After upgrade no WiFi sync with comcast. No notification from gmail. Xfinity connect app syncs over WiFi but no notifications. Vzw had me do soft reset, hard reset, and finally replaced the device under warranty. New device..exact same issues..including excessive battery drain. Vzw called lg with me on the line..of knew of issue but no resolution other than me sending them my device offering no loaner. Its not a hardware issue. Vzw tried..lg is useless.
