The idea behind Smart Stay is good. The feature is intermittent at best. I had an app on my Droid X that I really liked and finally found it again. It is called Keep Screen. It is free and available in the Play Store. What it does, is keep an app open if you are using it. It bypasses the screen time out function. It is entirely customizable. You select from a list of all your apps or functions. I use it when I am doing emails or other things like checking weather, etc. I find it very useful. I turned off Smart Stay.
