For

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

Against

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

Video is a bit of a disaster on the Sony Xperia U. Despite being technically rated as 720p capable, the sensor's simply not up to the job.

Sony Xperia U review

There's a huge amount of blockiness and digital mess on our clips, with some darker areas of the images resembling nothing more than a few rough, black squares.

In decent light when nothing's moving it does a slightly better job, but you won't really want to be recording too many of life's magic moments with the Sony Xperia U.
