Why is my touch screen unresponsive?

Whenever I try to open an application, my phone does not read it; it doesn't open it at all even though it's on. I don't think the phone is reading my finger movements at all or any clicks.

Restart the phone by holding down the power button until it turns off, wait at least 10 seconds and then turn it back on. This should also turn off all apps that are running, if it doesn't, then try turning off all running apps. If it is still not working you may need to have a corrupted cache and or needs a full factory reset, rifer to Samsung Galaxy Prevail 2 Troubleshooting for a detailed guide on those to steps.
