I turned on Quiet Hours from the Quick Setting tile, now I can't turn it off with the tile... I went in to Settings>Sound>Quiet hours and turned it off, but the phone doesn't vibrate anymore and the LED doesn't flash when new notification comes in...
The phone does vibrate when I turn it on (i.e. at the HTC screen) . The LED flashes red when battery is low.
Any thoughts on how to fix this? Thanks.
