Some data at http://www.technical-direct.com/en/smartphone-user-experience-analysis-audio-ii/

If you can keep the signal below 100 mV range, it should be safe for mic input (not damaged), although can be heavily distorted.

I think the optimum would be to main to 1-10 mV input signal level.

What are the audio levels required for the microphone input?
The audio level out of the thing I want to use is in the range of 1 watt into an 8 ohm load. How sensitive is the microphone input of the android device? Don’t want to trash the microphone input to the phone.
