‘3D’ white graphene could revolutionize gadget cooling
Graphene seems to be the new millennium’s wonder material: it can be used to build more powerful processors, more efficient solar cells, better sounding headphones and, apparently, can even be deep-fried to create long-lasting batteries. Now, researchers at Rice University think that a “3D” variant of the material could change the way we cool our gadgets.
Normal graphene is already a pretty good heat conductor, but it has limitations–heat moves easily across the surface of stacked graphene, but not so well across the material’s multiple layers. That problem, however, can be solved: according to simulations at Rice, creating 3D structures of white graphene with boron nitrade nanotubes can overcome these thermal limitations, allowing for unimpeded heat transfer in all directions.
In laymen’s terms, that all means that this research could eventually lead to new, smaller, more efficient thermal solutions–making it possible for us to cool smaller and more powerful electronics in the future. Sounds good to me.

The OnePlus 2 13MP f/2.0 Camera gets reviewed
Popular YouTuber Marques Brownlee was lucky enough to get his hands on an early release of the long-awaited OnePlus 2 and he’s taken to what he does best to give the camera on the device an early review before it’s even released.
Only pictures were released that were shot by the camera but they show a 13 Megapixel camera with a f/2.0 lens and are of a decent quality.
There is an automatic mode and also a clear shot, HDR, and beauty mode on the software behind the OnePlus 2 camera and the video mode also shoots in 4K.
The pictures look almost as good as the Galaxy S6 but not quite on par, which is down to the f/2.0 of the OnePlus 2, but certainly proves that the camera on the upcoming device will be up there with the best Android shooters on the market.
The post The OnePlus 2 13MP f/2.0 Camera gets reviewed appeared first on AndroidGuys.
HTC says the One M9 is already powered by the Snapdragon 810 v2.1
Qualcomm’s Snapdragon 810 is one of the most controversial processors of all time, largely thanks to a report back in March that claimed the HTC One M9 heated up to dangerous levels because of the processor’s overheating issues. Ever since that report, the processor (and the phone) have been scrutinized heavily by the tech community, thus giving both a bad name overtime.

Since then, a few manufacturers have released handsets that are powered by the supposedly cooler Snapdragon 810 v2.1 chipset, or at least that’s how the companies are marketing it. Interestingly enough, the HTC One M9 might already be powered by this newer, cooler version, according to HTC’s Senior Global Online Communications Manager, Jeff Gordon.
Gordon noted earlier today that according to information he’s received from Qualcomm “virtually all” OEMs that have announced handsets running the Snapdragon 810 are already using the v2.1 processor. Moreover, he explains to one user that the HTC One M9 is in fact powered by the newer version as well. Take a look:
The truth, according to what Qualcomm tells me, is virtually all OEMs who’ve announced devices with Snapdragon 810 are currently using v2.1.
— Jeff Gordon (@urbanstrata) July 15, 2015
A handful of devices have already been marketed as running the Snapdragon 810 v2.1, including the upcoming OnePlus 2.

The HTC One M9 has perhaps been the biggest offender of heat-related problems among spectators, though we never really experienced too many problems with the handset in our full review. With that said, thanks to its bad reputation, it’s no secret that many folks are nervous to adopt the handset due to potential overheating issues.
If the information from Gordon proves true, it looks like most Snapdragon 810 devices already use the newest version of Qualcomm’s flagship processor. With that said, you probably don’t have anything to worry about when it comes to overheating issues, but that all depends on which handset you’re using. The One M9 has received multiple software updates that aim to fix heat management issues, while on the other hand, Sony’s Xperia Z3+ has actually proven itself to be quite toasty most of the time.
Diving into Android M: Visual voicemail makes its way to the dialer app
We’re well on our way into checking out all of the goodies the second Android M developer preview brings to the table, and so far quite a few notable features are present in the update. Google has (re)revamped the app drawer, given us the ability to edit what shows up in the status bar, and much more.
You can find all of the changes present in both Android M previews by following the link below, which I definitely recommend you do if you’re interested in checking out what may or may not make it into the next version of Android. Also, if you happen to own a Nexus 5, 6 or 9, you can download the newest dev preview by heading to this link.

The Preview 2 build of Android M introduces a handy little feature that will probably make most of our lives much easier. You see, smartphones are great at doing a lot of things, but they’re also really bad at doing some things. As it stands now, listening to a voicemail on your Android device can be quite annoying. You need to call your voicemail, listen to the prompts, listen to the voicemail message, most likely delete it, then go about your day. The second Android M dev preview aims to make this process easier through the dialer application.
Visual voicemail, a handy feature that’s been available through Google Voice and third party apps for some time, now has its own tab in the new preview. The tab is located on the right side of the dialer app. You’ll be able to see a list of your voicemails, each separated by individual cards. Expanding each card will give you play, pause, volume and trash icons, as well as shortcuts that can be used for texting or calling that person back right away.
Right now, Google has only added support for this feature for Orange in France. Folks on T-Mobile will be able to use the feature when the final preview is released, though some users are already reporting that it’s working for them.
Keep in mind that just about everything listed in this post may change by the time Android M is actually released to the general public. If you’re running the second M preview, how is it working for you? Have you tested out the visual voicemail feature yet? If so, be sure to let us know about your experiences in the comment section below!
Apple Releases EFI Firmware Update 1.8 for Late-2012 Mac Mini
Apple today released a new firmware update for late-2012 Mac mini models to fix a problem that could prevent a USB keyboard from being recognized after the Mac wakes from sleep.
This update is recommended for Mac mini (late 2012) models. This update addresses an issue that may prevent a USB keyboard from being recognized after the system wakes from sleep.
Apple recommends all late-2012 Mac mini owners download the firmware update, which measures in at 4.8MB. It’s available through the Software Update mechanism in the Mac App Store or directly through Apple’s support website.
Today’s update is the first firmware update the 2012 Mac mini has received since December of 2012, when Apple released an update to address an HDMI video flickering issue.
The 2012 Mac mini is a previous-generation model that Apple replaced with the current Mac mini in 2014.
