Why doesn't my phone work with both ear and headphones?

[AC Question]

Hi. My phone doesn't work with both ear and headphones

I was listening to songs on my samsung galaxy core prime, then my earphones came off. When i put it back, my phone didn't notify that the earphones were in it. The songs started playing through the speaker

Welcome.

That will probably need a hardware repair.
