Samsung Galaxy S7 was Samsung's 2016 flagship phone with very powerful hardware and the best camera at that time. Even in 2019 the phone will perform very well, however this device being already received two major Android OS upgrades, won't receive any more major upgrade.
The Samsung Galaxy S7 is still a decent phone if you're using one right now. But if you're looking to buy new, it'll be quite long in the tooth by the end of your standard two-year contract, so it pays to spend a little more now.
