In my opinion the Samsung Galaxy S7 edge is the best smartphone from the Samsung company. It's camera is amazing, the camera of Samsung Galaxy S7 and S7 edge is almost like the DSLR cnaera. It was the world's first phone which has an aperture of 1.7 which means you can take the photos very quickly and in low light the photo look like there is a lot of light. It has also dual pixel technology which means the photo comes as like when you see with your own eyes and the best part I like is that the phone has Valcan API chipset which means you can get almost the PC like graphics in your mobile.
In this phone you have an expandable memory. You don't need to ask about the performance I mean the Ram and the processesor. There are two chipsets of version 1 is Samsung Exynos chipset and than other is Qualcomm Snapdragon chipset. Samsung Exynos chipset is the best chipset in the market till now because it has 14 Micron technology and the Qualcomm Snapdragon 820 which is the latest chipset from the Qualcomm has almost 20 Micron or 16 Micron. The lesser Micron you have the better performance you got.
And this is my review friends thank you if you have any doubt please comment then I will answer for your questions.
