Background and Identification ¶
The Sony Xperia Z Ultra is known as a phablet (phone/tablet) and stands at 6.44-inches tall. The phone is exceptionally thin at 6.5mm and does not include a stylus. It was released on July 24, 2013 at a price of $679.99. It features a full HD 1080p display using Sony's Triluminos and powered by X Reality. The phone comes with Sony's applications as well as several preloaded Google apps.
The phablet features a nice 1080p display, is slim and sleek in design, has super-fast processing prowess (when managing a single function at a time) and best of all, the phablet is water proof, shatterproof, and crack resistant.
The Xperia Z Ultra might be too big and clunky to function as a phone. The camera is lacking in functionality in comparison to other phablets, (in regards to not featuring a flash function for the camera) and it lacks multitasking capabilities. The phone also tends to freeze up.
Sleep of Death ¶
Sony has released an Over the Air (OVA) update that solved this issue. However, a hard reset may also be required.
