Summary: I have been using this phone for 2 years, ever since it first came out. The only problem that I have had is that the original batt started to fade and I got a new one and installed it myself.
Pros: Great camera Great video Great display Plenty of storage Fast and smooth operating system Great music player Plays movies great Etc etc.
Cons: There are only 2 real cons to this phone, one is that the earpiece speaker is not very good. It works but tends to be a bit scratchy sounding at times. And the other is that the battery is "non removable"...although it can be done by taking the back off carefully.
Summary: this phone have great features and lovely camera. but I have had this phone for a few months now and placed it to charge and now is refusing to come back on. This happened with a previous one I had and just thought that one was defective.
Summary: The blue one is exclusive to ATT and so is locked to that service. I had yellow one of these over a year ago, after 11 months it had serious problems and had to be returned but that can happen to anything. I replaced it with the Lumia 1020.
Summary: I WANTED to love this phone. I switched from an iPhone after about 5 years, and was looking forward to trying the windows phone and using Cortana. While it seems to me like Cortana is more intuitive than Siri and talks more naturally, she won't do anything if you don't have service.
