I installed the update and noticed the signal defaulted to my home wifi right away. There was a popup option instructing me to enter my address so in an emergency like a 911 call I suppose they would know which wifi I was on and hence my location. Also said I should do this whenever I'm using some other wifi? Not doing that every time anyway. Haven't done this yet as it may be undoable once done and not sure if I want to or not. Will be going out shortly so I will see if my signal defaults back to 4G as I expect it will. I double checked my wifi settings to make sure scanning was still disabled, it was. I would think that is all I need do to keep my S6 from trying to connect with every wifi service nearby as I go about my day, and if I need to use this feature while out I can scan for a network. Doubtful I'd use it anytime other than home unless there was no Verizon service but there was wifi service. Like a remote hotel perhaps in the deep woods somewhere that actually has working wifi. A cool feature none the less tho and I did notice on a call it sounded crystal clear. Only made one so far so time will tell. I hope the handoff to 4G calling is seamless once we leave our wifi area.
How's everyone else doing?
