As far as power is concerned, then now we have a device which actually possesses a better processor than the Samsung Galaxy S4 (which was the most powerful beast till now). The processor used in the new Sony Xperia Z Ultra is the Qualcomm Snapdragon 800 which is a quad core processor and clocked at the frequency of 2.2 GHz. As far as performance is concerned then I am damn sure that this new device will give a touch fight to the Samsung Galaxy S4 but this device is yet to reach the other parts of the world and as of now it has only been released in China.
I am little bit appointed with the screen size which is 6.4 Inches. I know that most of the users like big screen but I personally feel that 5 Inches is big enough which captures the whole area of the palm and does not leave much space to be handled single handedly. Now the Samsung Galaxy Mega 6.3 was the latest smartphone with the largest screen launched by Samsung and this device goes ahead by 6.4 Inches. Though, I cannot compare these 2 devices as Sony Xperia Z Ultra is obviously better in all the cases when compared with the Samsung Galaxy Mega 6.3.
The display is Full HD providing you with the best clarity on this display size. The primary camera used on this device is 8MP and that of secondary camera is 2MP. The primary camera is also equipped with the feature of HD video recording at the rate of 30fps and other common features like face-detection, smile-detection and other are available on this device.
The internal memory of 16GB is available and that too with the external memory card slot which can help you to extend the memory. The Operating System on which this smartphone operates is 4.2 Android Jelly Bean and along with it they have also added the feature of water-resistant and dust-resistant. This is the slimmest phone with such a huge screen size in the world available as of now with the thickness of 6.5mm.
If they would have gone for the screen size of 5 Inches or 5.5 Inches then it would have been a great competitor of Samsung Galaxy S4 and the sales ratio of this device would have been higher because looking at the current scenario Samsung Galaxy S4 clearly leaves its contender behind in terms of power and performance. Stay Tuned to be reminded whenever this products launched into the Indian market.
