I have a Gmail account for Android ROM testing purpose. And I kept receiving this annoying email from Google anytime I use that account to sign in Gmail (most of the time it's a clean flashed Android phone which I will wipe out later). Here is how to disable the email notification.

In developing PhoneLab Conductor app, I need to provide user a way to give us feedback after applying OTA update. Although this feature was disabled in release, I thought it's worthwhile to record how to implement that functionality anyway.
