SPECIFIC ISSUE ENCOUNTERED

On my Samsung S20+, it seems that the depthPercentage is always equal to 1.

This value should vary ? Is it normal that it is constant ?

Thanks.

https://developer.android.com/reference/android/graphics/ImageFormat#DEPTH16 1.f representing maximum confidence, in S20+ case, it seem like all 1.

Though it would be ideal if ARCore could populate those three bits with a real confidence value, the documentation does state that they are currently expected to be set to 000 in all cases. (000 -> 1.f confidence) https://developers.google.com/ar/reference/java/com/google/ar/core/Frame#acquireDepthImage()
