I bought sony xperia z ultra last year. It’s my first biggest mobile. It’s looks very awesome. And the features are amazing as this mobile phone is waterproof. Battery is sufficient for regular use. The quality of body is valuable. Stylish looks, handling is smart. sound quality is not better as need and the another thing that flash is not available in this mobile. Camera picture quality is not as much fine and while using at night the flash is necessary but it doesnot have. But truly I love this compact mobile phone Sony Xperia Z Ultra.
