My P20 Pro still mention EMUI 9.0 is latest version.

Do I need to login HiCare to get latest updates?

Thanks, managed to update using HiCare. Didn't use it earlier since I don't have to use HiCare to update my Nova 2i previously.

If only Huawei allow unlocking of their bootloader for their devices and custom ROMs (I know they once did, but that route is closed), quite satisfied with P20 Pro even though it is lacking a super wide angle camera, with 6GB RAM it should still be quite usable for sometime.

It's not so clear vs other better camera modules (more current ones) out there. I knew I was not fully satisfied with the camera when I first got the phone (it can't really compete with SLRs or even the mirrorless cams) but what I wanted was 3x optical zoom for me to take slides in a presentation and it does its job well and night mode is good enough.

The thing about the picture like coloured pencil or crayon has been there since day one - I suspect is the phone using the B&W sensor and then using another camera sensor to artificially fill in the colours - not only at 3x zoom. You can see the perspective/picture shift a bit when the colours change from the vivid one to the not so vivid/crayon like - it's the change in camera modules being used to take the picture.
