Problem with the SD2 switching between internal and external camera

Hey all,

I'm having an issue when using the camera app, and was wondering if I could please get some feedback on everyone else's experience?

I'm finding that whenever I go to use the camera app, it keeps switching between the front and rear cameras, which is quite frustrating. For example, I might be taking a video of some really nice scenery, and then all of a sudden the camera is recording me and I can't get it back. It's ruined so many good videos, and is a total pain when trying to take photos.

Has anyone else had this happen? I don't know what could be causing it. Could it possibly be that I'm using a screen protector, or could my Duo be faulty?

Is there anyway of disabling the front camera?

Any help would be greatly appreciated. Many thanks in advance.
