Qualcomm has announced the Snapdragon X20 LTE modem, their 2nd-generation Gigabit LTE solution built on 10nm FinFET and offering what Qualcomm says are “a number of industry firsts”, which include first to Category 18 (downlink) and first to receive up to 12 spacial LTE data streams simultaneously.
“It is the first commercially announced Gigabit LTE chipset designed to deliver fiber-like LTE Category 18 download speeds of up to 1.2 Gbps, a 20 percent improvement in download speeds over the previous generation. Additionally, it allows support for up to 5x20 MHz downlink Carrier Aggregation (CA) across licensed and unlicensed FDD and TDD radio frequencies, as well as 4x4 MIMO on up to three aggregated LTE carriers. Lastly, it supports integrated Dual SIM Dual VoLTE (DSDV) capability, a first for Snapdragon LTE modems. These leading-edge features of the Snapdragon X20 LTE modem are supported by the first commercially announced single-chip RF transceiver capable of simultaneously receiving up to 12 spatial streams of LTE data.”
Compared the the X16 modem featured in the upcoming Snapdragon 835 SoC, the Snapdragon X20 LTE modem moves from Cat 16 to Cat 18 on the downlink, with support for 5x20 MHz (vs. the X16’s 4x20 MHz) Carrier Aggregation and “can simultaneously receive 12 unique streams of data on as few as three 20 MHz carriers”, with up to 256-QAM and 100 Mbps per stream. Uplink is at the same 2x20 MHz/64-QAM as the X16 modem, for speeds of up to 150 Mbps.
The X20 LTE modem now includes VoLTE for both cards in a dual-SIM implementation:
“The Snapdragon X20 LTE modem also features more advanced dual SIM functionality and, as the first Snapdragon LTE modem to support DSDV, it provides users with the benefits of Ultra HD Voice and other IMS-based services on both SIMs inserted into the device.”
Qualcomm has begun to sample the Snapdragon X20 LTE modem to customers, with the first commercial devices expected 1H 2018.
Full press release after the break.

We caught a glance at the new ASUS ZenBook 3 at CES and today Kitguru provides a full review of one, albeit a slightly different model. The UX3901UA model contains a Kaby Lake i5-7200U with HD 620 graphics, 8GB LPDDR3-2133 and a 512GB M.2 SATA SSD. The 12.5" screen is 1080p with no adaptive graphics or other tricks. Where things seem to go off the rails is when you look at the thickness of the Zenbook, at its thickest it is 11.9mm (0.46"). This means you get no ethernet nor USB type A plugs as they simply would not fit and you have to content yourself with a single Type C plug. For some the sacrifice is worth it; if you are one who likes petite sized computers you should head over for the full review.
"What has really caught my eye about the ZenBook 3 is its physical dimensions – it measures just 11.9mm thick, while it weighs a mere 910g. With Kaby Lake hardware inside, as well as the promise of a crisp 1080p display and Harman Kardon speakers, could this be our new ultrabook of choice?"

Living Long and Prospering
The open fork of AMD’s Mantle, the Vulkan API, was released exactly a year ago with, as we reported, a hard launch. This meant public, but not main-branch drivers for developers, a few public SDKs, a proof-of-concept patch for The Talos Principle, and, of course, the ratified specification. This sets up the API to find success right out of the gate, and we can now look back over the year since.
Thor's hammer, or a tempest in a teapot?
The elephant in the room is DOOM. This game has successfully integrated the API and it uses many of its more interesting features, like asynchronous compute. Because the API is designed in a sort-of “make a command, drop it on a list” paradigm, the driver is able to select commands based on priority and available resources. AMD’s products got a significant performance boost, relative to OpenGL, catapulting their Fury X GPU up to the enthusiast level that its theoretical performance suggested.
Mobile developers have been picking up the API, too. Google, who is known for banishing OpenCL from their Nexus line and challenging OpenGL ES with their Android Extension Pack (later integrated into OpenGL ES with version 3.2), has strongly backed Vulkan. The API was integrated as a core feature of Android 7.0.
On the engine and middleware side of things, Vulkan is currently “ready for shipping games” as of Unreal Engine 4.14. It is also included in Unity 5.6 Beta, which is expected for full release in March. Frameworks for emulators are also integrating Vulkan, often just to say they did, but sometimes to emulate the quirks of these system’s offbeat graphics co-processors. Many other engines, from Source 2 to Torque 3D, have also announced or added Vulkan support.
Finally, for the API itself, The Khronos Group announced (pg 22 from SIGGRAPH 2016) areas that they are actively working on. The top feature is “better” multi-GPU support. While Vulkan, like OpenCL, allows developers to enumerate all graphics devices and target them, individually, with work, it doesn’t have certain mechanisms, like being able to directly ingest output from one GPU into another. They haven’t announced a timeline for this.
As I mentioned last week, my ZTE Axon 7 has just received Android 7.0 Nougat, which also unlocked Google Daydream VR. I wasn’t able to pick up Google’s VR headset at the time, but now I can, so I did, and I spent a couple of hours messing around with it.
First, I have to say I am very glad that Google made one headset (and controller) that works with all Daydream-compatible phones. That wasn’t entirely clear when I ordered my Axon 7 last summer, and I feared it would lead to a lot of waiting for my OEM to release a specific headset that may or may not be as good as any another vendor’s, especially sight unseen. I don’t really know how they properly align the screens, across all possible phones and accounting for user-error, but it seems to accept my phone perfectly without really any fiddling. Maybe it’s a simpler problem than I am envisioning, but, either way, the one viewer works with my ZTE Axon 7 -- it’s not just for the Pixel.
My second point is that the phone gets very hot, very quick. I’m sure ZTE knows about this, and the phone is designed around it, but it doesn’t just get warm, it borders on hot-to-the-touch at times. To be safe, I’m removing the case each time I insert it into the Daydream View, although the device seems to work either way. The battery does drain quickly, relative to other workloads, but a single, hour-or-so VR sitting took about 25% off (~75% remaining). Despite the heat and the quick battery drain, you will probably be done with a VR sitting before the device is, so I consider those aspects to be all-around positive.
As for the YouTube app, I’m glad that the virtual screen for standard video can be adjusted in pretty much any way. You can make it bigger or smaller with the track pad, pull it in any direction with motion controls, and adjust whether it’s flat or curved (so all points are equidistant) in the settings. If you want to lay on your back in bed and watch movies “on the ceiling”, then you can... and without holding the phone over your face while your arms go numb.
Yes, I’m speaking from experience.
As for games? Eh... about the only thing that caught my eye is maybe “Keep Talking and Nobody Explodes”. I’m pleasantly surprised it’s there, but it’s about the only thing that is. I knew there wasn’t a whole lot of apps, and that’s fine for me, but you probably shouldn’t get too excited outside of video.
Also, it’d be nice to see Google Chrome in VR. Get on that, Google! A virtual void would make a good place to keep my many, many tabs. It will apparently support WebVR content very soon, but in a “browse, click the Daydream button, mount it in the View, and put it on your head, then undo all that when you’re done” sort of way. It’d be nice to just... stay in the headset to browse.
Anywho, I have it, and those are my thoughts. It’s early, but it seems to work pretty well. I haven’t tried an Oculus Rift or an HTC Vive yet, though, so I can’t make any comparisons there.
Introduction and Specifications
The Mate 9 is the current version of Huawei’s signature 6-inch smartphone, building on last year’s iteration with the company’s new Kirin 960 SoC (featuring ARM's next-generation Bifrost GPU architecture), improved industrial design, and exclusive Leica-branded dual camera system.
In the ultra-competitive smartphone world there is little room at the top, and most companies are simply looking for a share of the market. Apple and Samsung have occupied the top two spots for some time, with HTC, LG, Motorola, and others, far behind. But the new #3 emerged not from the usual suspects, but from a name many of us in the USA had not heard of until recently; and it is the manufacturer of the Mate 9. And comparing this new handset to the preceding Mate 8 (which we looked at this past August), it is a significant improvement in most respects.
With this phone Huawei has really come into their own with their signature phone design, and 2016 was a very good product year with the company’s smartphone offerings. The P9 handset launched early in 2016, offering not only solid specs and impressive industrial design, but a unique camera that was far more than a gimmick. Huawei’s partnership with Leica has resulted in a dual-camera system that operates differently than systems found on phones such as the iPhone 7 Plus, and the results are very impressive. The Mate 9 is an extension of that P9 design, adapted for their larger Mate smartphone series.
Intro, Exterior and Internal Features
Lenovo sent over an OLED-equipped ThinkPad X1 Yoga a while back. I was mid-development on our client SSD test suite and had some upcoming travel. Given that the new suite’s result number crunching spreadsheet ends extends out to column FHY (4289 for those counting), I really needed a higher res screen and improved computer horsepower in a mobile package. I commandeered the X1 Yoga OLED for the trip and to say it grew on me quickly is an understatement. While I do tend to reserve my heavier duty computing tasks and crazy spreadsheets for desktop machines and 40” 4K displays, the compute power of the X1 Yoga proved itself quite reasonable for a mobile platform. Sure there is a built in pen that comes in handy when employing the Yoga’s flip over convertibility into tablet mode, but the real beauty of this particular laptop comes with its optional 2560x1440 14” OLED display.
OLED is just one of those things you need to see in person to truly appreciate. Photos of these screens just can’t capture the perfect blacks and vivid colors. In productivity use, something about either the pixel pattern or the amazing contrast made me feel like the effective resolution of the panel was higher than its rating. It really is a shame that you are likely reading this article on an LCD, because the OLED panel on this particular model of Lenovo laptop really is the superstar. I’ll dive more into the display later on, but for now let’s cover the basics:

Well that was quick. About two weeks ago, we reported on ZTE Mobile Deutschland’s Facebook post that said Android 7.0 would miss January, but arrive some time in Q1. For North America, that apparently means the second week of February, because my device was just notified, about an hour ago, that A2017UV1.1.0B15 was available for over-the-air update. It just finished installing.
In my case, I needed to hold the on button a few times to get the phone to boot into the second stage of installation, but ZTE mentions it in the pre-install notes, so that’s good. Then, when the phone moved on to the new lock screen, my fingerprint reader didn’t work until after I typed in the lock screen password. I’m not sure why the phone didn’t accept the fingerprint reader until after I successfully logged in, especially since it used the fingerprints on file from Android 6.0, I didn’t need to set it up again, but it’s a small inconvenience. Just don’t perform the update if you can’t access your password manager and you don’t remember the unlock code off the top of your head.
While I don’t have a Daydream VR headset, I’ll probably pick one up soon and give it a test. The Daydream app is installed on the device, though, so you can finally enjoy Android-based VR content if you pick one up.
If your phone hasn’t alerted you yet, find your unlock password and check for updates in the settings app.

In conjunction with Ericsson, Netgear, and Telstra, Qualcomm officially unveiled the first Gigabit LTE ready network. Sydney, Australia is the first city to have this new cellular spec deployed through Telstra. Gigabit LTE, dubbed 4GX by Telstra, offers up to 1Gbps download speeds and 150 Mbps upload speeds with a supported device. Gigabit LTE implementation took partnership between all four companies to become a reality with Ericsson providing the backend hardware and software infrastructure and upgrades, Qualcomm designing its next-gen Snapdragon 835 SoC and Snapdragon X16 modem for Gigabit LTE support, Netgear developing the Nighthawk M1 Mobile router which leverages the Snapdragon 835, and Telstra bringing it all together on its Australian-based cellular network. Qualcomm, Ericsson, and Telstra all see the 4GX implementation as a solid step forward in the path to 5G with 4GX acting as the foundation layer for next-gen 5G networks and providing a fallback, much the same as 3G acted as a fallback for the current 4G LTE cellular networks.
Gigabit LTE Explained

What exactly is meant by Gigabit LTE (or 4GX as Telstra has dubbed the new cellular technology)? Gigabit LTE increases both the download and upload speeds of current generation 4G LTE to 1Gbps download and 150 Mbps upload speeds by leveraging several technologies for optimizing the signal transmission between the consumer device and the cellular network itself. Qualcomm designed the Snapdragon X16 modem to operate on dual 60MHz signals with 4x4 MIMO support or dual 80MHz signals without 4x4 MIMO. Further, they increased the modem's QAM support to 256 (8-bit) instead of the current 64 QAM support (6-bit), enabling 33% more data per stream - an increase of 75 Mbps to 100 Mbps per stream. The X16 modem leverages a total of 10 communication streams for delivery of up to 1 Gbps performance and also offers access to previously inaccessible frequency bands using LAA (License Assisted Access) to leverage increased power and speed needs for Gigabit LTE support.
The German offices of ZTE Mobile have announced (via their Facebook page) that the Android 7.0 update will be coming later in this quarter, which would be before the end of March. In November, this branch announced that the update would be coming in January. This update is supposed to bring Daydream to the handset, as this was one of the big promises that ZTE made about the device before it launched. They are not confident with it in its current state, though.
Our readers were asking about my opinion of the device, since I published a “Just Delivered” post about it four months ago. I said that I would wait until the Nougat release, which I was, at the time, expecting in October or November, because I had a feeling that ZTE envisioned the phone with that OS version. Since then, bugs have come and gone, most of which were relatively benign, like messing up whitespace in the lock screen’s current date. Personally, I started getting a bug where my camera would occasionally fail to focus, instead humming and blurring like it’s focusing in and out tens or hundreds of times per second until you close the app using the camera. (It started happening, off and on, just after the last service update, although it could just be a coincidental hardware issue with my unit. I’m waiting until I see it in Nougat to call customer support.)
Either way, it’s probably a good thing that ZTE is taking their time with this one. I’m guessing this update is when those who adopted the Axon 7 will begin to solidify judgments about the company as a higher-end phone vendor going forward.
