I figured it out. Sometimes smartphones will appear to be on and working but will be unresponsive to your touch. If this is the case, your phone is most likely frozen. This is something that does not happen too often but may occur if you drop your phone or have too many applications running. Before jumping to the conclusion that your phone is broken there are a couple things you can try first. First, try rebooting your phone. Hold the power button for about ten seconds. If the phone is unresponsive to this and does not let you reboot, you should try removing the battery. This will shut your phone down and allow you to try turning your phone on. If the problem repeats, the phone is most likely broken and will require replacing.
