The "twilight" colour isn't mentioned in this article, and it's quite unique. It really makes the phone stand out.
The application drawer is configurable. Yes by default it's off but it's just a simple setting to turn it back on.
The camera has some very big features which aren't mentioned here. There's the 5x hybrid zoom which is just about lossless. The wide aperture mode is really well done - it's both flexible in terms of the focus point, and the aperture itself is configurable. Including after the shot is taken.
The Bluetooth connectivity includes LDAC and AptX, unlike the iPhone, so at least that takes away some of the sting of not having a headphone jack.
The battery, according to all the reviews I read, is a solid 2+ days. I get a full day of relatively heavy use out of my X but two days is not possible.
In my opinion the camera is far superior to the X's. I used it and I'm impressed. It's not like the 4k@60 is actually useful for most people. I just upload to YouTube (clips of my son mostly) and they come out 1080@30, so there you go. No idea how to make it keep them at least at 4k, and I doubt it even supports 60fps.
I'm not that keen on the bottom fingerprint reader in the P20 Pro (the P9 had a much better placement), but overall the design is every bit as nice as the iPhone X. In fact the only thing hardware-wise the X does better than the P20 Pro is in the speaker department.
Now I'm sorry I didn't wait for it. I thought that Huawei will come up with a slightly nicer P10 (which wasn't so impressive), but they've really exceeded my expectations with this one. If you wait for 2-3 months you'll even get it for reasonable money.
I think 8/10 is a bit stingy. It's one of the best (if not the very best) Android flagships out there.
