My Note 2 is just 2 weeks old and I only noticed yesterday that while the microphone works perfectly well otherwise, if I turn the phone on speaker mode, the microphone gets disabled.
It doesn't matter if it's a regular call or Gtalk or Skype or any other call. But on speaker mode the microphone does not work.
What can I do? I don't want to give it to service just for this if there's something I can do myself. Software reload? Settings? Someone please guide.
