Samsung Galaxy Tab 3 series: First impressions




 feel cheap at all. One thing that we noted here is that all products under the Galaxy range have started to look similar in design and the only difference is the form-factor and the sheer size of the display.

All the tablets in the Galaxy Tab 3 range share the same design. They all run Android Jelly Bean, and each tablet features a physical home button accompanied by two capacitive Menu and Back keys on either side.

The same layout is featured on Samsung's high-end and even low-end devices, and it looks like the Korean giant is adopting it as its universal design concept. However, we were not disappointed as we feel the physical Home key is very useful at times. The Galaxy Tab 3 211 with a 7.0-inch display can easily be used with one hand thanks to the slim design and less weight.

Google Chromebook Pixel review




Google's first high-end laptop, the Chromebook Pixel, is an impressive machine. It feels light and comfortable in my hands and on my lap. Its high-resolution display makes photos look sharp and video come to life. From a hardware standpoint, it's everything I'd want a laptop to be.
But the Pixel isn't very practical at least not yet - for most people. It works well when you have a steady Internet connection, but can't do much once you lose that connection. And because it uses Google's own operating system, it doesn't run enough software yet to replace your other machines.

I brought the Pixel along for a nearly three-week trip to Thailand and Cambodia, where I knew I wouldn't have the type of round-the-clock access I'm used to in the U.S. I was surprised by how much I could do, but quickly got frustrated when I couldn't do more.

Such frustration doesn't come cheap. Prices for the Pixel start at $1,299, just $200 less than a MacBook with a comparable screen and the ability to do much more offline. A higher-end Pixel with cellular access costs $150 more than the basic model and is scheduled to start shipping Monday.

For those unfamiliar with Google's entry into the laptop market - I guess that's many of you - the Pixel and other Chromebooks run a Google operating system called Chrome OS. Based on the Chrome Web browser available for Windows and Mac computers, Chrome OS underscores Google's vision of letting the Internet do all the heavy lifting instead of your computer.

As a result, you can power up and start working on the Chromebook right away. Boot time is minimal because there's not a lot of software to load. Those functions are pulled from the Internet as needed. That also means updates come regularly and don't need any installation on your part.

There's not a lot of storage on the machine either. The idea is to keep as much as you can online, through a storage service such as Google Drive or Dropbox.

Think of the Chromebook as a gateway to the Internet. You can download apps from Google and others to run on the Chromebook, but many of those apps do little more than access a website on your Chrome browser when you're online.

Previous Chromebooks haven't been too powerful. They have tended to be low-cost machines ideal for casual users who mostly need computers for Internet tasks such as email and Facebook.

Google is changing the dynamics with the Pixel. It's targeting power users who are willing to pay more money for the best features.

For $1,299, you get a well-built machine sporting a touch-sensitive display that measures nearly 13 inches (33 centimeters) diagonally. The screen's resolution is among the best out there. At 239 pixels per inch, it tops the 227 pixels per inch on the 13-inch MacBook Pro, though your eyes might not be able to discern that small difference.

The basic Pixel model comes with 32 gigabytes of storage and has a slot for external storage, such as a camera's SD card. Each machine also comes with a three-year subscription for 1 terabyte of online storage through Google Drive. It's normally $50 a month.

Google also offers a $1,449 model that has double the internal storage, at 64 GB, and 100 megabytes a month of LTE cellular data access through Verizon Wireless for two years. That's suitable for occasional use, but if you'll be away from Wi-Fi a lot, you'll need a data plan. Prices start at $10 a day.

The LTE model isn't set to ship until Monday, but Google lent me one to try out. I was impressed with the LTE offering, as the cellular access would help cover some of the gaps I'd have outside my home and office. But it's of no use abroad.

Nor is LTE of use on airplanes. Both models offer 12 free sessions with Gogo's Wi-Fi service on airplanes, but those are good only for flights that offer that capability. Those tend to be domestic flights in the U.S.

So I found myself trying to use Chromebook without a steady Internet connection.

Before I left, I configured the Chromebook browser to enable offline access to Google Docs, the company's set of online tools such as word processing and spreadsheets. With offline access, you're able to access and edit documents. Changes get synced with the online versions the next time you connect to the Internet.

I was able to do a fair amount of writing offline, but every now and then, my document would disappear, replaced by Google's "Aw, Snap" error message sporting a sad face icon. That would be cute if hours of work weren't at stake.

Although I was usually able to recover the file and never lost more than a paragraph of writing, I got nervous with every crash. Google Docs lets you save copies on your computer as text files or in Microsoft's Word format. But that function works only when you are online, even for changes you are making offline.

Even without the crashes, I wasn't getting tools such as spell-checking while offline. That's not an issue when using Word or Apple's Pages on other machines.

Beyond text documents, the Chromebook is able to view photos, PDFs and other files, just like any other computer. It can also read files in Microsoft's Word and Excel formats, though you must convert them to Google Docs to make changes.

And obviously, it can browse the Web. I successfully paid credit card bills, bought magazines and watched Hulu video on the Pixel. I was able to read an e-book on Amazon's Web-based Kindle app, too.

But there are limits, particular when sites require plug-ins that aren't available for the Chromebook.

And while I was able to write this story on a Chromebook, our publishing system isn't compatible with it.

Chromebooks are ideal for those who have steady Internet access and do most of their computing on Web browsers. But those people may be fine with one of the other, much cheaper Chromebooks. One is the $249 Samsung Chromebook, which I have tried and like for simple tasks when Internet access isn't an issue.

If you need a machine as powerful as the Pixel, you might also need an operating system that can do more, especially when offline.

Google executive Caesar Sengupta admits that Chromebook owners might still have to turn to a Windows or Mac computer now and then. In many ways, it reminds me of the early days of the Mac, when most software was written only for Windows.

That makes the Pixel expensive for a machine that can't serve as your sole computer. At $1,299, I'd rather spend another $200 for a MacBook with a high-resolution display and four times the storage, at 128 gigabytes. You don't get a touch screen with the MacBook, but frankly, I didn't use the Pixel's touch controls even once during my Asia trip.

On the other hand, Sengupta told me that selling Pixels isn't Google's main goal with the machine. Rather, the company made it to showcase Google's vision for the future of computing. In that case, Google has succeeded in producing a machine that is a pleasure to use - as long as you're online.

About the Chromebook Pixel
The device represents Google's entry into the high-end laptop market. It runs Google's Chrome OS operating system, which largely assumes you'll have round-the-clock Internet access. You can still work with the device offline, but functionality is limited.

The basic model costs $1,299 and comes with 32 gigabytes of storage. For $1,449, you get 64 gigabytes and LTE connectivity through Verizon Wireless. Both models come with a terabyte of online storage through Google Drive for three years, a $1,800 value at $50 per month. Not everyone will need as much storage, and Google Drive offers free and cheaper plans.

The pricier Pixel model also offers 100 megabytes a month of LTE cellular data access through Verizon Wireless for two years.

If you need more, you can buy a day pass with unlimited data for $10. Or you can buy 1 gigabyte of data for $20, 3 GB for $35 or 5 GB for $50. Those are good for a month. If you're a Verizon customer with a plan for sharing data allotments over multiple devices, you can add the Pixel for just $10 a month.

HTC One launch fails to prevent sharp decline in HTC's profits

Sales of the flagship HTC One phone appear to have helped the Taiwanese smartphone maker recover from a tough first quarter, but profits are still sharply down year on year.

Revenue for HTC's second financial quarter fell 23 percent year-on-year to NT$70.7bn ($2.3bn), according to its unaudited results. Operating income dropped to NT$1.05bn ($30m), a 87 percent fall compared to Q2 2012, and net income before tax fell to NT$1.52 ($50m), a year-on-year fall of 83 percent.

In contrast, Q2 operating income is well up on Q1 when operating income fell to NT$43m, the company's lowest quarterly profit since 2004.

Helping this quarterly recovery was the launch of the HTC One around the end of March this year, when it received largely positive reviews praising its build quality and fast quad core processor.

However, HTC's Q2 profits were below analyst forecasts and a recent research note from BNP Paribas predicted that third-quarter earnings are not expected to see a significant rise.

"HTC may have new products in Q3, but competition from Apple and other Chinese brands are fierce," said Taipei-based analyst Peter Liao, of Nomura Securities. "It'll be hard to keep the growth."

The smartphone maker has a number of products in the pipeline, with the mid market One Mini phone expected to launch in August ahead of handsets from competitors Samsung and Apple.

HTC was the world's 10th-biggest smartphone maker by shipments in the fourth quarter of 2012, according to analyst house Gartner.

Samsung galaxy s4 tips and tricks


Android 4.3 on samsung s3


Android 4.3

Spotted first by Samsung focused website, Sam Mobile, the screenshots of the phone's 'About phone' page show the model number as GT-I9505G, which hints that the phone is the Google edition of the Qualcomm Snapdragon 600-powered Galaxy S4. The phone's build number is JWR66N.S005.130625 in which JWR66N depicts the Android build while S005.130625 is Samsung's internal naming convention for test builds.

The site has also posted a screenshot of the Camera app which sports an updated user interface. The new Camera app's options are more accessible than they are in the current stock camera app. The controls for HDR, exposure adjustments, settings and flash among others are placed in a curved line together.

Interestingly, the same updated camera app is included in the Android 4.2.2 build for the Samsung Galaxy S4 and HTC One stock Android, Google edition variants.

We had earlier seen the same camera app when a Nexus 4 running Android 4.3 was spotted at the Thailand Mobile Expo, last month. So, it's possible that the Android 4.3 will bring the updated camera app, and Samsung was given early access to include it in Android 4.2.2 build of the Galaxy S4.

Besides the updated camera app, Android 4.3 is also expected to feature native support for Bluetooth Smart Ready technology. The Bluetooth Special Interest Group in a press statement earlier confirmed that Google had committed to bringing support for Bluetooth Smart to future versions of the operating system. Bluetooth Smart allows compatible phones to take advantage of low power consumption with Bluetooth Smart ready devices like the Fitbit Flex or Pebble mart watch. The statement had said that the newest version of Android OS natively supports Bluetooth Smart Ready technology.

While Google was expected to announce Android 4.3 during the Google I/O keynote, it chose to skip the announcement and instead made a slew of service and developer related announcements including new features for Google+, the Hangouts unified messaging app, updated Maps, Google Play for Education, a music streaming service,and updated Search among others. Another report had claimed that Google would release Android 4.3 on June 10 along with the White colour variant of the Nexus 4 phone, but that did not materialise either.

HTC desire 600 dual sim support with quad core processor

HTC Desire 600 sports a 4.5-inch Super LCD2 display of 540x960 pixels resolution and is powered by a 1.2GHz Snapdragon 200 quad-core processor alongside 1GB of RAM and 8GB of expandable storage. It comes with an 8-megapixel rear camera and a front-facing 1.6-megapixel shooter.

Running the dual-active system, the HTC Desire 600 allows you to have two SIM cards active all the time, enabling you to receive a call on one line, even if you are already using the other.

The dual front-facing speakers of the HTC Desire 600, complete with built-in amplifiers offer a sharper smartphone sound, that HTC labels 'BoomSound'. Beats Audio integration is included as well.

The phone runs Android 4.1 Jelly Bean with HTC Sense 5.0 on top with BlinkFeed and other software features, seen earlier with the HTC One. HTC Desire 600 comes with a 1860mAh battery and connectivity options include Bluetooth 4.0, Wi-Fi, GPS and 3G.

Aakash tablet 2 review


Aakash 4 to come with 4g support and voice calling

The next model of low-cost tablet under Aakash project will possess calling facility and high speed 4G services support, as per specifications released by government.

The specifications released by government suggest it will have "Driver for Phone Functionality with external dongle" and support "Data functionality with external 2G or 3G or 4G dongle".

The Aakash project was Telecom Minister Kapil Sibal's brainchild when he was the HRD Minister. The idea is to provide low-cost computing device at subsidised rate to students so that they can access Internet for educational purposes.

The first version of the tablet was launched on October 5, 2011. The tablet PC then launched had basic feature and costed government around Rs. 2,276. Government later upgraded the tablet with some advance features at the same price.

The latest version will have multiple new features but the the final price of the tablet has not been disclosed.

The new version of the tablet will have Bluetooth in-built which was missing in the previous versions. Other specifications included in the document posted online include minimum 1GB RAM, 4GB internal storage (expandable up to 32GB), 7-inch 800x480 display, Wi-Fi 802.11 b/g/n.

The document says the Aakash IV tablet should be able to minimum 3 hours of 720p video on a single charge and the battery should be able to hold at least 90 percent of its charge after 30 days of standby time (tablet is turned off).

Software wise, the document mentions the tablet should come with Android 4.2.1 (Jelly Bean) or above, and should be able to dual-boot Linux stored on an external card.
