You may have noticed that the camera on your Xperia XZ Premium Dual SIM doesn'tbehave according to specificationsafter the update to Android 8.0 (software build 47.1.A.3.254).
This is due to a software configuration related to the RGBC-IR and ToF sensors used by the camera. When these sensors don't work correctly, pictures taken under specific lighting/colour conditions will be affected. Results include slower auto focus and effects on colour rendition.
This has been solved in an updated software version that is scheduled for release in November, 2017.However, please note thatSoftware updates are released at different times depending on the operator, market, region or country. Therefore, I am not able to give you an exact date for when a specific update will be available for your device. In addition, network operators and specific markets may choose not to use the updates for specific models.
