My first observations:
+Great camera - especially zoom one!
+video is better
+Has double tap to wake up, boy how I missed this I disabled it - too many self unlocks
+UFS 3 is a lot faster internal storage than 2 on P30 - downloading pictures is 2x faster over WiFi
-the screen is a bit darker than P30's?
-this huge cutout on a screen for useless (for me!) 3D camera
-has pre-applied screen protector I removed it and now is fine
-The wide camera is 18mm instead of 16mm in P30 Pro
- battery last shorter time
more + and - will come as I use it from 5 h
Now about missing services - phone clone app is by far the best cloning solution I ever used - in 5 minutes I had an almost exact copy of my P30!!! Minus Google Chrome and something else, I can't remember I miss Chrome but for now, with some minor hiccups, FireFox is filling the gap! Chrome is the best I installed it
All apps I use are up and running for the moment - future updates I need to figure it out how to backup calendar? - The internal backup app is doing the job remain to be seen restore if needed
In General, I am happy with it, only time can prove me wrong
