iPhone 5S earpiece, Microphone & headphone jack not working

"Restore / Update iPhone via iTunes?

Looks like nobody here has said they have tried that yet. If it goes bad right after a software update do NOT replace any parts inside the phone because it is caused by software and not hardware."

"iPhone 5s I have same problem,
