So I just got a upgraded to the Lumia 820 a few weeks ago. The more bluetooth devices I use for audio playback the more I notice the audio quality is terrible. I have a jambox and a bluetooth car stereo both have the same issue, It tends to give off an occasional hiss or sqeal as it plays music. With the aux cable and headphones the audio quality is superb, ruleing out MP3 audio quality. I did the update (1249.00001) still has the issue, it never did it on my previous handset (Samsung focus Flash 7.5) and I have even turned off all my connections except bluetooth to rule out interference. Anyone else have this issue? Is it my handset? or is it software? I would like to know befor my warranty becomes an issue. Thanks!
