After the most recent update to the Motorola Camera app, my ability to switch between the front and rear camera on my Verizon Moto X has disappeared. The icon disappeared. If I clear cache the icon returns, but as soon as you press it, it disappears again and takes a picture? I have wiped the cache partition, uninstalled and re-installed the software several times to no avail. I have read on forums and the app reviews of others experiencing the same thing. Anyone have an answer to solve this problem?
