Just wanted to mention i had issues with random rebooting since the first day Marshmallow up came out. Tried everything, formatting, new phone you name it. Finally narrowed it down to Iheart Radio app. Iheart is aware of problem. Fix is to download older version at "http://www.apkmirror.com/apk/iheartmedia-inc/iheartradio/iheartradio-5-13-0-release/iheartradio-5-13..." do not let it update. So far working great for 2 days.
