WhatsApp on web: 5 things it can’t do

fb-post NEW DELHI: With more than 700 million monthly active users, there's no doubt that WhatsApp is one of the largest mobile-focused messaging service. A large number of these users have been demanding a PC interface for the service to stay connected with their favourite people even when they switch devices. After a long wait, WhatsApp has finally introduced a way to access the service on a PC. However, there are several limitations attached to it as the interface is limited to a web browser.

Here are five limitations of WhatsApp for web...

1. It doesn't support iPhone: WhatsApp for web essentially syncs messages between your smartphone and browser via its servers. At this time, the service does not support the iPhone. According to WhatsApp it's unable to provide the web client to iOS users due to Apple's platform limitations. Reports indicate that it intends to support the iPhone in the future but till then, if you use WhatsApp on an iPhone, you'll need to peep into your phone every time you get a WhatsApp message even if you're in front of your computer.

2. Needs your phone to be on and connected to the internet: After pairing your smartphone with WhatsApp's web client through a QR code image, you'll be able to send and receive messages through your browser. But what if your phone loses the data connection or runs out of charge? Sadly, the WhatsApp web version will also go offline. Your phone needs to stay connected to the internet for the web client to work.

3. Doesn't support browsers other than Google Chrome: WhatsApp's web interface only supports Google Chrome. So if you use Firefox, Safari or Internet Explorer, you're out of luck. A number of IT environments restrict the use of applications not approved by admins. If you're part of one and can't use Chrome, you'll not be able to use WhatsApp for web. WhatsApp's justification is that Chrome's push technology is better.

It's surprising that the service doesn't support Internet Explorer given Microsoft's investment in Facebook which owns WhatsApp. Also, it's worth pointing out that Google (the developer of Chrome) competes directly with Facebook.

4. You can't block users: To block users, you still need to go to the WhatsApp mobile app. The number of spam messages on WhatsApp has gone up considerably and the only way to deal with these, is to block their number. Unfortunately, the web version does not offer the block feature.

5. You can't create and leave groups: While you can send and receive messages from groups you're a part of, the WhatsApp web client doesn't let you create new groups or leave existing ones. You also can't send broadcast messages via the web client.

True Caller hacked, 1 million Indians’ data at risk

Global phone directory app True Caller has been hacked by activist group Syrian Electronic Army (SEA). The hacking group announced this in a post on Twitter, along with an image that showed details of some users of the app.

Syrian Electronic Army broke the news via a tweet saying, "Sorry @True Caller, we needed your database, thank you for it." The hackers openly released True Caller's database host ID, username and password via another tweet.

True Caller app is available on Android, iOS, Windows Phone, BlackBerry and Symbianplatforms. The app's databases have access codes to Face book, Twitter, LinkedIn and Gmail accounts of millions of users globally. Reports say that True Caller website went down for a while but is now back online. In June this year, True Caller announced that its user base has touched the 20-million mark, representing growth of 100% in a period of five months. It said that it has 1 million users in India in March.

The Syrian hacking collective revealed that it exploited the TrueCallerwebsite as it is based on outdated Word press platform, which gave them access to the admin panel. Speaking to E Hacking News, the SEA hackers said that they have hacked into the phone directory's servers and downloaded more than seven databases. The biggest database has data worth 450GB.

Syrian Electronic Army is behind several high profile hackings, including those of Associated Press, BBC and The Onion.

First look: Google versions of HTC One, Galaxy S4

photo_1373210579_temp.jpg.pagespeed.ce.nzEcg30QsN[1] NEW YORK: Two new Android phones will look and sound familiar to those who have been paying attention to phones. That's because these two devices are replicas of Samsung's Galaxy S4 and HTC's One, except they lack most of the bells and whistles added to the original models. 

And that's a good thing.

The modifications Samsung and HTC apply to Google's Android software are meant to be improvements. But I've complained before about how the changes actually make phones more complex to use. The S4 even has an easy mode for first-time Smartphone users, an admission that the normal mode is too confounding.

JMD COMPUTER India - Outsourcing Website Development India - website development India - e commerce development India

Google worked with both Samsung Electronics and HTC to come out with "Google Play" editions of the hit phones. Instead of customized software Samsung and HTC, the Google phones run a pure version of Android, just as it was developed by Google.

Google lets any phone maker use its Android operating system for free. To set themselves apart competitors, phone makers often add their own touches to devices. They rearrange the menu or load additional apps. Wireless carriers also to add their own apps. Before you know it, phones are bloated with features and apps you don't want and can't get rid of.

Consider my experience with the original S4 over the weekend. As I tried to adjust the camera's flash setting, I inadvertently made some postage stamp icon pop up. That activated the camera's dual-shot mode, which snaps a shot of you with the front camera to superimpose over whatever you're shooting with the camera on the back of the phone. I didn't want that, but I couldn't figure out how to get rid of it. My friend couldn't either. So we bagged the shot. Taking photos with a phone is supposed to be fun, not a chore.

With Google's version of the S4, I get a no-frills camera that is easy to figure out. It lacks gimmicks such as dual shots and the ability to combine several images of motion into a single shot. It offers about a half-dozen shooting modes, such as night, action and panorama, rather than the dozen or so on the original S4. But a half-dozen is about a half-dozen more than I need and use.

Google's S4 also lacks the original model's ability to pause video automatically when you look away the screen or to scroll down an article when you tilt your head. Those features may sound cool, but they often don't work properly.

The Google version of the S4 also has alarm sounds that I can actually wake up to. Samsung had substituted those sounds with soft, soothing melodies that I end up incorporating into dreams. I've overslept a few times as a result.

As for Google's version of the HTC One, you don't get a busy home screen filled with news articles and Facebook status updates your phone thinks you want to read. Instead, you get a clean page with few apps. It's up to you to add the ones you want to see and use.

JMD COMPUTER India - Outsourcing Website Development India - website development India - e commerce development India

Both Google phones feel spare and minimal, which is great because it makes me feel in control. If I want to constantly know the weather, it's easy to add a weather widget to the home screen of either phone. But it's not forced.

The same goes for apps. I get basic functions such as text messaging and the clock and a range of Google services such as Gmail and YouTube. If I want other apps, I can easily tap the Google Play icon to get them. With the original S4, Samsung tries to steer you into its own app store, as well as its own music and video players. You end up with too many ways to do the same things.

You might think it takes a lot of work to add the apps you want to Google's phones, but it actually takes more work to hide or turn off everything you don't need - that is, if you can at all- with Samsung's and HTC's versions.

Now for the bad news: The Google edition of the S4 sells for $649, while Google's HTC One goes for $599. You can typically get the original models for $100 to $200 through your wireless carrier with a two-year agreement. And unless you're on T-Mobile, your monthly bill won't go down just because you pay full price for the phone elsewhere.

JMD COMPUTER India - Outsourcing Website Development India - website development India - e commerce development India

In addition, both Google phones are compatible only with T-Mobile, AT&T and other carriers that use GSM cellular technology, not the CDMA networks used by Sprint and Verizon Wireless. The Google edition would have been great for Verizon customers who still have unlimited data plans. Verizon no longer lets you stay on that plan if you buy a subsidized phone, so you'd have to pay the full price anyway.

The Google phones are also ideal for people who want the latest Android system that Google has to offer. You'll be able to update your phone as Google releases new versions of Android. Normally, phone makers and wireless carriers updates by weeks or months, so you can only read about those new Android features.

There are a few useful Samsung and HTC add-ons that Google does bring to its versions of the phones.

Google's S4 is compatible with Samsung's S-View flip cover. Using a magnetic sensor, the phone detects when the cover is closed and switches to a special mode that gives you the current time and details about who's calling through a small window in the cover. You can answer or reject a call without flipping over the cover.

Google's HTC One, meanwhile, shares the original model's front-facing speakers, giving you great sound when you're watching a movie or listening to music. Both models also have cameras with larger sensor pixels for better low-light shots. Our tests show that the HTC One produces low-light images with less distortion than other Android phones, though images aren't particularly crisp because the resolution is lower.

There are a few things I wish Google would have brought to its phones and to Android in general.

In the original S4, the on-screen keyboard has a row of numerals to type in. With the Google S4, you have to hit a button to get another screen with numerals, then toggle back for the letters. The original S4 also has the ability to run two apps side by side in a split window. That's gone in Google's S4.

Meanwhile, the original HTC One has the ability to make calls, send texts and take photos by sliding icons the lock screen. With the Google version, you have to unlock the screen before getting icons to those functions.

On both phones, Google also adds one feature I could do without: a 360-degree panorama known as Photo Sphere. Neat as it is, it detracts what is otherwise a just-the-basics camera. It would have been better as a separate app for those who want it.

But that's no reason to shun the Google phones. The minimized feel of Google's versions underscores how busy software can detract good hardware. Take away that clutter, and you have excellent phones.

It's a bummer that you can't get the simplified phones through regular channels. You can get them only through Google's online Play store - for hundreds of dollars more.

About the Google phones

The new phones are existing Samsung and HTC phones loaded with Google's version of the Android operating system. That's the version that Google makes, before phone makers and phone carriers load Android up with their own features and apps.

JMD COMPUTER India - Outsourcing Website Development India - website development India - e commerce development India

These phones are good options for those who don't all the bells and whistles in the original models. They are cleaner and easier to use. But they are also more expensive, as you have to pay full price through Google's online Play store rather than a subsidized price that wireless carriers offer with two-year agreements.

These phones aren't compatible with Verizon's or Sprint's CDMA networks. If you're on AT&T, you'll be paying more for the phone without any reduction in monthly phone bills. If you're on T-Mobile, though, expect to save $20 a month, or $480 over two years. You're still paying about $70 more overall for Google's S4 and $20 more for Google's One, but it's not the hundreds of dollars you'd be paying on AT&T.

The one-time, upfront cost is $649 for Google's S4 with 16 gigabytes of storage and $599 for the One with 32 gigabytes. Both phones are available in the US only through Google's online Play store, with shipments expected by July 9.

See, what makes your Android phone vulnerable to hackers

LONDON: A 'master key' has been reportedly discovered by a security research firm which could potentially give cyber attackers access to almost every Android phone.

According to BBC, security research firm BlueBox has discovered the loophole which is present in every version of the Android operating system released since 2009.

The bug emerges as a result of the way Android handles cryptographic verification of the programs installed on the phone

The report said that Android uses the cryptographic signature as a way to check that an app or program is legitimate and to ensure it has not been tampered with.

Jeff ForristalBlueBox and his colleagues have found a method of tricking the way Android checks these signatures so that malicious changes to the apps go unnoticed.

Forristal said that the implications of this discovery could be 'huge' as it can take over the normal functioning of the phone and control any function thereof.

Security expert Dan Wallach said that in order to catch Android users, malicious hackers would have to get their booby-trapped version of a legitimate application on to the Google Play store.

According to the report, BlueBox had reported finding the bug to Google in February.

Google denied commenting on BlueBox discovery, the report added.

Samsung Galaxy S4 may have unbreakable screen

photo_1354791822_temp.jpg.pagespeed.ce.80N80ykNTd Samsung Electronics, the world's leading technology company by revenue, is likely accelerating the launch of its next-generation flagship Galaxy smartphone -- which may come with a breakthrough unbreakable screen.

Codenamed "Project J" after mobile division chief JK Shin, development of the new Galaxy S IV could be aimed for release by as early as April, according to analysts and tech blogs.

And, as smartphones increasingly look alike - the converging form factor - an unbreakable screen could be a big selling point for the Galaxy, which is battling Apple Inc's iPhone to lead the $200 billion plus smartphone market.

The Galaxy S IV is also expected to have bigger and better display, powerful quad-core processing power and a 13-megapixel camera, with picture density improving to 441 pixels per inch (ppi), a big improvement from the Galaxy S III's 306 ppi and better than the iPhone 5's 326 ppi.

"Looking to the first half of 2013, we see evidence of Samsung likely accelerating the release of the Galaxy S IV - compared with May (this year) for the Galaxy S III," said UBS analyst Nicolas Gaudois. "We believe preparations for volume manufacturing of unbreakable plastic substrate displays continue. All in all, we could see a strong products push in the high-end in the first half, followed by other releases."

Samsung declined to comment.

Samsung, a major backer of organic light-emitting diode (OLED) display, is a frontrunner in developing unbreakable screens, as OLED panels can replace glass substrate with plastic material. Down the road, mobile gadgets could be flexible as well as unbreakable.

"Eventually, they'll have unbreakable and flexible displays. Either the Galaxy S IV or S V will have unbreakable and even possibly flexible and foldable displays by 2014. That's going to be a game-changer," said Mark Newman, an analyst at Stanford Bernstein in Hong Kong.

Both Newman and Gaudois are ranked as 5-star analysts, the top ranking, by Thomson Reuters StarMine for their recommendations on Samsung.

Courtroom revisited

It would also be a game-changer for Samsung, which has built its reputation as a 'fast follower' of others' technologies and designs.

The South Korean consumer electronics giant faces off against Apple again on Thursday in a US courtroom for a follow-up ruling on whether it copied some of its US rival's patents and should pay the $1 billion awarded to Apple by jurors in an August verdict.

Samsung wants the verdict overturned, while Apple wants the damages to be increased and Samsung phones banned in the United States.

Since that landmark verdict, however, Samsung shares have gained 14 percent to record highs, while Apple shares - dented by a maps app fiasco, tight supply of its iPhone 5 and ever tougher competition in the mobile market - have slipped by nearly a fifth, wiping more than $120 billion off its market value.

Barring any extra costs related to the US ruling, Samsung should report a fifth straight record profit this quarter, as profits from its component business recover and more than offset thinning margins on mobile phones - squeezed by higher year-end holiday marketing campaigns.

"Samsung's strength extends beyond cool products, they're also a leader in the technology behind these devices. We see further upside to Samsung's stock as success in smartphones continues and chips and display profits also rebound," said Newman. "In smartphones, the opportunity is for Samsung to take more share from Apple in the premium segment, where Apple is still dominant."

UBS estimates Samsung will ship around 22.5 million of its Galaxy S III and Note II devices in the quarter to end-December, up from 20 million in July-September. Shin said in November that Galaxy S III sales would hit 40 million by the end of this month.

In a worst-case scenario for Samsung, US judge Lucy Koh could treble the damages payable to Apple, given the jury in August found Samsung "willfully" infringed some Apple patents.

"That would be a major blow to Samsung's fundamentals and overall investor sentiment, but it's not the most likely scenario," said Young Park, a 4-star StarMine analyst at Woori Investment & Securities.

DoT issues new rules for buying SIM cards

simcard-jmdcomputer Taking new mobile phone connection from will require physical verification of facts provided by subscribers and submission of forged documents will lead to police inquiry.

Tougher guidelines by the Department of Telecom, which took effect, make operators responsible for inaccurate information provided by subscribers for taking new pre-paid and post-paid mobile connections.

Under the new rules, the authorized person selling SIM cards will have to give an undertaking that he has seen the applicant and matched the photograph attached on the application form.

Retailers and franchisees selling mobile SIM cards will have to register police complaint against subscribers if they submit forged documents to get the connections.

All the telecom operators across the country are required to comply with the new guidelines.

"By and large we are compliant with most of the norms though there are a few areas for which we have sought clarifications from DoT like verification of date of birth and age," GSM industry body COAI director general Rajan S Mathews told PTI.

He said the government has indicated that the operators have to verify certain documents which include date of birth and age of users.

"We have asked DoT what should we do in case if the user has no documents related to his date of birth," he said.

COAI is expecting a reply on the issues in the next few days.

Samsung fined Rs 10,000 over faulty phone

xphoto_1351564749_temp.jpg.pagespeed.ic.8QA_ARkRYs Samsung India has been asked by a consumer forum to pay Rs 10,000 to one of its customers for selling him a faulty mobile phone and then failing to get it repaired.

The compensation was awarded by the Central Delhi District Consumer Disputes Redressal Forum after Samsung offered to settle the matter by paying Rs 10,000 to complainant Mulk Raj Manchanda.

"We have examined the record and have found that the instrument, purchased by the complainant (Manchanda), has not given him due service/facilities. The same could not be repaired by the seller as well as by the service provider of Samsung India Electronics Pvt Ltd."

"We are of the view that the amount of Rs 10,000 as offered by opposite party three (Samsung) will be sufficient to meet the claim of the complainant in all respect, including the purchase cost of the mobile phone as well as compensation and litigation charges.

"We allow the complaint with the direction to Samsung to pay the complainant Rs 10,000 on returning the mobile phone by him to opposite party 3," the bench presided by B B Chaudhary said.

In his complaint, Manchanda had alleged the Samsung mobile phone which he had purchased on December 29, 2009 for Rs 5,300 did not function properly and had a faulty battery.

He had also alleged the Samsung's authorised dealer from whom he had bought the phone had assured him that if the device gave any trouble then free service for five years would be available and if the trouble persists, the mobile handset would be replaced.

Samsung Galaxy S3 & wireless charging: How it works

While announcing Galaxy S3 at an event in London, Samsung said the device would support wireless charging when used with a special charger that would be sold separately.

This brings up a question: How does wireless charging work? Among the engineers and scientists, wireless charging is known as 'inductive charging'. It utilizes two smart coils - one in the charger and another in the device that is getting charged. The primary coil creates a very small electromagnetic field around the charger through which electricity can be transferred. The secondary coil, which is in the phone, receives the power from electromagnetic field and converts in back into electric current to feed it into the battery.

The technology is still in the early stages and it works best when the distance between the two coils is few millimeters. That's the reason why users have to place the device on the charger.

JMD COMPUTER India - Outsourcing Website Development India - website development India - e commerce development India

The main benefit of wireless charging is that it removes one more wire. This not only makes it easier to charge the phone but also has aesthetic appeal. At the same time, wireless charging has poor efficiency. This means it takes longer to charge the battery through wireless charger.

Galaxy S3 is not the first phone to use wireless charging. Three years ago Palm commercialized the technology and sold a charger called Touchstone that allowed phones like Pre and Pixi to be charged wirelessly. Powermat is another company that sells special chargers, which can be used with iPhone and other devices for wireless charging.

After introducing the technology in 2009, Palm supported it in almost all of its devices. Even Touchpad, which was introduced in the market last year after Palm had been acquired by HP, had this feature. Of course, Palm is dead now.

There is a chance that Samsung is doing things differently. But that is not apparent. The company says that to charge Galaxy S3 wirelessly, users will have to keep the device on the 'special charger'. This is exactly how Touchstone worked.

Samsung Galaxy S3: wireless charging a possibility

imageReports from Korea suggest the Samsung Galaxy S3 may come with wireless charging capabilities allowing you to say goodbye to that fiddly night-time plug in ritual.

According to an anonymous source, Korean publication DDaily says it has been told that the hotly-anticipated Galaxy S3 will allow users to do away with wires as it will arrive with a built in inductive charger.

The source goes on to say that the Galaxy S3 will be able to charge from a distance of 1-2 meters from the charger base.

Look mum, no wires!

Wireless charging is nothing new, with a variety of cases and charging mats currently available on the market to suit a range of handsets and built in wireless charging technology has had its outing in the form of the Palm Pre among others.

JMD COMPUTER India - Outsourcing Website Development India - website development India - e commerce development India

The hope is if Samsung manages to squeeze this technology in a handset, which is already rumoured to boast a quad-core processor, 4G connectivity, HD screen, NFC and a decent camera, it will have refined the process making it more efficient and cost effective.

Being able to charge your phone by just placing it down somewhere near a plug is certainly appealing, but if the base station is not included in the box (which we reckon is more than likely) we still expect a substantial cost to be involved to pick one up.

We're taking this latest report with two large fistfuls of salt, as it would seem unlikely Samsung will be able to keep the weight and depth of the Galaxy S3 down to a reasonable level with all the touted tech it's expected to pack into it.
