Just bought a Nexus last Friday. It was fine until Sunday when it updated to 4.2.2. I am experiencing the battery life issues everyone is talking about but I also lost all audio. I can not make or receive phone calls and I can not stream music. Along with the audio issue, my screen no longer turns off when you are talking on the phone. I found an app that enables the audio, but I will eventually have to pay for it once the trial runs out. Is anyone having the same issue, if so, is there a solution?
