:
Pros:
+ Really nice design, solid hardware, looks and feels great.
+ Software is really snappy, smooth, pressing the wifi icon in the notification shade actually turns on/off the wifi, rather than bringing up other menus...
+ Oustanding screen. Comparing the screen to my Pixel 6 Pro is night and day, the S22U screen is miles ahead. And like 30% brightness on the S22U is equal to the max brightness on the P6P.
+ Fingerprint scanner is excellent. Instantaneous and extremely accruate. Again, come from P6P, this is so relieving.
+ So far reception has been rock solid and I haven't run into any bugs yet.
+ Camera looks to be really quite solid again.
Cons:
- Vibration motor doesn't feel as good as P6P. Just doesn't feel as strong. I have vibration on for typing and it's just not as nice, feels weaker for typing and when I get calls.
- Battery *might* be a bit dubious. Only day 1, but I feel it drains a little faster than I'd like. Not as quick as the P6P so far, but from memory the S21U had better battery life? Will have to wait a few days/week for the battery to calibrate and get proper readings though.
