Mirrored Selfies on Older iPhones
With iOS 14, Apple added the option for users to take mirror-image selfies, but for whatever reason, this was limited to recent iPhone models — the 2018 iPhone XS/XR and later.
iOS 14.3 adds this to the rest of the iPhone models that support iOS 14, going back to the iPhone 6s and original iPhone SE. While this doesn’t change the default behaviour — selfie previews will still be shown mirrored on the screen, but actually captured in a normal orientation — users who prefer to get an exact copy of what they see in the preview can now toggle on the alternate behaviour in the Camera app settings.
