sleep mode locking up

[canrunin]

from time to time when my phone is in sleep mode and i try to use it the lock screen wont work. i swipe my finger across screen and it doesnt open.the only way i can get it to work is to pull out battery and reboot.i have been shutting off phone more often and restarting in hopes that it will help with this problem.if i got to hit the power button to reboot i 'm fine with that but pulling battery all the time sucks.i guess what im asking is should the phone be rebooted 1 or2 times a day to help perform better? it sucks when the phone is ringing and the lock screen is stuck.when screen is stuck the menu button also does not work until rebooted.
