With the official launch of the BlackBerry 10 operating system scheduled for January 31, 2013, the leaks of the devices that are set to be launched with it are continuing to pour in. After appearing a few days ago, an upcoming L-Series handset from BlackBerry has surfaced once again, and this time around, leaked images of the BlackBerry 10 smartphone had surfaced on Twitter and then it was swiftly removed.

ver the past few days, there has been a flurry of information pointing to the upcoming flagship smartphone from Samsung, currently dubbed the Galaxy S IV. A benchmark on NenaMark has just surfaced showing a handset with a model number GT-I9400. If the numbering system so far is anything to go by, this may well be the highly anticipated successor of the Galaxy S III.

The latest version of Windows Phone was launched recently, and later, a number of handsets sporting the new OS have hit the shelves. The question on the minds of those who purchased handsets before the arrival of Windows Phone 8 is when their handsets will be updated to Windows Phone 7.8. As per a report by Tonis Tech Blog, this operating system could be launched on Wednesday, thus giving users a clearer time frame for receiving the update.

     Datawind, the maker of Aakash tablet PC, has said it will clear all backlog of paid orders for the commercial version of tablet within next six weeks.

"All the paid orders (for tablets with) resistive and capacitative (screens) without SIM will be cleared in next 10 days. But the ones that want tablet with SIM they will be cleared in the next 4 to 6 weeks," DataWind CEO Suneet Singh Tuli told PTI.

The company is offering new models of Aakash, dubbed as the cheapest computer, with two kind of touchscreens -- resistive and capacitative. Capacitative touchscreens responds better than resistive touchscreens when touched by finger to operate the tablet PC.

The company has received around 40 lakh orders for its Ubislate tablet PC, which has similar specifications to the first version of Aakash tablet, he said.

The first version of tablet had processor with 366 Megahertz, 256 MB RAM and 2GB flash memory. It has WiFi based Internet connectivity option.

"Total number of paid customer was around 1 to 1.5 per cent (of the total)," Tuli said.

The company has introduced new version of Ubislate tablet with 1 Ghz processor, 512 MB RAM, 4GB flash memory and is giving option to customers to shift to this new product by paying Rs 500 extra.

The new model of Aakash runs the Google operating system Android 4.0 and has a screen measuring seven inches wide.

"It is only for those who have ordered in advance. For those who don't want to shift to other we are supplying them the same product. People who don't want to wait, we are refunding their money," he said.

Tuli said that his company is going to start production of SIM-based tablets within two weeks.

Datawind CEO said that the company is producing and shipping around 2,500 to 3,000 tablets PCs on a daily basis but receiving additional orders every day which is adding to the backlog.

He said that the company is ramping up production to 10,000 units every day.

"Right now we are doing 2,500-3,000(units) a day. We are targeting that, by end of the year, around 10,000 (units) on a daily basis. Then we will keep enhancing expanding," Tuli said.

  Over the past couple of days, a host of rumours about major brands launching handsets with a 1080p display have surfaced. The last we heard was that HTC would launch a global variant of the Droid DNA, which is currently codenamed HTC Deluxe. According to a report by Engadget, it is now the turn of Lenovo to venture into the Full HD display segment of smartphones as screenshots of the interface with a Lenovo user interface (UI) have now surfaced online.

According to the report, this handset runs on a customised Android user interface and the highlighted feature is the 1080p display it sports. As with a lot of smartphones available in China these days, the handset features dual-SIM capabilities. From the screenshot, it appears that it is connected to China Telecom's CDMA2000 network and China Mobile's 2G network simultaneously.

Engadget's source informs it that the display measures between 4.5 inches and 5.5 inches. As of now, this is all that is known about the handset, and there is not even a name to go by.

As mentioned earlier, HTC could also be preparing a global version of the Droid DNA, a handset that is designed for Verizon in the US. This handset features a large 5-inch 1080p display and since it is the global version of the Verizon Droid DNA, the specifications should be very similar. The Verizon model comes equipped with a 1.5GHz quad-core Snapdragon S4 Pro processor and features 2GB of RAM. As far as connectivity is concerned, this handset comes equipped with LTE and NFC capabilities. However, we have to wait and see if the global variant features the same specifications or if HTC launches it with slight modifications.

There is no official word yet on when this handset will be released, but one can expect it to be introduced at the Mobile World Congress event held in Barcelona next year.

In related news about 1080p displays, a Korean website, Asiae, reports that Samsung is preparing to introduce a 4.99-inch Full HD Super AMOLED displays with a resolution of 1080p at the Consumer Electronics Show (CES) 2013 event early next year.

The handset will in all likelihood be mass produced in the first quarter of 2013. It will be used in Samsung’s upcoming flagship smartphone, the Samsung Galaxy S IV, expected to make its debut at the Mobile World Congress event scheduled to be held in Barcelona early next year.

Commenting on the display, an official at Samsung Display said, “It has more than 100 pixels per inch more than the Apple iPhone’s 326 ppi stretched beyond the limits of the human eye level.”

The Samsung Galaxy S IV is touted to be Samsung's next flagship smartphone after the Galaxy S III. The latest rumour about the handset comes via SamMobile, which sourced the information from DDaily that the Galaxy S IV will feature the new Samsung Exynos 5450 processor. The S IV is expected to feature a lot of improvements over the S III, the most notable being the increase in the size of the display. The anonymous Samsung source has stated that the display size will be 5 inches, and that it is not certain if the screen will feature flexible display technology.

It appears that this niche space is slowly but surely getting populated with high end displays.
