It is said that 640 LTE DS is supported only by the 410th snapdragon c Adreno 306. This does not add performance, but already supports the 64-bit architecture. It's right?

I have a little black. The screen is super, but the back cover is pretty, not a soft touch, but some kind of rough plastic.
Question to the owners -
Was the box in the film? Was there a film on the phone on the screen?
And yet, I can’t select this phone as the main one in the profile settings due to its absence in the list, correct it!

Rep: (19)
How to build?

It is assembled perfectly, everything is tight, elastic, without gaps and backlashes. Assembly Vietnamese, Accum Chinese. Compared to NL720 where 512 mb, 640 with gig of RAM just flies, the lumiya camera opens instantly. Product code can current look in the evening.
The camera at first glance seems to be nothing, either, until I experienced it.

I was embarrassed by this too, there are no films, and the sticker was painfully easily peeled off. And the bag with the battery was open. Although it may be checked before shipping.

All right, I ordered a blue with two SIM cards at a corporate discount, 8791 rubles came out.
Here I look at the truth that there are no films on it or any covers on it at all.
And yes. Having here already devices on hands, lay out photos of the device itself, plus take photos in different conditions and add here.
