High Pitch noise....
anyone know anything about this and or why it does it?
I just put 3.1 on, so i will see if the noise continues.
Do any of the following to trigger it.
Send an SMS
Lock the phone
Start recording a video (the whine will play the entire time, and even worse will be recorded by the microphone)
I've also heard it after the "new email" sound plays.
There may be more triggers for it as well. I'm not sure. It's got nothing to do with the screen though, since I've heard it when the screen was off and the phone played the "new email" sound.
Posters on other forums have said the 3.1 beta doesn't fix it. This means either they haven't gotten around to fixing it in software, or that it is truly a hardware problem (with the speaker probably).
That was also when the phone was also at half volume. Not really an issue for me as i can only hear it when i have my ear to the speaker
I have the latest 3.1 beta installed as well
I called Apple Care and they say they have never heard of this issue before, but O2 have agreed to swap out my phone but I bet the replacement still does the same thing!
Totally frustrating and totally annoying. I'm hoping apple fixes this. I keep my phone on vibrate 90% of the time except before bed and during sleep. I can always discern the sound right after the "uuuho" sound plays after an SMS is sent. Then it makes that noise for a good 5 seconds.
