Summary: this product is not unlocked if you plan to use it for service that is not att you will have to pay for an unlock if you want full support. data can be accesed by seting up a new apn . but this is not an un branded unlocked phone false advertising in a big way . now I have to spend 40 bucks to unlock on my own . not cool.
Summary: Great phone... from my point of view, much better than any iphone (i had one and it was great but not that great), good sound quality (It came with "beats" sound system), fast, cool design, etc... the only drawback is the "ultra pixel" main camera, i dont think its a good camera (as the rest of specs), its a top phone but doesn't have a top main camera..
Summary: Phone came with Android 4.1.2 Jellybean pre-installed. I bought the phone in August 2013 and everything was good until I updated the operating system in June 2014. After the update, the battery started acting erratic, battery level would drop very quickly and will die when it reached 70%. When I plug the phone to charge, battery would be at 10%.
