Scheduled silent mode on S3 Got a Galaxy S3 with Android 4.1.2  Some time ago it started changing my phone to silent mode
automatically, every evening at 19:30. I did not install any scheduler app, nor did I change any settings. How can I find this setting and remove it?
Select System Settings, then turn off Blocking Mode (under the Device heading). You (or someone!) might have accidentally pressed that button when scrolling down the list.   You could go into it first and confirm that the 'set time' is 19:30; if not then the problem is something else.
