Answer to: How can I repair the headphone jack?Sgreend: Headset (not Headest) Blocker doesn't work on Android ICS or higher versions, including Jelly Bean. See https://github.com/dlew/android-headset-blocker. Google Play won't even install it. This solutions regarding sticking in a piece of plastic must not apply to Droid Bionic after March 2012, when I bought mine. There is no gap between the headset jack and case. I have cleaned out the jack with a Q-tip stick & alcohol. It helped, but isn't 100%.
