Silent mode turns off by itself
I have a problem with my D802 (16gb) after the most recent update (Baltics 20F). When i set the phone to "Vibrate" in the evening it turns it back to "Sound" by the morning (I suspect it happens at midnight when the date changes). Also the problem can be reproduced when putting the phone into "Vibrate" and then unchecking "Automatic date and time" from the settings - the phone switches to "Sound" profile. The same happens when manually changing the time. Phone is stock, non rooted.
Does anybody else with 20F have this problem?
