I got to spend some time with the brand new Samsung Galaxy S7 and S7 Edge phones at MWC this week in Barcelona. Is this your next Android flagship phone?

MWC 16: Qualcomm talks antenna improvements in Galaxy S7

No one is more excited to see the Snapdragon 820 processor in the Galaxy S7 (in some regions) than Qualcomm and Qualcomm's investors. Missing the S6 design win completely was a big blow to the SD 810 but the move to FinFET technology and a new SoC design have put the SD 820 back in the driver's seat for flagship smartphones it seems. While talking with Qualcomm's Peter Carson, Senior Director of Marketing and Modems, I learned quite a bit about the X12 LTE modem integration with the Galaxy S7 as well. As it turns out, the application processor itself isn't the only thing that has impressed OEMs or that will benefit consumers. 

Modem marketers have a problem - quantifying the advantages of one LTE modem over another can be troublesome and complex. It's not as simple as X% faster or X% longer battery life, though those aspects of performance see improvement with better modem technology. And while of course the new announcement of Gigabit LTE is getting all the media attention at Mobile World Congress this week, there is a lot of excitement internally about the shipping implementation of the S7's modem.

The Galaxy S7 encompasses the most advanced Qualcomm TruSignal antenna technology implementation to date, combining several features to add real-world benefits to the cellular performance of the device.

First, the S7 will feature the most advanced version of the antenna tuner including a closed loop feedback cycle that will tweak antenna properties in real time based on sensor data and current signal properties. If the proximity sensor is activated or you are rotating or moving the mobile device, the receiver can adjust antenna properties to improve signal reliability measurably.

The best examples fall on the cell edge, where dropped calls are common and low voice quality are found. You can improve the gain of the antenna, that is adversly affected by simply holding the device, for much better reliability and even data throughput. That means fewer dropped calls and network drops for users that have moderate service reliability. Voice quality will get better as well, as the error rates that cause data loss in low signal areas will be reduced. 

But even users that have a good signal can get benefits from the tech - gains of just 2-3 db will allow the modem and receiver to go into a lower power state, reducing 20% of the modem power draw. That won't equate to 20% total system battery life improvement but users that depend on their phones for extended use will see benefits from this integration.

Another TruSignal feature included in this modem implementation is smart transmit antenna switching. The simple explanation here is that the modem can swap which antennas are in receive and transmit modes in order to improve the transmit (upload) performance by as much as 10db! Based on properties of the antenna signal, position of the device and if you are in a heavy upload workload (posting some photos to Facebook, a video to YouTube), TruSignal allows the modem to change in real-time.

These techniques are additive so Galaxy S7 owners will find that both the antenna tuner and antenna switching are going to move the cellular performance forward, though Qualcomm isn't saying if ALL implementation of Samsung's new flagship smartphone will implement the features. I would guess that we'll see this on the Snapdragon 820 + X12 powered models only, but I haven't learned yet which modem the Exynos-powered versions are using yet. Turns out the versions of the S7 that utilize the Samsung Exynos SoC are using a non-Qualcomm modem, so they will not support the features seen here.

Rumor About Samsung's Upcoming Flagship Phone

The follow-up to the Samsung Galaxy S6 is already being rumored, which people are obviously calling the Galaxy S7. The last two phones were unveiled at Mobile World Congress in Barcelona, Spain, which takes place in late February / early March. Information coming out in November is a bit... early. Some sites believe that Samsung will announce the phone in January, but who knows? Some of the rumors are interesting, though.

The one that catches my attention is the potential inclusion of a microSD card slot. External storage is rare these days, with Google removing it from their Nexus line and severely limiting what apps can do with the contents. That said, Android 6.0, recently released for a few devices, made further changes to increase its capabilities. You can now use SD cards as internal storage, but only if you agree to format and encrypt the storage to use only on that device. While the recent batch of Nexus phones don't include a microSD card slot, the changes might be enough to sway third-party manufacturers to include a slot.

As a developer, it would certainly be nice, especially if you intend to develop software that uses an SD card. Makes sense, right? Purchasing a developer phone that has all the features you might want to target?

Speaking of developer phones, the upcoming device should have a top-of-the-line processor in it. Reports are split between the Snapdragon 820 and the Exynos 8890. If it's the latter, availability is expected Q1 2016; the former started sampling a few months ago and was launched on November 11th. As such, SoC availability should be ready if Samsung intends to launch the phone early, regardless of the chosen chip, but that's probably not the limiting factor. It is also entirely possible that Samsung could include different processors for different markets. Qualcomm was absent from the Galaxy S6 line, but the S5 had some sub-models using Qualcomm processors and others Samsung's own implementation.

Either way, they are fast processors that support OpenGL ES 3.1 + AEP at the very least. The Adreno 530 is rated for about 550 GFLOPs, which is a tiny bit faster than a GeForce 9800 GT, although with Vulkan-level feature support (provided correct drivers). Thankfully Google has been more friendly to Khronos-based standards, and Samsung even more so.

When will we know for sure? Don't know. How much will it cost? Don't know. What will it be officially called? Don't know, but anything other than Galaxy S7 would be surprising. Would it make sense for Samsung to shake up the date and other long-running details? Well, the Galaxy S6 launch was lackluster, so this would be the most likely time for them to be squirrely. We'll see.

Computex: Acer announces Aspire S7 touchscreen 11-in and 13.3-in Ultrabooks

In what will likely be the first of dozens of such exposes this week, Acer has just announced a pair of Ultrabooks that will fall under the new Aspire S7 brand in both 11-in and 13.3-in screen sizes.  According to a post at Engadget, the new Ultrabooks are actually touch enabled and will support being laid completely flat with a 180 degree hinge.

While other details on the specifications seem to be missing from the Computex announcement, we can assume these are going to be Intel Ivy Bridge based designs.  The screens are being called "full HD" which indicates a 1080p resolution that would really help the S7 stand out from other current Ultrabooks (as well as raise the price). 

Battery life is claimed at 9 hours on the 11-in model and 12 hours on the 13.3-in model, though all such claims should be tested before you plop down cash on a preorder.

Can someone please explain how laying down a notebook flat is helpful?

The Ultrabook is less than 13mm thick and the chassis is built with a unibody aluminum design which should immediately draw comparisons to the Apple Macbook Pro.  A backlit keyboard and a glass lid on the 13-in model round out our known information on the Aspire S7 but don't expect availability until we see Windows 8 ship sometime this fall.
