Camera app freezes when trying to use rear facing camera
It's an iPhone 5. The front facing camera is ok. I can take a picture without any problems. When I tap to switch to the other camera, the camera app freezes. There's a yellow triangle in the upper left of the screen with an exclamation point in it. When I tap that it says:
"Flash is Disabled
The iPhone needs to cool down before you can use the flash."
This is what I've tried without any luck:
"Reset All Settings" (no data or media deleted)
Restored the iPhone (and upgraded to iOS 9.1)
Light pressing on the camera to try and lodge it back in (tried this even though the camera looks fine)
The power button stopped working months before this camera problem. It's an unrelated problem but it's an issue now because I can't do the trick where you hold down the home button and the power button for a few seconds to restart the iPhone.
I'm in Vietnam and there are no Apple Stores here so Genius Bar is out of the question. Please help! 😮
