A phones screen freezing or being unresponsive can be attributed to many different factors. Often times a simple reset of your device will clear up issues that are causing your device to freeze or become unresponsive.
Press and hold the power button until the phone shuts down, wait 1 minute, turn it on.
If your phone has a removable battery, take the back cover off, take the battery out, wait 1 minute, re-assemble the phone and power it back on.
If its intermittent, check the phones memory space, if you are running low, this may be the reason for the phone freezing, delete files, text or pictures that are no longer used to free up space.

Press and hold the Volume Down and Power keys simultaneously until the device reboots. Typically this will take 11-12 seconds.
Release the keys when you see the LG bootup logo
