Well it didn't work for my Galaxy S22+. I tried about 5 different configurations including "Developer Options". On my first try I set it to "1 hour", but it just reverted to 10 minutes. There are so many different ways to set it up. I'm sure it would work if I only knew which settings on my phone should be turned off or on. Maybe it's not working because of a setting in "Developer Options" which I have a bad habit of tinkering with! ✌️

Works exactly as described. My company gave me a one minute timeout. Most of the time it's not an issue, becaue the apps I use can keep the screen open, or I don't need that much time not interacting with my phone. It is nice to have for other apps though, so I just set it to on when I need it, and have it turn off automatically when I don't use it. Good app!

This program is fabulous. He's thought of everything. When you need to keep an app running and not log you out of your phone and shutdown, this will do it. Move the icon up next to bluetooth, and when I use Chirp to do books, through bluetooth speakers, I click bluetooth and caffeine on. When I'm done I turn them off. If I forget, it goes off when the phone shuts down anyway. Allows allows for dimming the screen. Perfect program.
