Motion Shot App which Sony embedded in the Xperia Z only is now unofficially available to all Xperia Devices running on Android 4.0+ versions.
Motion Shot which allows users to take a continuous shot of a moving object/person which will then provide a shot compiling all the frames together, as indicated perfectly in the image above.
XDA-Developers member xperiaz2 just released a modified version of the Motion Shot App that promises to work on all Xperia devices running Android 4.0 or newer. There are also people in the forum thread saying it works on other, non-Sony devices, like the Galaxy S4 or Nexus 4.
The apk is only a little over 2MB in size and you can simply download it and copy the file onto your internal storage and install the app.
