Welcome My dad bought an iPhone 6 from a friend who used it a day, it seems that the microphone and speaker after the update have stopped working. I took to check the phone and in fact the speaker and microphone do not work but only during calls. Siri, voice recorder, messeger and other applications are all OK, the volume keys work, Siri hears what is being said, when using WatsApp, everything works. Only when we talk normally do not hear anything, neither hear me nor I can not hear anyone, total silence. The first thing I did was I quickly hooked it to iTunes and I did the restore without any copy to set up the iTunes phone as new, nothing helped. On the internet, I could not find anybody to have such a problem, usually when the microphone or loudspeaker was not working anymore, but only during a conversation. Anyone have any idea what else could be done? Downgrade some? It is possible ? The phone itself visually looks OK, the original screen also has all markings. Edit I managed to insert a card from the T-mobile with which the WiFi conversation works, when talking to WiFi support everything works, it looks like it does not work only during GSM connections.
Play soft but it is very possible to damage the connection of the CPU with the audio codec and the Baseband circuit on the i2s line. The audio data during the cellular connection (GSM) goes just after the i2s line from the processor to the baseband.

Hello. Has anyone found a solution to the problem? For me it is the same, the phone has been serviced, the tape has been replaced with a microphone. Siri, voice recorder, notes - they work. The problem occurs only in conversation, I hear the interlocutor and the interlocutor does not hear me. iPhone 6 128gb
