checked my camera and not having a baseline i cannot tell if after the update the videos are more cropped in than before, waiting for the approval of your video to have a look at it.
I know you probably already tried that but have you tried to clear camera app data? I see hard it can fix the issue but at the moment i need to look it up myself.
Could you also do a bug report via samsung members to help samsung spot the problem'
Let me know
for me if the offer is built on the one of this year as a baseline and prices do not go fairly down i will have to change brand, i love tech, i love good deals more
