Huawei just did what Samsung couldn't

It's also the first phone with PCM microcapsules for cooling that absorb heat and become in a liquid state, or the first one with two finger scanners, one embedded into the display. Wait, what? Yes, the Mate RS offers a way to unlock the phone with your fingerprint both at the front, and on the back, and both scanners are situated right under your thumb or index finger, respectively, without having to do yoga and stretching exercises down to the bottom of a big-screen phone. What's more, it "allows consumers to wake up the device by floating their finger above the display, while touching the sensor to unlock the device is lightning fast. The back fingerprint sensor can also be used to unlock the device or to access a second, secure space." Cool beanies.

That anywhere-on-display scanner used to be considered the Holy Grail of fingerprint scanning, and we just previewed a crude version of it at the MWC expo in the beginning of the month on a concept phone. Well, it is now appearing in a retail device, with a high-res OLED display - something that reports said Samsung struggled for the last year or two to implement. We expected one in the Galaxy S9, and it didn't materialize. 

The Note 9 in-screen fingerprint scanner rumors are on and off, as the technology is apparently "challenging," "expensive," "doesn't work with screen protectors," and so on. Well, while it certainly isn't in an affordable phone, Huawei just pulled it off, and with a ergonomics twist at that, so we can only hope that Samsung will master it, too, by the time the Note 9 ships. After all, it will also be a niche device, and, judging from its predecessor, is unlikely to come cheap.
