Are you running Android 4.3 on an Xperia Z series device? If so, you’ll be glad to know that the Background Defocus camera app is now available to download. The app creates a bokeh effect, blurring the background to focus on a particular part of the image. More details on what the app does can be found in our previous post here.
The app was exclusive to the Xperia Z1s for T-Mobile in the US, however as the handset has now launched it was a matter of time before it leaked. You can install the apk from the link below, this will work on all phones (no root required). Install like you would any other third-party apk. We had no problems installing on a Xperia Z1, but we would expect it to work on all Xperia Z devices (Xperia Z1, Z Ultra, Z, ZL, ZR and Tablet Z) running the latest Android 4.3 update.
