I want everyone to know about SMS Popup and SMArt Enhancer. I've tired every popup app I could find for one that does not close my games and despite the claims, these two are the ONLY apps that continued to run in the background. SMS Enhancer is the same as SMS poppy except it had more options and settings. So in conclusion, if you are looking for a small, simple, SMS poppy app that doesn't close your game, check out these two.
