Hi guys i need your help because i'm a super noob,
I'm new to the samsung/android world. I've been an apple fan boy and decided to switch.
I bought a samsung galxy s4 i9505 it was on 3 UK. The phone works fine but after a few calls, I can't hear the other person and they can't hear me. When I restart the phone it works fine again and then after a while it does it again. I updated the phone and also restored it to factory settings. Do you have any idea what could be causing the problem? I will be forever grateful if you guys can help me!
Thank you all in advance.
