Sony Mobile now rolls out build number 47.1.A.5.51 to include the fix for its camera sensor problem which results in the ToF(Laser AF) & RGBC-IR sensors to work. The update also brings the latest November batch of Android Security updates across several regions globally.
Last week Sony rolled out the latest Android Oreo update for their flagship Xperia XZ Premium, however, unfortunately, the update still have few issues related to RGBC-IR and ToF sensors aren't working properly after the update. The good thing has Sony acknowledged the issue related to cameras and confirmed that patch is on its way.
The camera issues are for the dual-SIM variant of Xperia XZ Premium which is running on the 47.1.A.3.254 build number of Android Oreo. The company stated the issue is due to RGBC-IR and ToF sensors configuration of latest Android Oreo update. This results into average picture quality and also affected the color saturation. The autofocus shutter speed is also affected by the update. According to Sony, the upcoming software patch will resolve this issue and this patch will be rolled out in this month. Unfortunately, the company didn't confirm the exact schedule of the update because different regions will get the update at the different time. It is also in the dark whether this update will bring improvements to the camera or not.
