i have a samsung galaxy centura and out of nowhere the screen just stopped responding for no reason at all wont register my touches at all what can i do
Welcome to Android Central! Any recent drops, trauma, or moisture exposure? Have you tried rebooting, or pulling the battery, waiting 10 seconds, and putting it back in?
If the screen still doesn't respond to any touches after a reboot, then the digitizer may have failed. You'd probably have to bring it to a repair shop (or call Samsung if it's still under warranty).
