<span id="INSERTION_MARKER"> I have a Samsung T669 touch screen phone and it's been fairly nice to me up until this point. A few days ago, the screen stopped working completely. No matter how many times I pressed my fingertip against it, nothing happened. The phone has a keyboard so I just navigated using that but today when I restarted my phone, the keyboard no longer responds. AT ALL! I really need my phone to work. I have to use my phone regularly for work. I need to know if anyone knows of a quick fix to this problem or am I doomed to make the trip to the T-Moblie store to purchase another phone? HELP PLEEASE! Thanks!
