An electronic device automatically reverses a left-right orientation of content displayed by the device when detecting that a user is viewing content of the device via a mirror. Some embodiments reverse the content upon detecting a trigger such as a reflection of an image displayed by the device, indicating that the device is displaying content against a mirror. In some embodiments, the device reverses the content upon detecting that blinking markers displayed by the device are inverted or upon detecting a blinking marker flashing in a particular pattern consistent to that emitted by the device. Some embodiments reverse the content upon detecting both the reflection of the image and a reflection of the user. Further, some embodiments reverse the content upon determining that the user is facing a mirror and switches back to its normal orientation when the user is viewing the content by directly looking at the device.
