Just picked up a Galaxy Nexus (my first Android...not counting the unfortunate accident I had with a Note 2 last week) and have set it up with Jellybean 4.1.2 Yakju. (I've also installed the 4.2 apk for the new clock, in case that matters.) Problem: I'm using two email client apps. EMAIL for my work (Exchange) account, and GMAIL for my personal Gmail account. I went into each app and set it so that notification sounds are set to silent, and no vibrate. When I receive an email from Gmail, it shows up in the notification bar without making a sound. That's just how I want it. When I receive an email from my work account, it shows up in the notification bar but it also sounds an alert. Not what I want; I want it to be silent! Interesting notes: 1) If I completely turn off notification for EMAIL, then when I receive an email, it will not show anything in the notification bar...but the alert sound will still occur! 2) If I change the EMAIL notification from silent to some other ringtone, when I receive an email, I will hear that newly selected ringtone...AND then I'll also hear the same ringtone that it has been making all along. This is driving me crazy, because a few hours after midnight, the server from work emails me logs from a variety of processes which results in a series of alerts, meaning that I can't leave the phone by my bed. Can anyone help me out? If I can't figure out the root cause, I'll have to try to mask it by installing some kind of Tasker-type app that disables EMAIL syncing overnight. Thanks in advance for any responses.
