The first round of 2016 Android flagships are all out in the open, and that means you've got a serious decision to make if the time has come for an upgrade. The best Android phones are priced near or over $700, so you don't want to make the wrong decision. That's a lot of coin to spend on a phone if you don't like it. Samsung was the undisputed winner last month on the carrier side, but this month the HTC 10 is up for preorder.
The Galaxy S7 has a very similar overall aesthetic to the Galaxy S6, but it makes several important changes. It's not a revolutionary device, but it really focuses on the GS6's shortcomings. There will be deals on the GS6, but don't let the similar looks fool you. The GS7 is a much better phone and it's worth the cost.
Samsung is using a metal and glass unibody design for the GS7. So yes, that means fingerprints and the potential of a cracked back if you drop the GS7. The designers took an unusual step, though. Samsung made the GS7 about a millimeter thicker so the camera hump is flush with the back, and there's more room inside for a bigger battery. The glass panel on the back also has curved edges to make it more comfortable in your hand.
The slightly thicker frame means the regular GS7 has a 3000mAh battery, and the GS7 Edge has 3600mAh. Both phones are also water resistant, which is a feature Samsung dropped from the GS6. There's also a microSD card slot in these phones, another improvement over the Galaxy S6, but it doesn't support adoptable storage in Android 6.0.
The Galaxy S7 and S7 Edge have new Super AMOLED panels with the same 1440p resolution as last year. The GS7 is 5.1-inches, while the Edge variant has a larger 5.5-inch display. The Edge, of course, has a screen that curves down on the left and right edge. I don't think the Edge is as comfortable because of the narrower band around the screen. There are a few software features that are intended to take advantage of the curved panel, but none of them are necessary. The real reason to get this version of the device is that it looks really cool.
