So I have been using this app on my older phone called Viber. Its a VOIP app that lets you send free txts and calls to others who have this. Anyway, putting this on the LG Spectrum seems to not work well. The problem is I can hear the other person fine but they can not hear me at all. Well they can hear a little something but can not understand what I am saying. When I plug my headset in then they hear nothing at all. I have tried this on WiFi and 3/4G with the same. Any ideas or tips? EDIT: Seems to be a mic issue of some sort. The volume at other callers hear me is extremely low. This happens in Skype too. Is there a way to boost the mic pick up?
