My volume adjuster disappeared. How do I get it back?
Today I tried listening to music on my iPhone 4S, only to find that my volume adjuster had disappeared. And just to clarify, when I say that it disappeared, I mean that when I press the volume buttons on my phone, I see the speaker icon but the gauge bar is gone. I tried to test if this issue was only happening in one place, by checking out if I could adjust my volume through my YouTube app. Unforuntately, the volume slider has disappeared from the app as well.
I tested my alarms, etc. and the problem is not my speakers -- my phone is still fully functional in this regard.
I can't figure out what I did to cause this change, but I would love any advice you have on how to fix my phone. If it makes any difference, I have already tried restarting it several times.
Thank you in advance for all of your help and advice. 🙂
iPhone 4S, iOS 5
