If you got your Samsung Galaxy S6 / S6 Edge from a network carrier, you also got extra apps from the network which are called bloatware. Also a network locked device gets any firmware update slower than Samsung original firmwares. Also for new features like Apps Edge you need to wait longer if you are not running Samsung original firmware. To run the original firmware and get OTA faster you need to debrand Galaxy S6 / S6 Edge. This requires flashing your phone via Odin. You shouldn’t proceed if you don’t have any sort of experience on using Odin.
