I haven't noticed anything unusual. Had a couple of conversations going until about half an hour ago. (In NJ and using Yaata SMS, either of those matters.)
No Problem at all. (VZW Samsung N8 "Messages" app, NC/SC).
I use to use YAATA Pro, it's an EXCELLENT SMS/MMS app. I loved it but the Note 8's new Samsung messaging app has a lot of customization so I decided to stick with it. At least for now. The text app on my N4 had next to no customization.
Yesterday, I did have a problem when calling other Verizon customers. I couldn't get a hold of my wife or a coworker, both on Verizon. At first I chalked it up to me being in Japan, but I managed to call another coworker who was on AT&T. After about 15 minutes or so, I managed to get through to my wife. We could text just fine. When my wife or coworker called me, or when I called them, the call would drop as soon as it was answered.
Thanks all, not sure what was happening but after a few restarts, it fixed itself. Notifications would show up all at one time and later than usual. Much appreciate the input.
