Sony Xperia Z Ultra: A Hands on Review

Sony has come up with yet another version of its flagship phone, the Xperia Z Ultra.  We have seen Sony Xperia Tablet Z: Tablet version of Xperia Z. Its a phablet sized Xperia Z. Here is our detailed review on the phone.


At 6.4 inch, the Xperia Z Ultra can’t really be sorted in a smartphone or a tablet anyways. Or it may have redefined the phablet category. With this device Sony has joined the phablet bandwagon.

It follows the same Omnibalance design ( Remember Xperia Z!!) with its sharp and angular corners and boxy design. Like the Xperia Z, it is completely covered by glass which gives it a premium feel. As you can see, it is substantially larger than the Xperia Z and Xperia  ZL. With the dimensions measuring 179.4 x 92.2 x 6.5 mm, it is the largest phone out there in the market. but it is also the thinnest ( Thats right!! Thinner than Xperia Z!!).

Continuing the water resistant trend, the Xperia Z Ultra also is IP56 certified i.e. dust and waterproof. According to official sources, it is water resistant up to 1 meter for 30 mins. To add to the styling, it has aluminium bands around the sides.

The round metal power button design continues in this phone too.


The Xperia Z Ultra has a non-removable 3050mAh Li-Ion battery which we believe would give the phone enough juice to last a day. It comes with a 16GB of internal memory with the possibility of expansion up to 64GB  using micro-sd cards. The phone is a beast underneath. Powering the phone is a Qualcomm Snapdragon 800 chipset running at 2.2GHz (Quad Core). It is supported by a 2 GB of Ram. The graphical tasks is handled by Adreno 330 GPU. So, throw any app at it and the phone will work it out without a flinch!

All the above culminates into a device weighing 212g, which is quite heavy. So, users who very picky about the weight of the device should stay away.


The 1080p 6.3 inch display is the first thing anyone would notice in this phone. The Display is HUGE!! Movies and games on the phone would be superb. But the main selling point of the device is the all new Triluminous panel Sony has implemented in the device. The Xperia Z/ZL, Xperia ZR drew a lot of flak for having a LCD panel which resulted in very poor viewing angles and disappointing contrast. So, Sony has come up with a new panel which according to latter will give the very successful AMOLED panel from Samsung a stiff competition. So, does it live up to its expectation. We find out!

First, what is Triluminous? Simply put, Triluminos is a technology that enables LCD TFT displays to show a wider range of colors, and thus to display images that are richer and more vivid. It uses quantum dots to show color gamut that is 50% larger than conventional LCD displays. You can find out about Triluminous tech here.

Triluminous Display

In our review, we found out that the display was indeed colorful and vibrant just like any amoled panel. So, if you like watching movies and playing games on your device, you would love this phone. But the near infinite contrast which the amoleds have is not shared by this panel. We also found out that the colors washed out just a little bit on viewing the phone from extreme angles.

Overall the display is crisp at 344ppi and vibrant. So, a major improvement from the conventional LCD panels Sony used in its previous devices.



The Xperia Z Ultra boasts a 8mp shooter which is lower than the 13mp we saw in the flagship phone. But in our tests, the phone gave good quality pictures. Now here’s the shocker. There is no flash on the device!! I mean if we are paying a premium for a device, one would expect a minor addtion like LED flash. But there is none. I don’t know why Sony didn’t think of including it but it sure gonna lose some major points for it.

Other than that, the camera performs just fine.


The device comes pre loaded with the android jellybean 4.2.2. It has the usual Sony UI on top of the vanilla android. All the features like Walkman, Stamina mode etc make a return.

Pencil Works!!

The one different thing I noticed was that there was no lag on the interface. The same UI lagged a lot in the Xperia Z when it came out. Is it because of the absurdly powerful device or if Sony has optimized it remains to be seen. Another new feature is the ability to write in your own handwriting. Sony has taken advantage of the screen estate available. Another neat feature is that, you can write on the device using a pencil. The screen is made in such a way that it doesn’t smudge against the pencil.


The phablet is very powerful, looks stunning and is sure to raise eyebrows. But I think the phone of this size would appeal to very few people. If you are looking for a device with a large display and can make calls, look no further. The Xperia Z Ultra is a fabulous device which will satisfy all your nerdy needs.

Colour Variants

The Xperia Z Ultra is available in black, white, and purple color variants. It is available at Flipkart for Rs. 44690.
