If you don’t mind using your whole hand, you can swipe from the right side to left to capture a shot. You should be slow and deliberate in your gesture, however.  

You can also use two buttons in tandem, which you may find faster and more accurate. But your fingers will need to press simultaneously. 

1. Place one finger on the power button, which is located on the right side. Don’t press it yet.

2. Cover the home button with another finger.

3. Hit both buttons simultaneously. If you hit one or the other first, you’ll end up going to home or putting the  phone to sleep, rather than taking a screenshot.

After you have taken a screenshot, you can find it a number of ways:

If you have automatic photo backup turned on in Facebook, Dropbox, Google+ or any other application, your screenshots will get uploaded just like pictures you snap with your camera. If you have Dropbox on  your PC and phone, the images will be available on your computer just a few seconds after you snap them on the Galaxy S6.

How-Old.net started as an experiment with Microsoft’s newly released face detection APIs. Corom Thompson and Santosh Balasubramanian, Engineers in Information Management and Machine Learning at Microsoft, explained in a blog post that they expected 50 users for this test but have seen tens of thousands of people flock to the site during this week's Microsoft Build Developer Conference.

“We were shocked. Within a few hours, over 35,000 users had hit the page from all over the world (about 29k of them from Turkey, as it turned out -- apparently there were a bunch of tweets from Turkey mentioning this page),” they wrote. “What a great example of people having fun thanks to the power  of [machine learning].”

Machine Learning Apps Made Easy

What may be more interesting is that it only took a couple of developers one day to create How-Old.net and it’s fairly accurate. The developers created a pipeline from the How-Old.net Web page to Microsoft’s machine learning APIs to real-time  streaming analytics and real-time business intelligence . Altogether, this truly demonstrates the power of Azure services, they said.

“We wanted to create an experience that was intelligent and fun [and] could capture the attention of people globally, so we looked at the APIs available in the Azure Machine Learning Gallery,” Thompson and Balasubramanian said. “We found the ability of the face API to estimate age and gender to be particularly interesting and chose this aspect of it for our project. To make the experience more fun we used the face API alongside the Bing search API from the Azure marketplace to create http://how-old.net.”

The Machine Learning Gallery is home to intelligent service from the beta Project Oxford, which debuted at the Build conference earlier this week. Project Oxford helps developers create smarter apps that can do things like recognize faces and interpret natural language even if the app developers are not experts in those fields.

“If you are an app developer , you could just take the API capabilities and not worry about the machine learning aspect,” said Vijay Vokkaarne, a principal group program manager with Bing, whose team is working on the speech aspect of Project Oxford.

Beyond Age Guessing

We asked Rob Enderle, principal analyst at the Enderle Group, for his thoughts on the viral app. He told us this is clearly a blend of facial recognition, analytics and learning machines. With that in mind, what applications does it have beyond guessing our ages?

“We are likely to see more blends like this to help locate things on the Web, identify or analyze automatically problems at home, with our devices and cars, and at work, and give advice on what to wear to an event or to identify physical areas of concern early like skin cancer,” Enderle said. “We are moving into a time when ever more intelligent machines will be increasingly helpful in a proactive way and this is one of the showcases to that progress.”

After hinting about it for months, Google on Wednesday finally unveiled its Project Fi low-price wireless service. The service debuted two months after an announcement from Google saying that it would begin providing wireless connections to smartphones. The cost of the service is $20 per month, which covers talk, text, Wi-Fi tethering, and international coverage in more than 120 countries.

Project Fi will also only charge users for the actual data  they use instead rather than a flat rate. The rate for that data will be $10 per gigabyte. If a customer signs up for a 3-gigabyte plan but uses only 1 gigabyte during a month, the user will get a refund of $20 at the end of the month. That contrasts with the policies of most wireless phone service providers that allow users to carry forward their unused data but don't offer refunds.

Nexus Only

At first, Project Fi will be available only to owners of the Nexus 6 device that Google developed in partnership with Motorola Mobility. Users can buy Nexus 6 smartphones to use with Project Fi directly from Google when they sign up for the service. The midnight blue Nexus 6 is available in two storage  sizes: 32 GB for $649 and 64 GB for $699.

The Nexus 6 purchase comes with a payment plan for those who would rather not pay the full cost up front. Users can pay over 24 months at $27.04 per month for the 32 GB option or $29.12 per month for the 64 GB option, with no interest or fees. However, a credit check is required to be eligible for this pricing.

"Similar to our Nexus hardware program, Project Fi enables us to work in close partnership with leading carriers, hardware makers, and all of you to push the boundaries of what's possible," said Nick Fox, Google VP of communications products, on the company’s blog. "By designing across hardware, software  and connectivity, we can more fully explore new ways for people to connect and communicate."

Besides lowering prices for data, Google also said its Nexus devices will connect to the fastest network  available. Rather than building its own network, Google is leasing out tower space from companies like Sprint and T-Mobile, and it says Project Fi will automatically switch over to a Wi-Fi network if it is running at a higher speed than what’s available on cellular networks.

Early Access

Google said that with Project Fi, users’ phone numbers live in thecloud , so they can talk and text with those numbers on virtually any phone, tablet or laptop -- meaning that if a user’s phone gets misplaced, the connection can be maintained via another screen.

Google has initiated a Project Fi Early Access Program to invite people to sign up for the service. Customers who live where the program has coverage in the United States can request an invite at fi.google.com.

Less Apps Less Battery Consumption:

The lower number of apps installed on your Android device the more battery you can dig out from it. This is probably the best way to save a lot of battery. Dump all unnecessary apps that you had installed once but never used them again – remove them immediately.
Installing Battery Saving Apps:

These battery saving apps have profiles or modes in which that they can toggle Wi-Fi, GPS, Mobile data, Sync etc. They automatically turns on and off such things that drains battery. You can easily find these battery saving apps on Play Store.

Use task killing apps on your android:

There are some automatic task killers and some are manual. You can even set regular task kills. The more memory you have the more fast and responsive your device would be and would save battery life.

Select 2G in Network Mode:

Go in to settings/Wireless and networks/Mobile networks/Network mode and choose GSM only in Network mode. Because in Pakistan we only have GSM  — though we are desperately waiting for 3G but until then — changing such settings would also increase battery life.

Enable Sync or Uploading Only Through Wi-Fi:

Sync files or download large files through Wi-Fi only because this way such operations will take lesser time and hence lesser battery consumption.

Here are other parts that you should keep in mind to save the battery.

Disable Wi-Fi when not needed, Disable GPS when not needed, Disable Mobile data when not needed, Delete Unnecessary Widgets, Use Lower Brightness and Screen Timeout,  and the most important thing is Keep Your Device Cool.
