no sound only during calls
the iPhone 5 has taken some heavy damage but it's still working fine, but when i make a call there is no sound. i can't hear the other side and the other side can't hear me, not even a dialling tone. i checked the earpice and the microphone with the voice memos app and it works fine, there is also good reception and i can surf the web and use other apps like Skype and whatsapp.
i did a little digging on the internet and some say the problem is the baseband chip U501_RF, is that true and if so how can IFIXIT?
