My headphone jack is damaged, only right side speaker works
i Plugged in my moto g 2 headphone jack through a home made LM 386 audio amplifier to test a speaker. It was working fine and my earphones worked when i plugged them in later. Then some voltage fluctuation caused a problem, but the speaker was still working. Later when i plugged in my earphones, only the right side was giving sound. I tested with multiple earphones and the same problem. When i tested the earphones on a different device, both sides were working, hence my conclusion that something was damaged internally in my phone's earphone jack. Please help me sort this problem out.
Is dit een goede vraag?
