Folks, I have been having a minor problem just recently where if the phone is on Speakerphone (Green light on button is lit), and in the middle of a call, without warning the sound suddenly stops coming from the speaker on the back and jumps to the earpiece on the front instead. When it does this the Green light on the button stays lit to indicate Speakerphone on, but it operates like a normal phone call with the earpiece. It seems to have happened a couple times when the person on the other end says something LOUD. This will continue to operate during the call this way if I don't then turn OFF speaker phone and then turn it ON again. If I do that then the phone works fine again. This is something that I can't reproduce on demand, it happens sometimes and doesn't others. I don't use Speakerphone that much so I don't know if it's been a bug in the phone from the beginning but I doubt it since I've only noticed it recently. Has anyone else experienced this? For reference, I am NOT rooted, but I AM running the un-official 6.12.173 update. This update has been a very nice improvement in many features and operation so I do expect it will roll out soon in some form but not likely .173.
