Every single night, I always rely on my iPhone as my alarm as it’s closest thing I have as an alarm (most unreliable alarm). every night I make sure the ringer is on, I make sure the Bluetooth is of and the volume is up to max but to no damn avail. Does anyone else have this problem? It’s extremely frustrating as this has been happening often where the alarm doesn’t make a single noise but when I wake up I see it’s on but without sound.
