Samsung isn’t afraid to experiment with gimmicks. They love to include heart rate monitors on their smartphones and have web pages scroll with the movement of your eyes. They came out first with smartwatches that take SIM cards. And now, they’ve also added a curved AMOLED display on their flagship large-screened smartphone. They call this device the Galaxy Note Edge, and it’s one of the more intriguing devices released in 2014.

The “Edge” refers to an extra, curved section of AMOLED 160 pixels wide that has been slapped on to the regular 2560×1440 Note 4 display. Occasionally it will do a few things, and you’ll feel happy you spent an extra $200 on the feature. The rest of the time it just sits there; a blank panel that turns heads because it’s so unusual. It’s a true prototype device, but one that Samsung has also put on the market to tempt consumers.

Aside from the curve, you get a Galaxy Note 4. This means there’s a Qualcomm Snapdragon 805 inside, 3 GB of RAM and 32 GB of storage. It also means there’s a 16-megapixel camera with optical image stabilization, capable of 4K recording. There’s also the S Pen, which can be used for note-taking and a range of other stuff, just like the identical pen on the Note 4.

But this isn’t the Galaxy Note 4, a device which I thought was outstanding when I reviewed it a few months ago. In fact I often wish this were the Note 4 rather than the Note Edge, for one very simple reason: the Edge itself. Its inclusion completely changes the shape, feel and usability of the device, and not for the better.
