Touchscreen will not work on my Samsung Brightside SCH-U380


Other than a bad digitizer (touchscreen) or connection, sometimes just a tiny bit of gunk/debris gets in that tiny gap that goes around the outside of the screen. That often results in the same problem,, a non-working touchscreen. Take a very thin edged piece if cut plastic as a "tool" to clear out gunk/debris from this gap around the edge of the screen. Some people even have used like the opposite end of a sewing needle (not the pointed end).
Many ppl have fixed a non-working screen simply by cleaning out this tiny edge gunk. Give that a shot as a first step. If you use care, you won't damage anything.

Touch screen wont work


Have you tried removing the battery and waiting for a minute and replacing it in the phone.
The phone will reboot and possibly your screen will work again.
