You are totally right, there's a problem when headphones are connected and proximity sensor changes state, I'm fixing this, also I want to say that I've been looking a way to develop a wi-fi analyzer, I just don't know which it's the correct way, using osso-wlan, wireless-tools or what.. I will develop a WiFi analizer ASAP. thanks! Edit: It's now fixed, and has been uploaded to store, I hope it will be available by mondey-tuesday
