When it was firstly announced, iPhone 4s came with "a million" of goodies within and offered for all the iOS device lovers around the world, however "a million" bugs are tailing this A5-based phone too. For example, the disappointing life battery performance, which so far has not been solved yet, and iPhone 4s audio echo bug. But worry not I won't go into detail on this.
Aside of those bugs, another bug discovered and the iPhone users have filed their dissatisfaction on Apple support forums due to one problem: which is they are not being able to hear anything while making phone calls.
And so far, this issue found on the three major carries and not always happens in every call (Thank God). The reported situations say that the outgoing callers can't hear anything via their earpiece while calling. Not just that, another users also complaint a worse condition to which their outgoing calls are muted in their earpiece, however the the one they call can hear the muted caller on their phone.
The culprit of the problem is likely the driver issue between iOS software and the A5 hardware. Anyway the issue only does not appear on the incoming calls.
This is another must-be fixed homework for Apple to keep their customers in the satisfaction stage. And fortunately there is a workaround to the said problem, albeit it is not a fix, but I hope it will work for you. This what you should do:
Workarounds for iPhone 4s muting outgoing calls:
- Dial your number from keypad.
- You can use Siri to make a phone call.
- Toggling the speakerphone on and off.
- Plug in your headphones.
