When I use the camera App, both the front and rear cameras work as expected with upright images. However, when I run Skype and go into settings and enable Test Video, the front camera shows an inverted image, but the rear camera continues to work as expected with an upright image. A left/right swap would not be too bad, but inversion is definitely ridiculously bad.

Update: Correction: "if the I will appear upside down on my contacts screen" should have said "if I will appear upside down on my contact's screen". Thanks, Jake P, for spotting this error.
