I sincerely hope that no one follows your advice.

The phone you point to might be a few bucks cheaper, but it has 1/2 the RAM, 1/2-1/4 internal storage, and while the MTK6589 performs surprisingly well for a Mediatek chip, it still performs below the Nexus 4's S4Pros both for CPU and GPU. The screen is also much lower res and 245ppi vs 320ppi. It doesn't have any support for LTE (Nexus 4 is flashable to Band 4) and doesn't appear to support NFC, or, probably more importantly, BT4/BTLE. There's also no front camera or a flash (!) on the back camera.

Of course, the worst thing is that it's already running an outdated (4.1.2) version of Android and is unlikely to be updated. There's a small community working on ROMs but it's sketchy (no dedicated forum on XDA, no CM port, much less an official build).

If you buy the A820, and almost all the other Shanzai'd devices, you effectively get a dead product, while w/ the Nexus 4 you'll get better hardware and both official and community support for years.

Seems like a no-brainer for a $50-100 difference.
