Ok so i had my headphones that i used and they worked fine, until once they started to sound very bad and i noticed that when i move cable near jack i can it to work good for a few seconds. So i try them on my pc and they work fine no problems at all, then i took different headphones and they worked for day or two and same thing happened again... Sometimes my phone doesnt detect headphones at all. So i want to ask you guys if there is fix for that or i need to replace my headphone jack if that is possible. I tried cleaning it with qtips but it didnt help.
