I have seen a few threads on this topic and read through a lot of them. I created this new discussion board because some of those boards have been falsely marked as "solved". The problem (which, from what I can tell, has been a problem since the new updates in April) is that when the front facing camera is set on single person selfie mode it will take a picture and then the actual photo will be zoomed in (otherwise known as CROPPED on every side) for an unknown reason. Camera settings all on default, never been changed. No face correction filters are on. Save photo as previewed is on. There is literally no setting or reason this should be happening. Other threads have suggested "the solution" to be switching from single person selfie mode to group selfie mode which widens the angle of the shot, but will actually not crop the photo you take. Fine solution if you don't care about your phone not working properly which I find offensive that Samsung actually marked that as a solution. I want answers. I want updates. I want a properly working phone.
And here is some more info for the techies since I saw it requested on another discussion thread:
Model number: SM-G960U
Software version: G960USQS4CSC8
Samsung provides updated data files to the carriers, but the carriers actually push them to their phones, and on no particular schedule. They all take time to update their own additional software (i.e., bloatware) to be compatible with the new update and perform testing. It does sound like Sprint is still on an older version. Try searching manually for software updates every few days. Hopefully you'll get the June patch soon.
