I've had the Telus Desire for just under a week now, and everything about the phone was working great until yesterday when the side volume buttons just stopped working. I can't adjust the ringer volume on my home screens, or the media volume when I'm running any apps, or the in call volume either. I feel like I've accidentally triggered some volume lock, but I've searched for answers and come up empty. Does anyone have any ideas as to what happened or how I can solve this? They were working just fine up until yesterday, and I don't believe I installed or changed anything since the buttons were working.
