It seems that every iPhone launch has to be plagued by problems. The iPhone 4 had the antennagate, the iPhone 4S had battery issues as well as Siri outages. Now it seems a number of iPhone 4S users are facing an audio issue where they can not hear the person on the other end of the phone.
Picked up a Verizon iPhone 4S – 32GB and on about 1 in 10 calls I get no outbound audio when dialing. Call shows the timer counting as if the call is progressing but absolutely no ring back and cannot hear the party on the other end when they answer.
Another user on AT&T chimes in:
I am having the same issue with an AT&T 32G 4s, hitting the speaker button only works sometimes. It also has happened to me when using the Apple provided headphones/microphone.
The problem is intermittent as the comments say. Certain users in UK and Australia are also affected by the issue.
Whether the problem is a hardware issue, or a software bug is yet to be known. The newly released iOS 5.0.1 beta doesn’t seem to solve the problem. Some users suggest that the problem is related to Bluetooth headsets, while others could reproduce the bug without even switching on Bluetooth.
As Mashable points out, a Facebook group named “iPhone 4S Outgoing Call No Audio” has also been created, suggesting the scale of the bug. Interestingly, another problem related to audio echo plagues a subset of iPhone 4S users.
Apple has so far remained silent on the issue. If the problem is indeed a software issue, we expect Apple to resolve it when it releases iOS 5.0.1 to public.
Have you experienced any such issue on your iPhone 4S?
