Xiaomi's Mi Not 2 has not been getting the respect it probably deserves. After all, the phone was overshadowed and its very own launch event by Xiaomi's other new phones, the bezel-less Mi Mix. And even when the media and reporters ( including myself ) wrote about the Mi Note 2, we mentioned how much it looked like a Samsung Galaxy Note 7.
Let 's address the "Note 7 ripoff" issue first. Yes, just like Samsung's now dead phone, the Mi Note 2 has a 5.7-inch display with dual screens and curved back that meets in the middle for a perfectly symmetrical look. But it's not fair to just dismiss Xiaomi's product as copycat, Xiaomi because phonemaker was actually the first to introduce a curved glass back (before Apple did it with the Note 5). And as Hugo Barra told Engadget, there's really only one way you can do a curved screen, so this "curved front and back meet in the middle" design was just the next logical step for the company. Also, the Note 7 was introduced just two months ago - it's almost certain that Xiaomi had begun development on the Mi Note 2 already.
I've been using the Mi Note 2 for four days and much like Xiaomi's last flagship phone, the Mi 5, this is a beast of a phone with fast performance, solid build quality, great camera. And yes, while the Mi Mix is way more intriguing as a device (I'll have a review of that coming later this week too), the Mi Note 2 is probably a more usable day-to-day phone.
That's because while the Mi Mix is eye-catching, it's a concept phone in every sense of the word (more on that later in my review). The Mi Note 2, however, is like the many great flagship phones of 2016 - except it's got the latest and best Snapdragon chip, the 821. In both real world usage (like zipping between apps and editing videos via Viva Video) and benchmark testing the Mi Note 2 comes out at the top of every Android phone I've tried so far this year. Oh, and I'm on the lower tier 4GB RAM version, not the one maxed out with an extra 2GB of RAM.
(The Mi Note 2 scored a 1828 on Geek Bench's single core test and 4039 on the multi-core, that beats both the Galaxy's S7 1589/3795; Google's Pixel XL 1607/4147, but falls short of the iPhone 7 Plus' 3464 / 5688).
As I mentioned in my Mi 5reviews from earlier, Xiaomi's custom Android skins, named MIUI (now in its 8th version), is a lot cleaner than people in the west give credit for. I particularly love that it allows you to customize the phone's hard buttons. for example: the phone comes back with the assigned button to the right of the home button, but I can swap it to the left. and the home button / fingerprint sensor, although it's "clickable" like Samsung phones and iPhones older, Xiaomi gives the option to activate via touch. I much prefer this because having to press down on a physical button feels outdated in a world of touch buttons (even Apple's done away with that on the iPhone 7. Samsung phones are the only ones left).
Despite the Mi Note 2 having the same type of curve as the Note 7 / S7 Edge, I had virtually no erroneous touches on the curved screen during my four days of use. This is amazing, because I had serious problems using the S7 Edge without something accidentally tapping on the screen. I think part of this is due to the curves on the Mi Note 2 not being as drastic, and partly because MIUI's palm rejection software is just much smarter than the one on the Galaxy phones.
One of the new additions to the MIUI 8 that's very useful is the "second space" feature, which essentially partitions a portion of your phone away from the main device's hard drive, so you can store sensitive information you might not want other people to see . Much like the Note 7's Secure Folder, you can download a second copy of apps onto the second space, and it'll behave like a completely separate app from the first copy. That means you can have two Google Play accounts, WeChat or two apps (signed onto two different accounts) on the same phone. Switching back and forth between the "main" phone and the second space takes only a tap, and everything is locked via password, PIN or fingerprint scan.
Speaking of fingerprint scanning, holy crap, the sensor on the Mi Note 2 is fast. This might be the fastest fingerprint sensor I've ever used, topping even the former king, Huawei P9. It's so fast, I never see the lockscreen when I press on the sensor when the phone is in a sleeping state - it just goes straight to the home screen instantaneously.
The one area the Mi Note 2 disappoints slightly is the camera. Despite some gaudy specs ( 22.5 MP, f / 2.0), I found the photos to range from solid to good, which is not bad by any means, but the bar for smartphone photography is set so high. Here are some samples.
