Hi, Can anyone suggest an app that will automatically shutoff my Samsung S4 after a set period of time? What I use this for is I may be listening to a Netflix or HBO GO movie (yes I know, "listening") and I want the phone to shutoff after 30 minutes. I was having a hard time finding any app that does this. Google searches just showed me results of shutdown problems, and the apps I came across were to reboot the phone. Thank you for the help.
