We can definitely provide you with some troubleshooting steps for when your cell phone's screen is frozen or unresponsive. Please go ahead and force restart your device by pressing and holding the Volume Down and Power/Lock buttons simultaneously for 10 seconds, until the device restarts to see if that resolves the issue. We also recommend using our Troubleshoot and Resolve Tool to fix screen issues. Simply select your device and the issue, then follow the steps to find a solution. Let us know if this helps.
