A common problem that iPhone owners have is when their iPhone ear speaker does not work properly, or when the iPhone has low volume during calls. This can be really annoying, especially when you take important calls quite often.
iPhone ear speaker not working? – Fixed earphone here!
The most common cause of low volume during a call on your iPhone is fluff and dirt particles that get clogged in the speaker grille of the earpiece.
That being said, you need to clean it up appropriately to get your iPhone volume back to normal. You can do this by using an anti-static brush and lightly brushing the earpiece to remove lint.
If your audio is routed elsewhere, it may mean that you won't hear anything coming out of the ear speaker when you're on a call. The sound can be diverted through your headphones or through a speaker, you have to make sure of this.
