Camera megapixel war in smartphones: Picture perfect or just a gimmick?

In 2012, Nokia, which was at the top of the mobile industry, brought 808 PureView, a Symbian operating system (OS)-based smartphone with an insane 41MP camera that created quite a buzz.

Since then, Android-based smartphones started gaining traction and original equipment manufacturers (OEMs) began adding more megapixels to the cameras to lure the crowd.

Now Chinese smartphone makers have sounded the bugle for a megapixel war and the users are in for some sweet deals as camera sensors grow in specifications at affordable price points.

In India, Realme, which initially started off as a subsidiary of Chinese handset maker OPPO, became the first to introduce a 64MP camera smartphone -- Realme XT -- few weeks ago followed by Xiaomi, which has recently unveiled its Redmi Note 8 Pro with 64MP.

Samsung has even created a 108MP sensor for upcoming smartphones.

As many as 50 per cent of smartphones sold globally will have three or more camera sensors by the end of 2021, says Counterpoint Research.

According to industry experts, it is an attempt by the brands to differentiate themselves from competition and remain at the top of the consumers' mindshare.

"It should be seen as a marketing plank, which enables brands to showcase innovation for a feature which is important for smartphone consumers these days," Navkendar Singh, Research Director-Devices and Ecosystem, India & South Asia, International Data Corporation (IDC) told IANS.

These numbers indicate the availability of the sensor size at a cost that can let smartphone brands bring it in a model at affordable price points.

"In early 2020, we should expect launches with 92MP and 108MP in the market. Beyond a certain megapixel capability, a normal consumer cannot feel the difference in the photograph purely from a megapixel viewpoint," Singh noted.

According to Counterpoint Research, Xiaomi was at the second spot with a 17 per cent share in the Rs 15,001-Rs 20,000 price segment in India in Q2 2019, while Realme ranked sixth with 6 per cent share in the same period.

However, Realme inched up to the fourth position with 12 per cent market share, whereas Xiaomi slipped to the fifth spot with a share of 9 per cent in July-August.

"In Q2 2019, 14 per cent smartphones shipped with 48MP lens cameras and 70 per cent with two or more rear cameras.

"However, merely adding a bigger megapixel sensor does not determine higher picture quality," Karn Chauhan, Research Analyst at Counterpoint Research told IANS.

There are multiple factors, such as the lens, the size of the aperture, Image Signal Processor (ISP), software algorithms, AI, etc. which come into play while determining the quality of the picture.

"The tech advancements, exemplified by Samsung eISOCELL Bright GW1', the 64MP image sensor, used by the likes of Realme and Xiaomi, are essentially pushing the envelope for better, low light HDR photography and brighter, detailed photographs mimicking very closely the human eye vision," Prabhu Ram, Head, Industry Intelligence Group (IIG), CMR, told media.

Giving each and every app access to personal information stored on Android smartphones such as your contacts, call history, SMS and photos may put you in trouble as bad actors can easily use these access to spy on you, send spam messages and make calls anywhere at your expense or even sign you up for a premium "service", researchers from cybersecurity firm Kaspersky have warned.

But one can restrict access to such information as Android lets you configure app permissions. 

Giving an app any of these permissions generally means that from now on it can obtain information of this type and upload it to the Cloud without asking your explicit consent for whatever it intends to do with your data.

Therefore, security researchers recommend one should think twice before granting permissions to apps, especially if they are not needed for the app to work. 

For example, most games have no need to access your contacts or camera, messengers do not really need to know your location, and some trendy filter for the camera can probably survive without your call history, Kaspersky said. 

While decision to give permission is yours, the fewer access you hand out, the more intact your data will be.

Here's what you should know to protect your data.

SMS: An app with permission to send and receive SMS, MMS, and WAP (Wireless Application Protocol) push messages, as well as view messages in the smartphone memory will be able to read all of your SMS correspondence, including messages with one-time codes for online banking and confirming transactions.

Using this permission, the app can also send spam messages in your name (and at your expense) to all your friends. Or sign you up for a premium "service." You can see and conrol which apps have these rights by going to the settings of your phone.

Calendar: With permission to view, delete, modify, and add events in the calendar, prying eyes can find out what you have done and what you are doing today and in the future. Spyware loves this permission.

Camera: Permission to access the camera is necessary for the app to take photos and record video. But apps with this permission can take a photo or record a video at any moment and without warning. Attackers armed with embarrassing images and other dirt on you can make life a misery, according to Kaspersky.

Contacts: With permission to read, change, and add contacts in your address book, and access the list of accounts registered in the smartphone, an app can send your entire address book to its server. Even legitimate services have been found to abuse this permission, never mind scammers and spammers, for whom it is a windfall.

This permission also grants access to the list of app accounts on the device, including Google, Facebook, and many other services.

Phone: Giving access to your phone means permission to view and modify call history, obtain your phone number, cellular network data, and the status of outgoing calls, add voicemail, access IP telephony services, view numbers being called with the ability to end the call or redirect it to another number and call any number.

This permission basically lets the app do anything it likes with voice communication. It can find out who you called and when or prevent you from making calls (to a particular number or in general) by constantly terminating calls. 

It can eavesdrop on your conversations or, of course, make calls anywhere at your expense, including to pay-through-the-nose numbers, Kaspersky warned.

In a first, the Supreme Court on Friday allowed the service of summons and notices, a necessity in almost all legal proceedings, through instant messenger like WhatsApp as well as by e-mail and fax.

A bench headed by Chief Justice SA Bobde observed that it has been brought to the notice of the court that it is not feasible to visit post offices for service of notices, summons, and pleadings. The bench also comprising Justices AS Bopanna and R Subhash Reddy observed that notice and summons should be sent through e-mail on the same day along with instant message through WhatsApp and other phone messenger services.

The bench clarified that all methods should be deployed for a valid service on the party. "Two blue ticks would convey that the receiver has seen the notice," noted the bench.

The bench declined the request of the Attorney General for specifically naming WhatsApp as a mode of effectuating service. The top court noted that it would not be practical to specify only WhatsApp. The apex court also permitted RBI to extend the validity of cheques in the backdrop of lockdown to contain the coronavirus outbreak.

Senior advocate V Giri representing RBI informed the bench that he had circulated the note regarding validity of a cheque as directions issued on the previous hearing.

The bench noted that it will be in discretion of the RBI to issue orders which are suitable to alter the validity of the period of a cheque.

During an earlier hearing on the matter on July 7, the Attorney General contended before the top court that the Centre had some reservations in connection with the utilization of mobile applications like WhatsApp and other apps for service of summons. The Centre's top law officer informed the apex court that these apps claimed to be encrypted, and they were not trustworthy.

The RBI counsel had contended before the top court that it was considering clarifying the validity of a cheque which has been reduced to 3 months from 6 months.
