OnePlus 3 is now official: 5.5" phone with Snapdragon 820, 6GB of RAM and premium body for just $400

The OnePlus 3 features a Snapdragon 820 system chip with 6GB of RAM, and it comes with a whopping 64GB of internal storage (but no microSD card expansion option).

Here is a quick look at the specs:

The OnePlus 3 features a 16MP rear cam with the Sony IMX 298 sensor and sporting a 1.12μm pixel. The sensor features phase-detection auto-focus for faster lock of focus, as well as optical and electronic image stabilization that should combine for more stable footage. The lens on top is an f/2.0 one. The main camera also supports 4K video at 30 fps, as well as slow motion at 720p and 120 fps.

This is all just tech talk: what users want to really know about, though, is camera quality. While we're yet to test that, OnePlus has published some official camera samples from the OnePlus 3 for consumers to check out and they look quite amazing. Note that the camera also features an auto HDR mode, as well as a new de-noising algorithm for sharper, smoother detail.

The OnePlus 3 will come in three models: one aimed at the United States and the North American market in general, another one for Europe, and a third one for the Chinese market.

The US version of the OnePlus 3 supports 4G LTE bands 1, 2, 4, 5, 7, 8, 12, and 17. This covers AT&T and T-Mobile's bands, plus it also covers band 2 and 4 used by Verizon Wireless, but not its main band 13. There is no support for Sprint's 4G LTE bands. Take a look at the bands US carriers use and which ones they rely on the most in our 4G LTE cheat sheet.

The European model supports 4G LTE bands 1, 3, 5, 7, 8 and 20, so you should be all covered, and that's in fact the same band support as needed for Asian markets outside of China.
