Today screen

Try turning the Palm Treo off using a Soft Reset.

1. Save your work and close all active programs and games.
2. End wireless connectivity by holding down the red "End" button for 5 seconds.Take off the battery door cover.
3. Remove the battery from the Treo.
4. Press and hold down the red "End" button for five seconds to drain the memory.
5. Insert the battery back into the device and replace the battery door.
6. Wait for the Palm Powered logo screen to appear. The preferences screen will appear and prompt you to enter the time and date.

If you encounter data loss after a soft reset there is a serious hardware malfunction and your device must be serviced.

i think i have the same problem i also pressed reset button and now it doesn't allow me to do any thing please can someone help

Actually, PiyushVig's answer is completely incorrect. The Calendar icon on both the front screen and the main screen are not always there. They only show up for a reason, and that is because there is a calendar event scheduled for that day. (Likewise there is no setting in the phone to show or not show the calendar icon. If you have an event scheduled for that day, the calendar icon will show and there is no changing that feature.)

Today I had the same problem as the person who asked this question. There are no events scheduled for today yet the phone displays the calendar icon on both the main screen and the front screen of my Samsun Convoy SCH-U640 cell phone.

So I just got off the phone with Samsung support to see if I could resolve this issue. They told me that there is no reason for the calendar icon to show up when there are no events scheduled for that day. They had me do a soft boot (shut off phone and remove battery for 20 seconds then replace battery and turn phone back on) and that did not work. I also tried actually programming an event for today and then erased it but that did not make the bogus calendar even alert icon go away.

So Samsung Support's conclusion to this issue is exactly what I suspected before I even called them; it's simply a software glitch (which is annoying for those Convoy users that really use and rely on the calendar function).

1. Turn off HTC Home Sprint and Today Timeout. Settings -->Today --> Items --> Uncheck Today Timeout and HTC Home Sprint
2. Turn off Activesync. This can be done by closing activesync and going to Settings --> Phone --> Services --> Time synchronization and uncheck time sync. This will stop activesync from starting all the time

3. Turn Roaming to "SPRINT ONLY". Settings --> Phone --> Services --> Roaming --> SPRINT ONLY
Open the Task Manager (top right corner icon), clicked on the “tool” icon, then the “button” tab, and changed the “Enable the X button to end running programs,” selection form “End programs by tapping and holding X” to “End programs by tapping X.” Now, when you tap the “X” to close a program, it actually closes, and frees up more system memory. The same result can be achieved by tapping and holding the “X”, rather than changing the setting, if preferred. The objective is to CLOSE the programs and free up the memory.

It seems software problem.Try again reseting the device like that

You can reset your device’s settings and clear all added
data from memory.
Resetting the device
1. On the Home screen, press the Start soft key.
2. Select Settings → More... → Security → More... →
Reset.
3. Enter the reset password and press the Done soft key.
The default password is “0000.”
4. Press the Yes soft key to confirm the reset.
5. Press the Yes soft key to confirm deleting DRM files.
The device resets and reboots itself.

just experienced it myself too, try using THREE fingers to tap the screen TWICE to reset and TWICE to enlarge again...

Occasionally you may need to reset your Pocket PC Phone. A normal (or soft) reset of your device clears all active program memory and shuts down all active programs. This can be useful when the device is running slower than normal, or a program is not performing properly. A soft reset is also necessary after the installation of some programs. If a soft reset is performed when programs are running, unsaved work will be lost.
To perform a soft reset:
o Use the stylus to lightly press and hold the RESET button on the bottom of your device. The device restarts, and then displays the Today screen.
Warning! Always turn off your device before performing a soft reset or installing/replacing the battery.
You can also perform a hard reset (also known as a full reset). A hard reset should be performed only if a normal reset does not solve a system problem. After a hard reset, the device is restored to its default settings-the way it was when you first purchased it and turned it on. Any programs you installed, data you entered, and settings you customized on the device will be lost. Only Windows Mobile software and other pre-installed programs will remain
To perform a hard reset:

1. Press and hold both soft keys on the device. Keep these keys pressed, and at the same time, use the stylus to lightly press and hold the RESET button on the bottom of your device.
2. Release the stylus but keep the soft keys pressed when you see the following message on your device screen. "Do you want to erase all user data and restore to manufacture default?" will appear.
3. Slide open the hardware keyboard, and press R to restore to factory default or press X to exit the hard reset process.

Hope this helps, let me know if I can help you with anything else.
