I moved up from an S3 to the S6 and what a difference. This is a great phone with excellent battery life. I cold not go a full day with my old phone under normal conditions and this one last so much longer. I like the security features (IE: Fingerprint scanner). Nice design and feels like a solid phone, not flimsy.
I had an S6 using Sprint Service. It will not stay on a call. It dropped every I made using it. If someone called me the phone would go straight to voice mail battery. Apps would not open giving error messages all the time or force close. The battery would last little more than 4 hours needing be charged constantly. You can not talk on the S6 and make use of data i.e. internet at the same time, a step backwards in technology from the S4 it was replacing. The phone has way to many bugs on the Sprint network to be of any use, fist and foremost a phone must perform as a phone and the Sprint Samsung Galaxy S6 was not doing so. When I called Sprint the rep told me to return the phone while i was still within the 14 day return period, they had not fix date in sight. As pretty as it was, as nice as it felt the phone was useless on the Sprint network for me. Did I like anything about the phone, sure; Lollypop was fast and smooth, no stutter or lag at all like with the S4. The built in wireless charging is a nice touch but none of that matters as the phone is so buggy it cant be used. I never got to fully play with the new camera so I cant type on that but if your a Sprint customer don't take my word for it, goto the Sprint website and look at their community site and ALL the complaints just like mine on the S6 dropping calls, apps not working correctly, battery drains and terrible connectivity and slow speeds. I don't know if its Sprint, lollypop or both but steer away from the phone for a while to see if Samsung or Sprint can get it working correctly.
Pros: Bright display
Cons: Did not meet expectations, drops calls battery drains fast slow conections, apps not working, very buggy on sprint.
I love this phone and would not trade it for any other phone. I have been a Galaxy fan and owner for years and won't switch. My only advice is to keep a charger handy at all times. The battery life is depleted very quickly.
I have had 3 Samsung smartphones, the fascinate, S3, and now the S6. (My wife has the Note 3). All I can say I have liked all of them and each one better than the last. Great camera, fast processor, a lot of things changed some better,some not, but I love it.
