iPhone 5 Audio problem
I have received an iPhone 5 (ios 9.2.1) that could not power on and was not able to charge the battery when is connected through lightning connector... just showed a black screen.
I removed the battery and reading with a multimeter, the battery showed 0v. I managed to revive the battery using this method https://www.youtube.com/watch?v=nxCUkHjY... after that, the red charging icon appeared and after about 2 hours the battery was fully charged.
Everything seems to be working fine except...
- When an incoming call is received I can hear the ringtone, but at the time to answer the call I can not hear anything and they can not hear me.
- When I connect headphones to listen music, the sound keeps coming out from the iPhone speaker, not from headphones.
- When I run the voice memos app, the record button is disabled and I cannot record. (voicememo screenshot)
I've reset to factory settings and also restored the ios 9.2.1 firmware via itunes but the problem persists.
Have you got any idea to solve the problem?
Is this a good question?
