Xiaomi Redmi Note 2 - Real PDAF ? What is the camera sensor used ?

Hi,

I own a Xiaomi Redmi Note 2 Prime, recently, there was a review of this smartphone here:

http://connect.dpreview.com/post/9504161465/xiaomi-redmi-note2-quick-review

And I was wondering, how can I identify the Camera Sensors on this phone?

There has been a teardown of the phone, and below is the picture of the sensors found:

The thing is, this references don't lead to anywhere... I've searched the net for them and found nothing... On Xiaomi's publicity, sometimes the sensor is publicized as being from Samsung or OV (Omnivision), this is never good, as we never know really what is the sensor we have on our phone...

And I've seen my share of Chinese Smartphone manufacturers that say they put sensors from Sony, and then it's Omnivision or Samsung (if your lucky), or else it's "Sunny" or some other small time chinese sensor brand...

What called my attention was, that for a smartphone so "cheap" (base model costs aprox. $125 in China), they put a 13Mpx PDAF sensor on it...

But I'm not sure both Omnivision and Samsung produce sensors with the same specs, also, from the picture below, it looks like the sensor might in fact be from "O-Film", another relatively lesser known sensor brand (check: http://www.o-film.com/View.aspx?ClassID=4&NewsID=61)

Both sensors seem to have similar codes:

OMI BA08

OMI 5F05

So it looks like they might be sourced from the same manufacturer, but looking at the references, I'm afraid if they aren't really a 8Mpx sensor, interpolated to 13Mpx... Because of the "08" in the reference of the back sensor, while the front one has "05" which corresponds to the frontal camera spec of 5Mpx.

Can anyone help me identify the real sensor inside my phone? Thanks for the help !
