Iphone 5c: No keyboard sounds, lock, or camera sounds

I noticed yesterday. I don't know why this is happening. I check the settings and I have all the volume at max. Is it becauase I recently updated my phone?

You probably have it on mute, go to settings and look under general, there should be a thing about side switch, if it already controls mute then you should see a switch on the side of the iPhone, then flip that switch and it should work, if it says something else, change it to mute then repeat the previous step.

Look on the left side of your phone because you probably moved the switch. You need to move that switch thing upward. I had that same issue.

Look on the left of your phone at the first button if there's a bit of white showing you have put your phone on mute so just slide that button the to right and it should fix it.
