Your Android may suffer a Meltdown

Researchers in Austria have found a way to utilize Meltdown to hack Galaxy S7 smartphones, a bad sign for security.  It was previously discovered that ARM's Cortex A75 was susceptible to the vulnerability but this is the first time we have seen this exploit successfully used on a Snapdragon 820 or Exynos 8890 chipset.  Even better is that these researchers have discovered variants which can affect older chipsets, meaning that far more phones may be vulnerable than we ever imagined.  You can take a peek over at The Inquirer, if you are looking to ruin your day.

Samsung Announces Galaxy S7 Active

The Samsung Galaxy S7 launched a couple of months ago. While it wasn't too bad from a durability standpoint, I have heard people complain that their screen fractured from a seemingly low-risk fall. Over time, it seemed like they were somewhat fluke examples because it kind-of fell off the radar. Still, if you want the specifications of a Galaxy S7, and you want to extra reliability without placing it inside a case, Samsung has added a version of the phone in their Active line.

AT&T doesn't list pricing and they only state “coming soon” for availability. They do mention that the battery will get a significant bump in capacity, though. The original Galaxy S7 and Galaxy S7 Edge phones have a 3,000 mAh and a 3,700 mAh battery, respectively, but the Galaxy S7 Active is larger: 4,000 mAh. Critics like the battery life of the original S7, many claiming that it lasts a whole, heavy-use day for them, but an extra 33% is nothing to sneer at.

If only it comes to Canada, too...

Hardware Experience

Seeing Ryan transition from being a long-time Android user over to iOS late last year has had me thinking. While I've had hands on with flagship phones from many manufacturers since then, I haven't actually carried an Android device with me since the Nexus S (eventually, with the 4.0 Ice Cream Sandwich upgrade). Maybe it was time to go back in order to gain a more informed perspective of the mobile device market as it stands today.

So that's exactly what I did. When we received our Samsung Galaxy S7 review unit (full review coming soon, I promise!), I decided to go ahead and put a real effort forth into using Android for an extended period of time.

Full disclosure, I am still carrying my iPhone with me since we received a T-Mobile locked unit, and my personal number is on Verizon. However, I have been using the S7 for everything but phone calls, and the occasional text message to people who only has my iPhone number.

Now one of the questions you might be asking yourself right now is why did I choose the Galaxy S7 of all devices to make this transition with. Most Android aficionados would probably insist that I chose a Nexus device to get the best experience and one that Google intends to provide when developing Android. While these people aren't wrong, I decided that I wanted to go with a more popular device as opposed to the more niche Nexus line.

Whether you Samsung's approach or not, the fact is that they sell more Android devices than anyone else and the Galaxy S7 will be their flagship offering for the next year or so.

MWC 16: Epic Games Unveils ProtoStar Demo on Galaxy S7

Mobile World Congress starts with a big bang... ... ... :3

Okay, not really; it starts with the formation of a star, which happens on a continual basis across the universe. I won't let facts get in the way of a pun, though.

As for the demo, it is powered by Unreal Engine 4 and runs on a Samsung Galaxy S7 with the Vulkan API. The setting seems to be some sort of futuristic laboratory that combines objects until it builds up into a star. It is bright and vibrant, with many particles, full-scene anti-aliasing, reflections, and other visual effects. The exact resolution when running on the phone was never stated, but the YouTube video was running at 1080p30, and the on-stage demo looked fairly high resolution, too.

Epic Games lists the features they added to mobile builds of Unreal Engine 4 for this demo:

  • Dynamic planar reflections
  • “Full” GPU particle support, which includes vector fields.
  • Temporal Anti-Alising, which blends neighboring frames to smooth jaggies in motion.
  • ASTC texture compression (created by ARM and AMD for OpenGL and OpenGL ES)
  • Full scene dynamic cascaded shadows
  • Chromatic aberration
  • Dynamic light refraction
  • Filmic tonemapping curve, which scales frames rendered in HDR to a presentable light range
  • Improved static reflections
  • High-quality depth of field
  • Vulkan API for thousands of onscreen, independent objects.

The company has not stated which version of Unreal Engine 4 will receive these updates. I doubt that it will land in 4.11, which is planned for March, but they tend to release a full dot-version every one to three months. They also have early previews for those who wish to try it early, some compiled leading up to launch, and others that need to be built from GitHub.
