Sony Xperia J

Aug 29, 2012
Market status


  • Small dimensions (4.89 x 2.41 x 0.36 inches)


  • Low pixel density screen (245 ppi)
  • Single-core processor
  • Too little RAM memory (512 MB RAM)
  • Low-resolution camera (5 megapixels)
  • Low-resolution video capture
  • Lacks an ambient light sensor for automatic screen brightness adjustment




Sony Xperia J, the latest affordable addition to the Xperia lineup sports a 4" screen with decent for the size 480x854 pixels of resolution, a humble 1GHz Snapdragon processor and has 512MB of RAM plus a 5MP camera on the back that records VGA video -all specs that are ensuring its entry level status. Internal memory is 4GB, but thankfully we have a microSD card slot to expand that with up to 32GB more. The showstopper here is the battery - it is not every day that we see a 1750mAh in a 4" affordable device, and Sony is quoting the excellent 8 hours and 30 minutes of video playback with it. The curvy, easy to handle 9mm thin chassis of the Xperia J is arriving in white, pink, black and gold colors, to suit every taste.

  • Technology:

    Technology - There are two main screen technologies currently used in phones and tablets: LCD and AMOLED. The former usually features a light source and liquid crystals, while the latter is based on organic light-emitting diodes. Newer LCD variations like IPS-LCD and Super-LCD allow for very accurate color reproduction and very wide viewing angles, where no significant image quality loss is observed. Current AMOLED screens differ in such a way that they can exhibit much more saturated colors (sometimes too much) and incredibly high contrast levels, which is due to black color being completely black in AMOLED displays.
