Got Marshmallow update 3 hours ago on Samsung S6 now I can't use Message . I got a text okay but when I try to answer it freezes partway through and will not send. I have restarted and also powered off. That doesn't help.
I would recommend to factory reset the phone after you back up to Verizon Cloud. Here is a link for how to factory reset: Perform a Factory Data Reset (Device Powered On) - LG G3 | Verizon Wireless
Thanks for your response. I was about to do the factory reset when I got a text message and was able to answer it! No idea what happened to make it work again.
