Definitely works properly for me and has throughout the betas. Mute switch toggled on side of phone and alarm plays at full volume. You sure your alarm volume was turned up? Maybe you were connected to a Bluetooth device and the sound was trying to play through that?
[doublepost=1505769191][/doublepost]Just had my 7 become completely unresponsive to all input except gestures. Could not tap on anything and even holding the power button would not evoke the power down screen. Strangely, I could slide up for control center and down for Notification Center. Hard reset was required.
Very strange. I’ve just hard rebooted my phone and now it works again as usually. Thanks though
