I had to replace the screen and know when it tries to boot it begins to and them freezes half way throught the process and them reboots itself. this continues until i hard reset the phone then it wont turn back on till i turn it on.
I know this is very frustrating michaelehawkins but we are here to help. How did the screen get damaged? If the damage caused other portions of your phone to have issues this may be why the screen is freezing or the phone is rebooting. I recommend clearing the browser history and closing apps you're no longer using. Here are some steps http://vz.to/1sQ1XLX , http://vz.to/1nK1HuI , http://vz.to/1pQDrcv . Keep us posted.
