NFC Mute

This is a very simple app that does only one thing:

- Toggle your device between volume and silent or volume and vibrate, depending on availability of the vibrate feature, when a particular NFC Tag is read.

Other NFC settings management apps will do the same, but they would require a separate NFC tag for devices with different capabilities. NFC Mute can use the same tag.

I used this app for a situation where I was coming in to work carrying multiple devices, each of which had to be put on silent or vibrate. Rather than toggle each device by interacting with the screen, I simply passed each device over the NFC enabled sticker placed at my desk.

Note: On Android 5 devices, the silent mode is now Priority mode, which can be configured by system settings.

It also encodes the tags for you. (I know, I said it only does one thing)
