So since the jellybean update, when i'm at work (or anywhere on wifi) i don't receive any incoming calls. After, i get my voicemail from the call i inevitably missed, but i'm never alerted to any calls. As soon as I turn wifi off, i can receive calls just like i'm supposed to. This inspired me to try some more trouble shooting. I uninstalled google voice and, again, things were great. So i reinstalled google voice (thinking maybe a fresh install would help) and...no dice. Back to the problem. This was never a problem on my old evo or even the GS3 before the update...So, i know there is a simple solution, take the google voice app off and everything will be just great. I shouldn't have to, though...is anyone else having this issue?
