you can plug in head phones it works unplug headphones it dont work
First, try wiping your cache partition with Recovery Mode. If that doesn’t work, it’s a hardware issue. Take it to a professional.
The speakers never work ? After restart also never sound ? Then it may be the headphone plug needs to be replaced/cleaned, because it can act as a switch from headphones to internal speaker. Also the speaker or amp could be dead.
