iPhone 4s - Cannot Change Volume
Hello,
I've been an iPhone owner for a couple of years now and haven't run into this issue before. I hope it's an easy fix. The problem is that I cannot change the volume to hear things like the keyboard clicks, or videos that I've shot with the camera. Under settings -> sounds, I don't see anything usual. We have 2 iPhone 4s' in the house and they have the same identical settings.
The volume buttons don't do anything, as pressing the up or down buttons show the ringer pop-up, but the bar on the bottom that shows the volume does not display. I try to press both buttons at different times to no avail.
I tried turning it off and on by holding down the button on top. Didn't fix it. I also tried holding the top and home buttons. That didn't fix it either. So before I connect it to iTunes, do a backup, and a restore, am I missing something?
I can hold down home and Siri makes the usual sounds and she speaks back to me, but the rest of the OS isn't making any sounds. Please advise...
Thanks in advance!!
