iPhone XS and iPhone XS Max were welcomed with a truck full of complaints by the users regarding issues with self-portraits. According to the users, pictures appeared like a poorly edited photograph or photoshopped which added unreal colors which made picture totally unnatural.
Apple provided a solution to the problem in iOS 12.1, by removing the bug in HDR smart camera system beautygate. Earlier this smart feature HDR function was selecting the wrong frame base for HDR processing while taking selfies. In Spite of selecting the frame that would use short shutter speed to maintain as much detail as possible, the function used to select frames takes the longer shutter speed with blurred pictures.
The issue got worse when the complaints stated that the front camera lacked stabilization which was causing blurred pictures than the sensors which used technology. Currently, Apple is with its fifth developer beta for iOS 12.1 which has no fixed date but it is likely to be within the next week.
