Doesnt seem to work for Lenovo S650 Android 4.2.2 Installed, tried the test page, just brings up the regular "Complete action using Dialer or TelStop," no warning. Guess I'll just have to be careful.

Essential Light weight, non-intrusive, reliable. Not sure why this functionality isn't built into the OS.

SD Card I would like to put this on the SD card instead of using phone memory.
