Now also Works with Android 4.2 (Jelly Bean)!
Screen Timeout Toggle is a useful app for keeping screen backlight on even if you didn’t interact with the device for a longer period. When the app is started the system is prevented from switching off the screen after the display timeout. Additionaly a notification appears in the status bar to indicate the current status of the app and to give a possibility to simply reactivate the display timeout. An additional app starter is implemented to disable this notification if you don’t want it.
For easy access there is a widget, that shows the actual status and toggles it by simply one click.
Also a good solution for the Samsung Galaxy S3 which doesn’t give a possibility for keeping the screen on if the device is inactive for a longer period.
If you find problems please email me. I will then improve the app, that will help you and me a lot more than negative comments!
Note: The new app doesn’t change the value of Screen-Timeout in your system settings anymore!
