Read full description

The simple app lets you test TouchScreen responsiveness, check its consistency and reliability in registering touches. Background color changes upon every touch during the test. Total number of touches and the coordinates of the last touch are shown on screen. This provides an easy way to verify and demonstrate TouchScreen issues to a Service Center. Equally valuable could be verification and visible confirmation that TouchScreen itself works fine, so that whatever unresponsiveness one might experience in some app, in an element at any place on screen, it could be confidently addressed to that app’s software technical support.
