I have downloaded my audio book, and the note 3 is constantly looking for a network connection even though I have wifi shut off (to save battery) constantly interrupting the audiobook. The phone is in my pocket when I am working and bending down also activates that s-voice telling me " I can't find a network connection". I have shut off everything I can think of and even put it on airplane mode. Why is it looking for a connection when the audio book is fully downloaded (not streaming)?
