My Galaxy active touch screen stopped working today. The buttons still work. The screen acts like its got something trying to touch it. Without prompting it will scroll to different apps. Periodically I can swipe from right to left but then it goes haywire again. Every once in a while I can intentionally scroll and was able to do a hard reset. I have restarted with the power button, hard reset, updated apps as best I could. Sometimes the green lights on the back still check my heartbeats. There has not been any damage to it. Any suggestions?
