Hi Adil,
Do you happen to know when this issue started? Usually restarting or shutting down phone resolve the issue. If not you may want to do reset ( soft or hard ).

When a Samsung cell phone becomes unresponsive or when the device slows to a crawl, a reset may be in order. There are two primary methods used to reset the phone. Users should always start with the soft reset when the phone locks up or programs slow down due to memory or software response issues. A soft reset is akin to a reboot of the machine and usually solves most problems without any loss of user data. A hard, or master, reset is required when the phone completely locks up and becomes unresponsive to any cellular signals. This second and more drastic reset deletes all personal data, preferences and settings so that the device is restored to the original factory configuration.
Perform a Soft Reset
Step 1 Press and hold the power button for 10 to 20 seconds.
Step 2 Release the power button and tap the "Power Off" option under the "Device Options" menu that appears. Tap "OK" to initiate the shutdown.
Step 3 Press the power button again to restart the device.
Perform a Hard (Master) Reset
Step 1 Tap the "Menu" key from the home screen and then tap "Settings."
Step 2 Go to "Privacy" and tap "Factory Data Reset" to review the Factory Data Reset information.
Step 3 Review the Factory Reset options. Place a check next to "Format USB Storage" to clear your device of user data, such as music, pictures and other account settings.
Step 4 Review the disclaimer and verify your changes before tapping "Reset phone."
Step 5 Tap the "Erase Everything" or "Yes" buttons to confirm the reset the phone to factory settings. The device initiates the restoration process to the original factory configuration.
Perform an Alternative Soft Reset
Step 1 Power off the phone. If the phone does not turn off, remove the back cover of the phone and take out the battery. Wait between 10 and 30 seconds and then replace both the battery and the cover to restart the device.
Step 2 Simultaneously hold down the power/lock keys.
Step 3 Release the keys when the Android screen appears.

Tap the little house, then tap Prefs. When in Prefs tap Digitizer or scroll until you get there, or get to Digitzer any way you can. Open digitizer and it will instruct you how to realign your screen. Follow their instructions and you should be back in business. If this doesn't work then you may need to get your PDA repaired. This worked for me in less than a couple of minutes. Good luck

ok, i see your problem.You could clean the screen of your pda using a business card. Gently, wipe the corners of the screen. This is the best way as unresponsive screens occur due to lack of attention as dust migt be trapped under the screen.Hope this works.GOOD LUCK

They can tend to have a freeze now and then Make sure you havent overloaded your memory & make sure your screen isnt slightly open mine refuses to answer ever now & then when someone rings it drives me crazy
