The S7 is the phone to beat. It's predecessors have all been the most popular Android phones on the planet when they launched, and the S7 is no different. Between the killer screen, camera, and design...the Galaxy S7 is always at the top of the pack.
Specs
Pros
Pro Expandable storage
The Galaxy S7 has brought back the SD card slot (the Galaxy S6 didn't have the slot), which allows for 2TB of theoretical storage. The only problem is the largest micro SD card on the market currently is 200GB, but that's still a lot of storage. Because there is a SD card slot, you can add more storage after buying the phone - something not all phones offer.
Pro Industry leading camera
The camera may only be rated at 12MP, but it uses 'dual-pixel' technology which means there are actually two sub-pixels for each pixel. These dual-pixels will be able to capture much more detail than a regular 12MP camera. Each pixel has also been enlarged, allowing more light to enter. This means that lowlight photography will be drastically improved.
Pro Fast performance
In America the S7 uses the Snapdragon 820 processor, the worldwide edition uses the Exynos 8890. Both of these processors are brand new as of 2016, and will offer great performance for years to come.
The Exynos version is about 10% faster when it comes to loading apps, and performs 44% better when loading recent apps
Pro VR available
The Galaxy S7 is compatible with Samsung Gear VR. It costs $99, but sometimes can be bundled with the phone for less. It is a great affordable introduction to virtual reality, although it isn't the best solution available.
The phone clips into the headset, and connects via the USB port to act as the brains and display for the unit.
Pro Fantastic display
The 5.1" 1440p Amoled display is the best display ever put on a phone. The Amoled display technology allows individual pixels to turn off (IPS LCDs have the whole backlight either fully on or fully off which is why they still produce light on a totally black image), meaning that black colors truly are black. Colors appear to pop out of the display as well.
Older generation Amoled panels used to suffer from screen burn-in, however this issue was addressed last year and should no longer cause any issues.
Cons
Con Battery life is not that great
Although it's not a small battery, and it charges really fast with a fast charge, you get the feeling it won't last a full day. Having to disable a lot of stuff to get through the day, especially if you are going out at night can be a compromise many do not want to make.
