Usually when touch screens don't work, it is due to water damage. You can bring your phone to your carrier's nearest store and ask someone that works there to check if your phone suffered water damage. They'll check the inside of your phone. If that's the case, you'll probably have to buy a new one. If you're insured this shouldnt be TOO expensive. But if you bring it to the store and it's NOT water damage (perhaps a software issue), they should replace the phone for free!
Hope this helped
Please rate my solution!

calibrate your touch screen. pull out battery and put back in, if anything the touch screen s porbably bent from pressure, puttting it in your back pocket could cause this. if calibrating it doesnt work, you need a new touchscreen or a new phone

Hi,possible problem that makes a phone freezes or have a touch screen freeze is Mainly VIRUS affecting a cell phone.

VIRUS affecting a cell phone is caused by downloading and application that has VIRUS, or through data transfer using a USB cable or transfer through blue tooth device.

When a VIRUS affects a phone,it makes the phone to malfunction and freezes.
To remove the VIRUS attack from a phone, you will need to flash the phone to restore back the phone memory to it's default..

Touch component may be broken. Contact manufacturer or look on the internet for a screen to fix it yourself. or go to a cell repair shop

You have to go to MENU->SETTINGS->PHONE SETTINGS->
touch CALIBRATION and press OK when the new settings save.. that should solve the problem. Your phone just needs to be aligned. Good luck

Locate the unlocking key on the right hand side of the unit and press it and see if you are able to enter things with the touch screen. If that doesn't help, remove the battery and the SIM while the phone is turned on. Reinstall battery and SIM and turn on the phone, and test to see if it works. If it still doesn't work, you'll have to return the phone to the place of purchase or nearest authorized repair center.
