That's a radical response to something that might be easy to fix. Try a battery pull ... take battery out, wait at least one full minute for the residual power to drain, put battery back and turn on.
This will take care of a lot of little glitches. It needs to be done from time to time, especially if you've added or deleted a lot of apps. A partial reboot takes place when you turn the X off and on again. Always a good idea from time to time.
Also, don't go crazy with downloading apps. Not all are "friendly" and apps can conflict with your basic operating system and each other. If problems show up after you install an app, UN-install it and see if the problem goes away. Also, do a battery pull after the un-install.
