Galaxy S3 I9300 No audio during calls ( no mic,receiver,speaker and headset).Can make and receive calls.Ringer is also working.
But it works fine when using skype and fring.
reason:used skype call and left it idle and when the gsm call received, audio went off.
hard reset— not recovered
flashed Along with odin different firmwares–not recovered
flashed custom rom C9——-not recovered
updated to jelly bean 4.1.1—-not recovered
replaced headset jack——-not recovered
flashed Along with SPT box I9300XXALEF—- lost network (only circle)
repaired imei and unlocked in SPT—–S/N-00000000,not registered on network
What may be the solution.Is it hardware or software issue.
Any idea will be appreciated.
