Nexus 5 beeps everytime it's shaken

[Ecchi83]

If it's in my pocket, it beeps every other step, even when it's sleeping. It's not the nfc setting and I can't find any other threads on this. Any ideas?

Welcome to the forums.
I have scoured my N5 too and I can't find anything. But I am also on a custom ROM. I can ask around.
