Upgraded form the S4, I really like the performance of the S6. Took a few minutes to get use to the system but it didn't take long. This phone will do more than I will probably need it to do, but it's nice to know that the capability's are there.
It is a nice phone. It has been freezing up on me though. Also, when I'm on the phone and not on WiFi it won't let me use apps Like maps or anything. This is so frustrating. It was fixed for a while by choosing advanced calling but started doing it again. It has also started to slow down a bit. Also, the contacts section could use some help.
