When I try to listen to audio streaming (BBC, RadioTime app, others), the phone seems to go to sleep after five minutes and, of course, the audio stops. How do I fix this??? Changing screen time-out setting to 30 mins works, but then I can't put the phone in a pocket, have to carefully hold it in my hand and it's probably wasting power to unnecessarily light the screen. I see no other setting to change this...and I know phones not going to sleep *ever* is a big issue for us. Thanks for your help!
