It is worth flagging that this developer-only camera framework has a number of limitations. For example, the camera is not calibrated therefore the picture quality is not to the same standard as what you are used to seeing with the Xperia camera software. Sony also cautions that “you will experience lags and crashes.”
The experimental AOSP camera framework is available for the following devices: Xperia Z1, Z1 Compact, Z Ultra, Z2, Z2 Tablet, Z3, Z3 Compact, Z3 Tablet Compact, Z4 and Z4 Tablet. Support for the Xperia Z5 series, E3, M2 and T3 will be added in due course. If you want to find out more hit the source link below.
