In case you have an older smartphone over 3 years old, then absolutely get the new S7. I just played around with Galaxy S7 and Galaxy S7 Edge for a couple of days then my own viewpoints are derived from this.
So, first major change is the microSD memory card slot is back - now Samsung Galaxy S7 supports up to 200 GB microSD cards. But, the battery is non-removable (by the way LG G5 has a removable battery).
If you already have a last generation smartphone then you don't need to make the upgrade to S7 or S7 Edge. Smartphones are getting so standardized it can make absolutely no sense to move up and waste your money. I think, next are usually important specifications to think about whenever you purchasing a smartphone: size, weight, resolution, RAM, CPU, ROM, external memory storage, cameras ant the batttery. Anyway, for people who are using a smartphone almost all day, they can use battery power banks with high capacity, usually up to 30,000 mAh.
Buy Cheapest Samsung Galaxy S7
Also, before buying a Samsung Galaxy S7, you should take in consideration that on the markets are cheap smartphones today that are beginning to get really best for about 200 - 300 dollars (Elephone Vowney, Elephone P9000, Asus Zenfone 2 ZE551ML, Ulefone Power 4G, etc). SGS7 is supperior to any $200 - $300 smartphone, but the difference between their specs are less than double, even if Galaxy S7 is usually three times more expensive (I make team with people who say that S7 is too expensive).
Anyway, if you choose to order cheapest Galaxy S7 , then you should choose a plan from a mobile carrier, because in United States you get the S7 free, else you have to search among several popular websites to buy a factory unlocked Samsung Galaxy S7 (on amazon you can find great deals).
