The touch screen of any device deteriorates with use. As a result, you will experience touch delays (especially on the cheaper models) at times and sometimes the touch may stop responding. The app we present to you analyzes your screen response time and reduces it so you can have a smoother experience through an easy and fast process, based on a 3-sample test where you are tossed with your finger. at 4 different points on your screen. This will be repeated 3 times. After completing the tests restart your device and you will really see a difference.
