Just got the update. WiFi calling (and presumably wifi texting for MMS?) Is much appreciated considering the poor cell connection I get within my house. Here's a pic of my software info (cropped out some unnecessary info)
For all those having issues after the update. My suggestion would be to do a full factory reset of your device, as sometimes this is required, for some devices, after an update.
I have ATT and have Wi-Fi calling on and I am able to quick charge. However, I have noticed my battery life has gone way down. I'm gonna turn off the Wi-Fi calling and see if that helps.
