It will not surprise you to learn that the Lumia 620 does not reveal anything earth shattering. Of the Windows Phone 8 devices, this is colorful and affordable device offering the "Nokia experience" that all Lumias apart from the other Windows Phone 8 devices. Things are rather well organized, just like its two bigger cousins. The tear down follows WindowsMania’s normal method. The display has two distinct parts, presumably to make it easier to replace parts if something breaks. One might take note of the dual microphone set-up as well.
Since none of us are in the habit of disassembling our devices, it is always interesting to see what is inside. Be sure to zoom in on the pictures to see more detail where you can.
