Hope you can help me to understand why the device makes this sound shutout any specific reason .I'm surd there is one but I really can't find out. I already uninstalled a lots of app but no results ...
I recorded it
When I was facing the problem on my Nexus 4, after a lot of research i found out that the transit card was creating the problem.
Every time the card came close to the rear of the phone it happened as the phone tries to communicate with the card via NFC. Turning the NFC function off solved the problem. Obviously any other card/device that works with a proximity sensor (like an access card at work) would have a similar effect. Hope it helps.
