Touch Screen wont work?

Put mailing tape across the screen then lift it off. I think that the sceens get stuck together and when you take the tape off it "unsticks them". If that doesn't work you can try to shut down and restart your phone.

How to fix the touch screen on an Android cell phone Is the touch screen on your Android cell phone unresponsive or responding incorrectly? Do some parts of your phones screen respond while other parts do not? When trying to make a selection on your phone does it end up selecting something else instead? Looking for a way to try to fix this and prevent it from happening? Then you have come to the right place. This tutorial describes not only how to test the touch screen on an Android but also what can be done to try and fix it.....Before we really dive in to testing and troubleshooting your touch screen the first thing that you should do is power cycle your cell phone. Simply powering your phone off, counting to 10, and then turning your phone back on can often solve minor software glitches or software hiccups, especially if you haven't powered your phone off for a while. If restarting your cell phone doesn't resolve the issue then we are going to want to verify that the touch screen itself is in fact malfunctioning and that it's not simply being affected by some software problem.

Get it repaired, and try not to dro[ it again!

Did you try restarting the phone...??? If it didn't work try resetting everything. And even if that is not working then I would say it's probably a hardware error. You would have replace your touch panel. Could cost you a little bit. Rush to nearest samsung service center and get it done.
And also bear to put a screen gaurd always. I would not advise you to use touchscreen phones without screen gaurds.
Good luck

It seems to be the problem in the touch itself, it must be changed with a new one.

The usual solution for such a problem is to have your phone's digitizer or touch screen replaced. That is the only solution for your phone's touch screen to work again. Have this done by a cell phone specialist, preferably one who's good with samsung phones.

i've got the same problem with you. my phone wont respond to my commands everytime i charge my phone. sometimes it responds but would respond very slowly as if the interface is lagging. every now and then the phone would freeze and wont respond and wont turn off and only way to turn it off is by removing the battery. anyone else having similar problem? how to fix this?

Have you tried doing a hard shut down? Hold the silver button down on the upper right corner and also the home button (center,bottom indented button) together for about 10 seconds. the phone will completly shut off. then wait about 10 seconds and hold down the upper right hand button until the apple appears on the phone then release the button and wait (20-30seconds) . Doing this usually solves all my issues with my iphone when it gets locked up like this.

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.
