Line in half broken!?

Hi,
I recently got a problem with the line in of my meizu, since yesterday the sound is totally distorted unless I only plug in half of the connector into the line in (but that's too unstable when you are moving). Is there any way of fixing that? I already reset all the settings and formatted the meizu, but neither works so it's most likely a hardware issue.

First off, its a line out since it isn't an audio input, its an audio output. Have you tried another set of headphones? If you haven't, try that. You could have a bad set of headphones. Most issues with the line out has more to do with the headphones than the actual line out.

sorry 'bout that mistake, anyway no i havent tried that but the headphones still work totally fine on my laptop.
