I am not sure if this is an OS issue or not, but taking a chance someone will have a fix. We have two of these phones and they both have an issue where while on speakerphone, it will suddenly and with no discernible pattern or time frame, mute your voice to the caller. You can still hear them but they can't hear you. If you take it off speaker, they can again hear you (or use headphones, I was just learned). Since it's happening on BOTH of our phones and have subsequently found other people online with this issue, they must know about. Am wondering if anyone has any input on this issue. thanks!
