The issue is CONFIRMED FIXED with I9505XXUBMEA firmware. I expect future updates for other regions should have this fix.
Anyone having issues with audio crackling/distortion when using headphones?
It seems with audio volume above 50% using UE600 headphones i get crackling/distortion(usually on bass) that gets worse as i increase volume. I've read other reports of similar audio issues with decent head phones but not sure what the issue is.
I tried stock, cx-270 and koss headphones but they don't display the issue.
