Hi, my name is***** will assist you.
First try and clean the headphone jack, out the headphone jack in and out a few times and blow the port out with air. If that does not work then the best option will be to try a reset to see if this is a software or hardware issue.make sure your data already backup properly, because doing the factory reset will erase all of your important data. Do it carefully.
In some condition, we can access the setting menu of Samsung Galaxy Note, than this format can be done using recommended way:
Menu > Setting > Privacy > Factory Data Reset > Reset Phone
When we choose Reset Phone, the warning will be appear and make sure you understand that all data will be erase or deleted. The data you have to backup before is : Contact / SMS / downloaded Application and others.
#Option 2: Hard Reset Samsung Galaxy S3 with Hardware Key
