Pack baking soda into the 3.5mm headphone port. Smooth it even with the case. Now drip two drops of Super Glue onto the baking soda. Blow away any excess powder. Enjoy your improved Galaxy 7!
* Note: excess drops of Super Glue may cause your Galaxy 7 to burst into flames. Wear protective goggles and gloves.
