Design, Build Quality
The Xperia Z Ultra looks like a bigger version of the Xperia Z in terms of design and build quality. The Xperia Z Ultra is water and dust resistant just like the Xperia Z. The Xperia Z Ultra is one of the biggest phones out there, but it is also the slimmest device with a Full HD 1080p display.
In terms of dimensions, the Xperia Z Ultra is way bigger than the Xperia Z. The Z Ultra is 4 centimeter taller and 2centimeter wider than the Xperia Z, but is 1.5mm thinner. In terms of weight, the Xperia Z Ultra is heavier at 212g while the Z weighs around 146g.
On the front of the phones, we have the display above which we have the earpiece and front camera along with ambient and proximity sensors on both the phones. The earpiece is along the top edge on both the phones. The front camera is at the left side of the earpiece in both the phones.
Both the displays have relatively thick bezels and there are no navigation capacitive keys and hence all the navigation is restricted to on-screen buttons which eats away valuable screen space. The mouthpiece is along the bottom edge.
The design language is similar in both the phones although the Z Ultra has a more mature design with nicely curved edges instead of the flat edges on the Xperia Z.The position of keys is similar with both the power lock key and the volume rocker on the right side of the device. On the Xperia Z Ultra, we have the covered microSD card slot and microSIM card slot on the right side too. There is a uncovered 3.5mm audio jack at the top of the right side on the Z Ultra. While on the Xperia Z, we have just the covered microSIM card slot in addition to the Power lock key and volume rocker and the loud speaker on the bottom end. The volume rocker on the Xperia Z Ultra feels much more comfortable and offers better feedback than the slim one on the Xperia Z.
On the bottom, we have the loud speaker on the Xperia Z Ultra while there is nothing on the Xperia Z.
On the left side, there is the covered microUSB port on both the phones at the top end and the dock connector towards the center.
On the Xperia Z, we have the covered microSD card slot between the two. On the top, we have the secondary microphone on the Xperia Z Ultra while we have the covered 3.5mm audio jack in the Xperia Z.
The back of both the phones is pretty similar with just the camera and the same glossy glass back. Both the phones are fingerprint magnets. The camera on the Xperia Z Ultra is along while the Xperia Z’s 13MP camera comes with a LED flash and secondary microphone. There is NFC on both the phones at the back. Both the phones have non user-replacable battery and the back cover is not removable.
