Summary: I'm writing this after having had this phone for a couple years. I replaced it with a Samsung Galaxy S4 mini (great phone). I'll make the critique quick. FYI, I'm not a fan of apps, and basically use the phone for international travel, some internet, gps. 1.
Summary: Great phone, works nicely in Ecuador. At first the software had some issues and lack of customization options, but when I updated Windows 8 to it latest version most of my complaints were solved.
Summary: Windows Phone 8 was not the OS for me. I switched back to iOS after having this phone. Not being able to control the applications/OS Updates on the phone via a desktop client was a big draw back.
Pros: When this phone is working, it's great for the price. Good camera, good OS, good size and functionality.
Cons: As another reviewer stated, the buttons will inevitably stop working. And when they stop working, Nokia can't fix them but will repeatedly charge you for 'repairs'. 7 weeks and counting with this phone in 'repairs' since I bought it 9 months ago.
Summary: I received the nokia lumia 620 and it was fine, happy with my purchase until a few weeks after (less than a month) the device battery died and it refused to charge and would not turn on . I had to send it back to the seller for a full refund I was very disappointed
Summary: I love Nokia, and windows 8 is great too. But there's one single detail that made me regret this purchase: unlocked windows phones do not seem to come with "data sense", which is the only way to measure and control data usage.
Summary: Worked well initially. But too many software problems, phone kept freezing and needed to be restarted. Two things are horrendous - the signal reception and battery life. There are better phones out there!
