I am using a relatively new Razor Maxx HD and while traveling with my wife got e-mails and other alerts all during the night. I am running Android 4.1. On my old phone I was able to set up a Do Not Disturb time period where calls etc did not ring during the middle of the night. The Apple I-Phone still has this feature, does Droid 4.1 have it somewhere and I just can't find it?
