[Q] Loud Speaker Detection Android App
I want to know is their any app on Google Play that helps you to detect that other other turned on loud speaker while calling ?
Can any one give me an idea, if we program app like this, how do we detect that other person turned on loud speaker ?
Do we match audio frequency ? Detect Noise ? or any other idea that work good.
