So I recently bought my Galaxy SIII, and I noticed that when I plugged it into my phone, the sound was fine but none of the control buttons actually worked...I didn't pay much attention to it because I just assumed that this was the case (nothing is perfect)....But then my brother gave his SIII earphones to my mom who has an SII and the buttons worked fine, she could answer phone calls, start music, and increase the volume. I tried messing around with my earphones (and I tried using my brother's) but nothing I do makes the earphone controls work on my phone, and I made sure they were properly plugged in in each attempt (I heard the click). I'm not sure if it's because of an app or something...Any help would be greatly appreciated!
