I bought this to replace my Galaxy S7 Edge and I've been very happy with it. It's little bit taller than my S7, but not much wider or heavier. The screen is very good, though not quite as vibrant as the Samsung. The phone is plenty snappy and will handle anything I want to do easily (note that I am not a gamer). I have service through AT&T, and I was able to just pop my sim card in everything worked fine without having to adjust any settings.Huawei uses its own version of Android (EMUI), but it's not nearly as intrusive or annoying as the software on my Samsung. (This was a major reason I didn't want to buy another Samsung.) I use a custom launcher from Microsoft and the phone handles this just fine. It's easy to use Google's own apps for just about everything other than the phone dialer, and it doesn't come preloaded with a bunch of junk.The camera: This is the primary reason for buying this phone. The camera has three lenses on the back, and it takes fantastic photos. The default mode uses some AI processing to figure out what you're shooting and adjust the settings accordingly. (See the attached pic of a spider in the garden. TW: It's a spider!) Most of the time it gets it exactly right, but sometimes playing around with the settings helps. It also has a night mode that will take continuous exposures for four seconds, and then the AI stitches them together into one image. The results are amazing (see the attached night shot). The photos actually end up looking much brighter than how they appear with the naked eye, so it's kinda sorta like night vision. The zoom feature also works really well, at least in daylight. All of the reviews praising this phone for its camera are right. I don't know much about photography, I just know that I get even better pics from this phone than I did with my Samsung, and I was really impressed with that.The battery: It's big, and it lasts all day and often fairly far into the next day. This phone has three modes of charging: regular, fast, and super. Super only works when you use the supplied charger from Huawei, and it's really fast. However, the phone also supports fast charging with the Power Delivery (PD) standard if you're using a type C-to-type C charger and cord. This means it will show "fast" charging when I use third-party PD chargers (I have one from Aukey that I use for my laptop). And while "fast" charging isn't as fast as "super" charging, it's fast enough. When I plug this into my QC 2.0 or 3.0 charger using a type A-to-type C cord, it just shows regular charging. So the bottom line is that the Huawei proprietary system is best, but you can also buy generic PD charges and it will work just fine.Odds and ends: The fingerprint reader is super fast. Audio through the included type C adapter (on admittedly cheap headphones) is good and plenty loud. A screen protector is already on the phone out of the box, which is really nice (although it does tend to get smudged easily). I ordered a Spigen rugged armor case, which fits great and offers good protection.Problems? Nothing significant. I miss the headphone jack and wireless charging. With this nice of a camera I wish it also had a dedicated camera button on the side. Looking forward to Android 9. (It arrived running 8.0 and immediately updated to 8.1.)
