A few more random thoughts after a week with the Mate 20 pro.
Face unlock is surprisingly brilliant... seldom use the finger print scanner at all.
Enabling dev options and reducing the animation factors to 0.5 is a must.
Camera is good but not really a noticeable improvement over the U11 for general point and shoot usage. The wide angle lens and the 3x optical zoom is very welcome though.
The curved screen and general "long phone" form factor I'm not massively a fan of but theres no denying it does make it easier to hold.
Performance and battery life is excellent - really is a bloody fast phone with amazing battery life.
EMUI isnt perfect but I get on just fine with the gestures and the notification oddities seem to have settled down (though gmail notifications are still hit and miss).
Have just read the change log for the latest chinese update and it allegedly address call issues which if true is music to my ears as thats really my only serious gripe with the phone. Lets hope EE roll it out soon.
After having for a while now - pretty much sums up my experience.
2 gripes for me though - first curved phone ...so sometimes hit the curved bit of screen when picking up etc..... just a bit of getting used to I suppose.
Watching youtube videos..... I hit the stretch to full screen .... why not screens beautiful! but then you miss some details that wrap around the screen....
If I was watching certain apps the screen would dim.... Sky sports ... goal videos.... sooooooo annoying... Have turned off a setting in the developer options that may have fixed it .. will see.
Other than that best phone and battery stamina I have ever had.... dont even charge up overnight anymore - usually give it a quick juice up in the car or leave it.
