It's electromagnetic radiation from your phone. When you're about to be called, it will pick up the call request from the cell station and answer the request. The EM radiation from the phone induces a current in nearby cables, which is transformed to sonic waves by the speakers.
- dsc 16y agoHmm I'm kinda concerned that someone might be spying on me :) But yes, I saw both your comments and "sometimes it does it for no reason" is still scary to me.
- coryl 16y agoCould be your phone being pinged in order to keep tabs on your location. I would throw the phone away and change your identity. You must have upset someone in the government. That or its nothing at all.
- anigbrowl 16y agoIt's just pinging the nearest base station in response to a periodic poll of which devices are in the cell, like a 'stay alive' ping on a temporarily dormant FTP session. You can probably limit how diligently the phone keeps in touch with the network but will have more missed/dropped calls as a result.
- _0ffh 16y agoWell, the only way to make 100% sure you're not spied on with your mobile phone is to turn it off AND remove the battery. I recommend this method for the paranoid moments in your life! ;-)
