I can't find the super steady mode in the camera app no matter the resolution of the video it doesn't exist. It's completely gone for some reason.
Second. There is a problem with night mode. It makes some light show up green while in reality it is yellowish. That's a huge problem in night shots. Please fix it soon.
As spyr0s has wrote above the super steady mode is only for video. About the green effect, is there a possibility that you have change some settings?? If there is, you should undo them or return the app at first settings.
Have you any tempered glass protective on the camera?
You should also try the diagnostic test for the camera trough members app. If the problem is there too, then probably has something to do with the lights or with the lens.
