Screen timeout and brightness controls for Android smartphones has always been an issue for many users.
When using apps, mainly for reading, I prefer low back-light with long screen timeout times; for others with more visual elements and colors ( Gallery, for example), I need the opposite.
For example, it can be very annoying to keep to touching the screen to keep the screen on.
The amount of time the screen stays on can be changed with the options 15 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes, and 10 minutes.
So if the phone was set to 1 minute in options, it would shut off after 1 minute with no activity.
Samsung has come out with its Smart Stay technology that uses a front camera to monitor whether the user is looking at the phone screen and keeping the screen on.
This is a handy way to maintain and automatically adjust the screen when reading or using an app.
Below are the steps along with screenshots for both methods.
