Why doesn't my phone ring after I have it on silent?

[AC Question]

my phone doesn't ring after I have it on silent

When I use the volume control to lower the ringer, once I turn it back up to full volume, it doesn't ring when a call is coming in.

I think could happen mechanical damage. If it is very unlikely to do.
