Re: phone keeps turning off

I had a friend that just went through this with his Casio "indestructable" phone. They (Verizon Wireless) replaced it free within the warranty time. Worth a try.

Trackpad keeps freezing

Do you have an added Apps? One could be causing the problem.
The other reason could be the pad is getting wet or moisture on it. Also it is not required to press ******* the pad, maybe too much pressure. Also check sensitivity settings
Out of curiosity, have you tried a battery pull yet? While the phone is on, simply remove the battery, for good measure, wait a full minute, then reinsert the battery and wait for the device to reboot.

Does that help? If not, let us know what operating system you're running on your phone. You can get this info under Options > Device > About Device Versions, or by typing "myver" in a text box (e.g. email or BBM).

Nokia 6300 wont turn on, blue lights on side stay on

Hey !
1 . Open the backside of the phone
2 . take off the battery
3 . wait approximatively 10 secondes
4 . back the battery inside & close the phone
5 . switch on the phone
Et voila.

I hope it helps, I have experienced the same and it works for me.

If it don't work try to clean (softly) the sim card and the parts under the battery with air.
