Why the NotchStar mirror preview is flipped
The NotchStar mirror preview is flipped on purpose, so it behaves like the mirror you use at home. Move your hand left and the hand in the preview moves left. NotchStar has no setting to turn this off.
What the flip changes
It changes only the preview in the notch. NotchStar does not touch your camera feed, your call app or the video other people receive. How your call app shows you to others is decided inside that app.
Why you might see text backwards
If you hold up a book or a name badge, the words look reversed in the preview. That is normal for any mirror. To read how it looks to others, check the self view setting inside your call app, or look at a test recording made there.
If you want an unflipped preview
The mirror cannot do this. The camera light, framing and lighting checks work the same either way. For an unflipped view, use the preview inside your call app, or a camera app that offers that option.
