Wondering if anyone else has experienced this problem: Around the middle of October 2014 I started to experience odd behavior on my SG 4 SCH-I545 from Verizon, and I have researched the issue extensively with no solution. Unpredictably, I cannot hear the audio when I make an outgoing call. I know that the call goes through because I can hear the call initiation tone on my cell and the outgoing ringing. When the call is connected I cannot hear the person's voice (nor the recording if I'm calling a service such as customer care). I've verified that the call goes through by calling my home phone and friends - they can hear me but I can't hear them. The only fix is to restart my phone. The reason I say this behavior is unpredictable is due to the fact that I am able to successfully make and hear outgoing calls a few times, then the audio failure happens randomly. I haven't noticed a consistent pattern (such as after making x number of calls or my location). Here's the only consistent thing I've noticed: after I restart my phone I see an app update (or 2 or 8 or however many are available) going in the status bar. It seems like the pending app update is interfering with the audio for outgoing calls and is "stuck" waiting to be downloaded until I restart the phone. I have Play Store updates enabled only on wi-fi, and I know that wi-fi has not gone down when my phone needs restart. The apps that update after phone restart come from the Google Play store. Verizon suggested that the problem could have been caused by an app that was updated after mid Oct 2014, but there have been SO many updates since then, and I'd really prefer to avoid the tedious task of factory reset, install 1 app at a time, and test.
