Bug description

If you take a picture is "orientation" is incorrect - it is flipped, so left becomes right, and visa-versa.

However, if you make a video call, or file, it is correct.

Steps to reproduce

• Take a picture
• Take a video
• Compare the "orientation"

Actual result:

• Flipped image

Expected result:

• Pictures is the same orientation as taking a video

Device info

Device: Samsung S9
Android version: 10
Signal version: 7.5.2

It seems to depend on the orientation of the phone... Horizontal, vertical and so on

So this seems to be particularly for selfie pictures. (Pictures taken with the back camera are always correct)

When Signal takes a selfie picture, both the preview and the final image are mirrored left-to-right (meaning that text in the image is unreadable).

However, when Signal takes a selfie video, the preview is mirrored left-to-right, but the resulting video is not mirrored.

	Preview	Resulting file
Photo	Mirrored	Mirrored
Video	Mirrored	Not Mirrored

These are the same results as I get for my default camera app on a Zenfone 9.
