After a recent software update my phone stopped working when I made or received a call. I couldn't hear anything, not even a dial tone, and the person on the other end couldn't hear me talking either. I am still able to make and receive calls when connected to Bluetooth. Speaker phone will not work either, but I know my speaker is working (I can play music and game sounds work). My earpiece is working as well because I get the call connection "beep" when placing calls. I tried pulling the battery and resetting the phone but the problem still exists.
I see this is an issue on multiple GS4 phones from a number of different carriers. It seems to be a software glitch to me, as the associated hardware seems to be functional.
Is Samsung aware of this issue? Does anyone else have this problem?
As I mentioned, I first noticed it after my phone updated over night. The update info is below.
