Ok, so when I plug in my headset the speakers should go mute and sound should start coming out of my headphones. Only, when i plug in my phones, the speakers are still on and there is no sound from my phones. They also don't register when i try to use the radio, it keeps asking me to plug in a headset. Could this be solved via software or do i have to take back my phone? PS: they worked when i first got the phone.
