Mine installed fine (along with 3 other updates). I too am now getting a sound when charging stops, in my case when I take it off the wireless charging plate. There's a lag of a few seconds before it realizes it has stopped charging then makes the sound.
go to settings and Celluar ....turn off your Data and wait a few minutes and turn it back on ...same thing happened to my wife after a soft reset and that was able to fix the problem
