Hi All, been coming here a long time, but first post. Hoping you fine folks can help me out a bit. I've searched a ton on the web, and this board and cannot find the answer. My wife's Nexus has just started playing a chimy sound on unlock. She does not remember turning this on, and my Nexus does not play it. We've both gone through settings/sound/unlock/etc. several times, however we can't find this setting. I'm probably dumb, so I apologize if this has been directly answered, or is a simple fix i'm not seeing. Thanks in advance!
