Camera Error on Moto G

Problem

You open the Camera app on Moto G to take a photo. The app throws a Camera Error message and closes. If the Moto G is restarted, then the Camera app works fine. But after some hours, this error might happen again.

Solution

According to the discussion on this forum thread, the culprit is the Skype app. It seems to be not releasing the camera resource in a clean manner.

I used to face this error on a daily basis. Skype seems to be have fixed their error. After their recent update, I have not faced this error in more than 2 weeks. For reference, the current Skype version on my Moto G is 4.7.0.43514.

Tried with: Android 4.4.2 and Moto G
