Synaptics announces mass production with a "top five OEM" of the Clear ID FS9500 family of optical in-display fingerprint sensors-- a vendor Forbes reveals is no other than Vivo.

The Synaptics sensors promise "one-touch high-resolution scanning through full cover glass." They should enable button-free, bezel-free infinity displays, and since the sensor is covered by glass it operates with wet, dry and cold fingers. In addition, Synaptics claims the sensor is "twice as fast" as 3D facial recognition, and requires just one touch to operate.

On the security front, the sensors carry a range of authentication technologies, such as Quantum Matcher (for adaptive fingerprint template matching and authentication), PurePrint (anti-spoof technology) and SecureLink (combines support for TLS protocol with ECC authentication and AES encryption).

Qualcomm announces the next generation of flagship Snapdragon mobile processor-- the Snapdragon 845, a direct successor to the 835 with features including 4K HDR video capture at up to 60fps.

The Snapdragon 845 combines a 2.8GHz 8-core Kyro 385 CPU and an Adreno 630 GPU. The GPU promises a 30% improvement in graphics, as well as 30% better power efficiency, 2.5x faster display throughput and support for room-scale 6DOF and room mapping for VR and AR applications.

On the photography side, the chip offers a Spectra 280 ISP performs multiframe noise reduction on 16MP images at 60fps, with support for the Rec. 2020 colour gamut and 10-bit colour depth. As mentioned earlier, it also allows for 4K video capture with HDR at 60fps, as well as slo-mo 720p video at 480fps and 1080p video at 240fps.

According to the Ericsson Mobility Report 5G subscriptions will reach 1 billion by 2023, with 5G covering over 20% of the world population just 4 years after the first commercial 5G New Radio (NR) networks go live in 2019.

A number of perhaps predictable markets will get the first 5G deployments-- namely the US, S. Korea, Japan and China-- all based in dense urban areas. The forecast period also involves an 8X surge in mobile data traffic, reaching 110 Exabytes per month (or 5.5 million years of HD video streaming) per month.

The mention of streaming is relevant, since video is a main driver of mobile broadband traffic. Young millennials (in the 15-24 age bracket) stream 2.5X more than people over 45 years of age, and higher resolution and immersive 360-degree video will further impact data traffic consumption volumes.

ZTE claims the Axon M brings nothing less than "a new smartphone category"-- or in the least something rather interesting, since it features a foldable design with two full-size displays.

The Axon M has a pair of 5.2-inch 1920 x 1080 displays, one in the front and the other in the back. A hinge connects the two, allowing users to flip the rear display and slot it next to the front one, creating a single 6.75-inch display. Users can then either stretch apps across the larger display or take advantage of Android split-screen features to run two apps simultaneously, one on each screen. Users can even watch two different videos on the two screens, switching between audio streams as they want.

In addition, one can also "tent" the phone and mirror the displays, allowing two people to look at the same content from the front and back. ZTE promises the "top 100" Android apps work on the Axon M, with the tablet version of the app (if one exists, obviously) running when the it is in "extended" mode.
