Introduction and CPU Performance
We had a chance this week to go hands-on with the Snapdragon 820, the latest flagship SoC from Qualcomm, in a hardware session featuring prototype handsets powered by this new silicon. How did it perform? Read on to find out!
As you would expect from an all-new flagship part, the Snapdragon 820 offers improvements in virtually every category compared to their previous products. And with the 820 Qualcomm is emphasizing not only performance, but lower power consumption with claims of anywhere from 20% to 10x better efficiency across the components that make up this new SoC. And part of these power savings will undoubtedly come as the result of Qualcomm’s decision to move to a quad-core design with the 820, rather than the 8-core design of the 810.
So what exactly does comprise a high-end SoC like the Snapdragon 820? Ryan covered the launch in detail back in November (and we introduced aspects of the new SoC in a series of articles leading up to the launch). In brief, the Snapdragon 820 includes a custom quad-core CPU (Kryo), the Andreno 530 GPU, a new DSP (Hexagon 680), new ISP (Spectra), and a new LTE modem (X12). The previous flagship Snapdragon 810 used stock ARM cores (Cortex-A57, Cortex-A53) in a big.LITTLE configuration, but for various reasons Qualcomm has chosen not to introduce another 8-core SoC with this new product.
The four Kryo CPU cores found in the Snapdragon 820 can operate at speeds of up to 2.2 GHz, and since is half the number of the octo-core Snapdragon 810, the IPC (instructions per clock) of this new part will help determine how competitive the SD820's performance will be; but there’s a lot more to the story. This SoC design placed equal emphasis on all components therein, and the strategy with the SD820 seems to be leveraging the capability of the advanced signal processing (Hexagon 680) which should help offload the work to allow the CPU to work with greater efficiency, and at lower power.

Coming just a day after Qualcomm officially launched their Snapdragon 820 SoC, Samsung is today unveiling their latest flagship mobile part, the Exynos 8 Octa 8890.
The Exynos 8 Octa 8890 is built on Samsung’s 14 nm FinFET process like the previous Exynos 7 Octa 7420, and again is based on the a big.LITTLE configuration; though the big processing cores are a custom design this time around. The Exynos 7420 was comprised of four ARM Cortex A57 cores and four small Cortex A53 cores, and while the small cores in the 8890 are again ARM Cortex A53, the big cores feature Samsung’s “first custom designed CPU based on 64-bit ARMv8 architecture”.
“With Samsung’s own SCI (Samsung Coherent Interconnect) technology, which provides cache-coherency between big and small cores, the Exynos 8 Octa fully utilizes benefits of big.LITTLE structure for efficient usage of the eight cores. Additionally, Exynos 8 Octa is built on highly praised 14nm FinFET process. These all efforts for Exynos 8 Octa provide 30% more superb performance and 10% more power efficiency.”
Another big advancement for the Exynos 8 Octa is the integrated modem, which provides Category 12/13 LTE with download speeds (with carrier aggregation) of up to 600 Mbps, and uploads up to 150 Mbps. This might sound familiar, as it mirrors the LTE Release 12 specs of the new modem in the Snapdragon 820.
Video processing is handled by the Mali-T880 GPU, moving up from the Mali-T760 found in the Exynos 7 Octa. The T880 is “the highest performance and the most energy-efficient mobile GPU in the Mali family”, with up to 1.8x the performance of the T760 while being 40% more energy-efficient.
Samsung will be taking this new SoC into mass production later this year, and the chip is expected to be featured in the company’s upcoming flagship Galaxy phone.
Full PR after the break.

You can see in the video that The Register linked to that this particular vulnerability is neither quick nor elegant but it is most certainly effective. By entering an extremely long string of digits into the password field, accomplished with multiple copies and pastes, while the camera app is active you can cause the lock screen application to crash on all but the newest version of Android 5. Unfortunately the effect of that crash is to drop you onto the phones home screen, thus allowing complete access to the phone. If you are running a version of Android 5 you should consider switching to a PIN or pattern unlock, at least for the time being.
"If you've got an Android 5 smartphone with anything but the very latest version of Lollipop on it, it's best to use a PIN or pattern to secure your lock-screen – because there's a trivial bypass for its password protection."

The new Ubuntu powered Aquaris E4.5 and the Aquaris E5 HD are now available but thanks to North America's carriers not supporting HPSA+ properly, or in many cases at all, the best you could hope for on this side of the pond is a 2G connection. They chips inside the phones are quad-core ARM Cortex A7's running at 1.3GHz with Mali 400 graphics. The E5 has a 5" screen with a resolutions of 720 x 1280, the 4.5 is 4.5" in size with a 540 x 960 resolution. Overall the specs are not awe inspiring and the prices of roughly $190 and $220 seem a bit high but are certainly lower than what you would pay for a new Samsung or Apple product without a contract. If you are interested then follow the links from The Register to order one.
"In a Tuesday blog post, Ubuntu maker Canonical said that BQ, its Spanish hardware partner, has opened a new online store where customers around the world can order the Aquaris E4.5 and the Aquaris E5 HD, the two current Ubuntu models."

Marshall has managed to do something almost no other company has been able to recently, kept a brand new product completely secret. They have just released a brand new Android smartphone with an internal soundcard which allows you to play lossless FLAC audio files, something not common amongst the smartphones on the market. The branding is immediately obvious and there are some unique additions such as the use of brass on the two headphone jacks and a volume wheel as opposed to a rocker switch. The hardware is not terribly impressive, a 720p 4.7" display powered by a Snapdragon 410 with 2 GB of RAM and 16 GB of local storage. This phone is more about the audio, how high a resolution do you want for your equalizer anyways? Check out more at The Register.

9to5google is reporting specs of the upcoming Moto G refresh, and it looks like the phone will carry over the internals of the current Moto E with a Snapdragon 410 SoC, and add an improved 13MP camera.
The current Moto G has been a favorite for many as a low-cost unlocked option (and one that runs mostly stock Android), and the adoption of the faster SoC with integrated (Cat 4) LTE baseband is a necessary move to update a device that in its current iteration is limited to 3G data speeds. It is interesting that the SoC would only match that of the $149 2015 Moto E (reviewed here), but it makes sense from a financial standpoint if the rumored Moto G is to be sold at or below its current $179 price point.
There is certainly stiff competition in the midrange smartphone market, bolstered considerably by the recently released ASUS Zenfone 2 (reviewed here as well) which starts at $199 unlocked; and with devices like the new Zenfone offering full 1080p screens the rumored choice of the Moto G’s existing 5-inch 720p screen returning in 2015 might be another indication that this new phone will feature a very aggressive price.

The phone is also rumored to ship with Android 5.1.1, which would carry on the recent tradition of Motorola phones running the latest versions of Android. All of this is unconfirmed information based on leaks or course, but regardless of its final form more options are always welcome in the $200-and-under unlocked phone space - and this year is shaping up to be a good one for consumers.

The new Sony Xperia Z3+ is a tiny bit thinner than the non-plus model at 146x72x6.9mm and 144g compared to 146x72x7.3mm and 152g. The display is unchanged, a 5.2" IPS screen with a 1080x1920 resolution but the processor received a significant upgrade, it is now a 64-bit octa-core Qualcomm Snapdragon 810. The phone ships with Android 5.0 and The Inquirer got a chance to try it out. The new processor handles 4K video perfectly and the phone feels snappier overall compared to the previous model, check out their full experience here.

Introduction and Specifications
The ASUS Zenfone 2 is a 5.5-inch smartphone with a premium look and the specs to match. But the real story here is that it sells for just $199 or $299 unlocked, making it a tempting alternative to contract phones without the concessions often made with budget devices; at least on paper. Let's take a closer look to see how the new Zenfone 2 stacks up! (Note: a second sample unit was provided by Gearbest.com.)
When I first heard about the Zenfone 2 from ASUS I was eager to check it out given its mix of solid specs, nice appearance, and a startlingly low price. ASUS has created something that has the potential to transcend the disruptive nature of a phone like the Moto E, itself a $149 alternative to contract phones that we reviewed recently. With its premium specs to go along with very low unlocked pricing, the Zenfone 2 could be more than just a bargain device, and if it performs well it could make some serious waves in the smartphone industry.
The Zenfone 2 also features a 5.5-inch IPS LCD screen with 1920x1080 resolution (in line with an iPhone 6 Plus or the OnePlus One), and beyond the internal hardware ASUS has created a phone that looks every bit the part of a premium device that one would expect to cost hundreds more. In fact, without spoiling anything up front, I will say that the context of price won't be necessary to judge the merit of the Zenfone 2; it stands on its own as a smartphone, and not simply a budget phone.
The big question is going to be how the Zenfone 2 compares to existing phones, and with its quad-core Intel Atom SoC this is something of an unknown. Intel has been making a push to enter the U.S. smartphone market (with earlier products more widely available in Europe) and the Zenfone 2 marks an important milestone for both Intel and ASUS in this regard. The Z3580 SoC powering my review unit certainly sounds fast on paper with its 4 cores clocked up to 2.33 GHz, and no less than 4 GB of RAM on board (and a solid 64 GB onboard storage as well).

Tagged: wearable, tech world, smartwatch, smartphone, smart cast, magic view, lenovo tech world, Lenovo, concept
Today at the Lenovo Tech World keynote presentation, Lenovo CTO Peter Hortensius took the opportunity to show some of the far reaching concepts for smartphones and smartwatches.
The Magic View smartwatch is a stylish, round smartwatch reminiscent of the Moto 360 that seems from the concept renderings to be based around Android Wear. However, the uniqueness comes from what Lenovo is claiming makes it the only smartwatch with two screens.
Optical reflection is used inside of a portion of the strap in order to project a second “virtual interactive display” more than 20 times larger than the integrated display. This is made possible through Lenovo-designed silicon aimed at miniaturizing the components for this type of projection while maintaining the same performance.
Lenovo claims this secondary screen will be useful for things like maps, as well as photo and video viewing, but it be remains to be seen if users would favor a virtual display like this over simply using their existing smartphone display. Privacy is also a big part of what Lenovo is pitching with the Magic View. Since users must place the lens portion next to their eye, other people in the same area cannot look over their shoulders and view potientially sensitive information.
The Lenovo Smart Cast concept plays on a similar idea as the Magic View. Through the use of a build in laser projector, as well as specialized sensors, Lenovo aims at allowing users to project a large virtual touch screen onto tabletop surfaces.
With the use of infrared sensors, users can touch the surface underneath the projection and interact just as if it were a physical display. Lenovo points towards this being useful for such applications as virtual keyboards in productivity apps, or even for media control of projected movies and light gaming such as Fruit Ninja.
The projected display is also independent of the smartphone display, allowing things such as two separate views for video chatting applications.
It remains to be seen if these concepts will ever actually make it into production devices, and if those devices will ever hit North America, but it's always interesting to see what R&D divisions of large companies like Lenovo are up to.
