Unfortunately this update has broken a lot of things for me. I'm getting random disconnects - not just in call, sometimes I'll look at my phone and it'll show that I have signal but that I'm not connected. WiFi drops. Bluetooth doesn't connect properly and disconnects a lot, especially to my car radio. I can't get a GPS lock and my phone doesn't know where I am. The phone feels slower and the battery is weaker. I also ran out of data with my cell provider plan this month and that NEVER happens for me, so I suspect something is happening and some background data connection. Android auto is struggling to work and has frozen twice during the map directions. Really disappointed.
I'll give it until Monday to see if a hotfix comes out and then I'll do a wipe. I've found wipes help.
