Headphone icon won't go away Ok, so I have 2 problems.  A headphone icon popped up on my Lg G3 phone yesterday.  It won't let me hear phone calls if I call or receive them.  I also won't let me play music.  The only way I can hear anything is if I plug the headphones in.  I've tried cleaning out the headphone jack, making sure the hearing aid impairment was off, and I even reset my phone.  Nothing has worked and I still have the problem.  what can I do to fix this?

Also, I had done a reset and restore that saved my contact to the SD card, but after I did the hard reset my contacts won't pop up.  How can I get my contacts back on the phone? Thanks!
I think headphone jack is shorted, and it needs to be cleaned or replaced by a new one, unfortunately both needs to disassemble the phone, here is a short video for how to replace the jack.

For the contacts, you can try to import the file from pc with a tool like Wondershare MobileGO or latest version of iTools.
