(2015 Sep) a new sensor chip + NVT8417 companion chip (dated 2014).
The resolution seems to be still 508 dpi, but looks like it is not a square chip: 112x96 pixels
(I am unsure if I'm still able to properly count pixels, that's weird numbers...), so a little bit better than the previous version.

of Qualcomm® Snapdragon Sense™ ID 3D Fingerprint Technology.
It seems there are two demos at the MWC2015: a regular sensor, and the same(?) below a glass, to demonstrate
the ability of capturing fingerprint through the display glass. In the last case, the image is becoming very noisy
(this is maybe the reason why there is the logos on screen?). 3D image, they said... check out Vkansee to compare.
It seems that dry fingers are still a problem...

|
|
|
(2014 Apr): Chipworks tears down the Galaxy S5:
confirms this is a Synaptics/Validity chip inside.
It seems that the metallic border of the button is used as a ground or signal line, likely
useful for the sensor itself.
So there is the Validity chip on a flex -as usual-, but this time there are balls to go
to the upper part of the button: it is likely that the conductive lines are directly done
on the inside part of the button. I wonder about the number of "pixels", because the number
of balls is pretty low, so likely a not so good resolution...
Let's call this chip the VAL004A8 :) Take care of the die mark, dated 2008, which is confusing...
|
|
(2015 Mar): Synaptics announces
the expansion of its Natural ID™ family
of solutions with mass production of its small area touch sensor

Year (2003) on the photo is surprising. Likely an old photo.
The Natural ID family as shown at MWC2015: FS4300, VFS6100, VFS7500.
Synaptics is proposing "Match-on-sensor" (via Planet Biometrics)

formerly known as Shenzhen Huiding Technology Co. Ltd.,
introduces a new active capacitance fingerprint sensor.
Goodix presentation (OFweek).

sapphire cover and sensor into a small volume.
The mode of operation is similar with Apple Touch ID technology.
Products: GF6616, GF6626, GF6610 and GF6620. Minimum size is only 9.76mm x7.4mm x1.17mm.

Vkansee
(2015 Jan) Vkansee formally released UTFIS,
an ultra-thin optical fingerprint sensor, at the CES.
UTFIS uses advanced pinhole imaging techniques to take a high-resolution image
that requires neither a lens system nor a prism for reflecting the light.
2000dpi, 1.5mm thick, size: 11,25 × 7 mm (TBC), 8x12 pinholes
Announces that a fake finger can spoof an Apple Touch ID sensor
(not a big deal), but not their sensor
(it would be better to stay humble on that subject...),
thanks to the third level features (pores).
See the sensor working on this video from mobiwatchEN
See the sensor working on this video from CNET, with a
not so contrasted image, likely from a dry finger (bad luck, guys).
