Recently i notice my s3 have been playing on only one side when attached to a speaker. My dad helped to send it for warranty and i called them again to explain whats the problem throughly. all i get was your phone is still under service and two days later they send it back, reformatted but i dont think they did anything with the earjack. pissed me off and time wasting, thinking of bringing my whole speaker to the service center and try it out in front of them.

Before this, there wasn't any problem with the earjack. same speaker same phone.
