BTW,everything else checked out OK on my handset.
If you want to perform the system-wide 100% diagnostic test,have a wired headset, B/T headset & a flat surface available.
Not sure if the hissing on playback directly relates to what you hear on a phone call;any input from others more schooled on the subject is definitely welcome.
I ran the audio portion of the test you mentioned above. Yes, when it came to the record/playback and it was playing back my recording, that is the white noise/hissing sound I have been talking about. My problem is that I hear this sound every time a person is talking to me in a call.
At least we now have something others can definitatively test and listen for. I would be interested in seeing what others have to report after running the audio test and then listen for this sound during a call with someone.
Thanks for the test info, Kolio
