Sony launches giant waterproof Xperia Z Ultra phone
The Xperia Z Ultra is 6.5mm (0.26in) thick - only slightly deeper than the thinnest device on the market, Huawei's Ascend P6.

Unlike the original Xperia Z the new phone does not need a flap over its headphone socket to protect it from water damage, addressing complaints the feature was fiddly to use.
It can also be submerged to a deeper limit - 1.5m (4.9ft) in freshwater for up to half an hour.
The device also features:
- A 1080p resolution screen with in-built software to upgrade lower definition videos and photos
- 16 gigabytes of internal storage with support for 64GB microSD cards
- An 8 megapixel rear camera
- A battery offering up to 11 hours talk time or 120 hours of audio playback - a figure which Sony claims is a record
Those concerned about using such a big device for quick tasks are also offered an optional bluetooth add-on which can be paired to the handset using NFC (near field communication) to make calls, view text messages or stream music.
