Sony Xperia U review

 

Sony's small Android smartphone offers a dual-core processor and plenty of charm

Solid construction ; Clear display ; Fast, smooth Android ; Clever Facebook integration ; Nice music player

Awful 720p video ; No SD card slot ; Only 4GB storage ; Browser looks dated ; Stiff camera button

The Sony Xperia U sits at the cheaper end of Sony's range of Android smartphones, using similar styling to the much larger Xperia S and the slightly larger Xperia P and Xperia Miro, setting it apart from Sony's rounder phones, including the rugged Sony...

The Xperia U is one of the best smartphones we've seen for under £200. For this price you get a capable handset providing higher performance than some more expensive rivals – all with a fantastic screen and a two-day battery life. The phone's maind...

Sony's NXT line has been taken to like Marmite thanks to the uniform look and feel across its range. Consisting of the Sony Xperia S, Xperia P and Xperia U all offer a trademark combination of bold corners, curvaceous backing and transparent banding...

Still, an update will be available in the fullness of time, and this should not detract too much from what is a generally very impressive device. It’s a solidly mid-range handset, and while we’re not enamoured with every aspect of it, the very...

The Sony Xperia U is small enough to pop in a pocket or bag, plus it

Clear, vibrant display; small but chunky; dual-core processor; cool interchangeable lip

Unimpressive battery life; stiff camera key; too small for some users
