When you thinking about smartphone you will think iPhone6s and Samsung Galaxy S7. Samsung Galaxy S7 is the most popular in South Korea and IPhone6s is the most popular in west. The Galaxy S7 was the prettiest phone Samsung's ever made by quite some margin. IPhone6s is slim more than Samsung Galaxy S7 but Samsung Galaxy S7 is lighter than IPhone6s. The camera in the iPhone 6S Plus is no slouch, of course. But it has a smaller pixel size than the Samsung device, as well as an f/2.2 lens, meaning it won’t let in as much light and consequently won’t be the best for low-light situations. it has a battery capacity of 3,600mAh, which is a bit more than the iPhone’s 2,915mAh capacity. iPhone 6S has some (unofficial) water resistance, but the Galaxy S7 fully lives up to its claims of surviving full submersion for up to an hour in 1.5m of water.
