We've all been there before. You're reading something on your smartphone while laying down on a bed or sofa. You turn sideways, and the screen rotates. Suddenly, whatever you were reading is at 90 degrees to where it needs to be, and you're left trying to read at an awkward angle. Fortunately, we found a feature on the Galaxy Note 2 that seems to have been developed for this exact eventuality.
"Smart rotation" makes its debut on the Note 2, and like the Galaxy S3's Smart Stay, it uses a bit of front-facing camera trickery. When the phone rotates, the device uses the front-facer to work out what orientation your face is in and then match the orientation of the screen accordingly, based on the built-in sensor. That means even if you're reading at an angle, the Note 2 can recognize this and keep things the right way up. In our experience it functions pretty well, though the fact that it uses the front-facing camera means you need a little ambient light in order for it to work.
Smart Rotation is switched off by default on the Note 2, but can be enabled under Settings > Display. Perhaps not the most practical or necessary software feature ever conceived, but damned if it isn't cool.
