Iseeu, 05 Aug 2015Does z ultra screen easily Crack?if you put it in back pocket and sit - it is likely to crack. better to buy a robust Goosebery Mercury corporation flip cover. It costs 399 in India.
Nesta, 05 Aug 2015Hello users, can i ask if the exterior is full metal and glass?thanks sides are kind of hard plastics. Back side is what material i really dont know but the dealer fixed two screen guard -one at the back and other in the front. There are some scratches at back on screen guard. This is a water proof phone. The phone cannot be opened at service center. it has to be sent to Delhi/Gurgaon where they have a Z ultra opening machine. The z ultra is kept on the machine and the machine lifts off the cover for changing any hardware. This info was given at the service center.

ashutosh , 04 Aug 2015Yup camera isn't good coz I was using lava magnum x604 before n it was having same 8mp cam but... moreThat's because z ultra has fhd display. So the images are scaled higher on the screen itself. The images will look better on a pc.
Worst phone ever seen. stopped working, got a replacement with a new handset, that too didnt work well. the most defective piece ever made by sony.
abi, 30 Jul 2015 pls pls help me .............frnds i have bought ultra z two weeks back with latest android... moreI'm facing the same problem.... But my problem is'nt major like you... Sometime my phone click anything isntantly and keep doing that then i clean my screen with a cleaning cloth.... Then it just disappear....
Camera quality is pooooooooooooor.
Sound quality is poooooooooooooor.
Performance and multitasking is best wht u can expect out of a quad-core.
I hv purchased. It for the sake of display.
