My wife has been happy with her S5 phone since last December but about a month ago the outgoing voice started fading in and out making it very difficult for the other party to understand her. Incoming sound is fine and it does not drop calls. Text messaging and internet browsing (even with WiFi disabled) are fine. The problem is particularly bad at home where we get a solid 2 bars signal strength with 4G. My S4 works fine in the same place. The voice recorder works perfectly so it's not a microphone problem. The software is up to date and I've done a factory reset - no change. Samsung support had me load a diagnostic app but they could see nothing wrong. Verizon support tried a network remedy that made no difference either. I finally got a replacement phone from the Verizon store - no improvement. This phone worked fine for 10 months and now is practically unusable for voice in my home. What's up?
