[Q] Mic crackle with Wi-Fi enabled?
So a friend of mine has a Sprint Galaxy S3 running the latest official Jellybean 4.1.2 that the phone came installed with. The phone has issues with transmitting voice audio, specifically when WiFi is on. To elaborate:
-When talking on the phone with a headset plugged in, my friend's phone emits an intermittent buzzing noise that is audible to the person on the other end, but not her. The noise lasts for a moment, and then goes away. It sounds exactly the same every time it is heard, but happens at random times.
-Whenever using VoIP apps such as Skype/Google Hangouts with a headphone mic plugged in and WiFi on, an extremely loud static/crackling noise is heard by the person she is talking to. The moment WiFi is disabled, the crackling/static is gone, and the other person hears her clearly. Again, she does not hear any of this noise, the person she is talking to does.
-Unplugging the headset in both occasions and using the phone's mic nearly eliminates the amount of static heard. However, in VoIP apps, again, static is heard by the person she is talking to when she speaks, but is less noticeable than with the headset plugged in.
-In all instances, the static/buzz is gone when she disables WiFi and uses mobile data while talking on the phone or Skype/Hangouts.
I've tested this issue with her and the noise is similar to the rapid tapping of a Geiger counter. Is anyone familiar with this issue? Is there a fix? She returned the first phone for a second, and both have the problem. If there's no solution, she is highly considering returning the GS3 and seeking a different model. Thanks!
