Answer to: Why is my touchscreen not working?If restarting it doesn't work the screen may be dirty. To fix this you'll need to clean the screen with a clean slightly damp cloth. If you have a screen cover try removing it and then restarting the phone. You may have to force a restart. Also make sure that your hands are dry and clean. If you're using a stylus make sure the tip is clean. I usually wipe mine with an alcohol wipe. I hope these tips help. Good luck!
