Every time I press the lock button twice quickly when the screen is off it gets locked up. I do this on accident sometimes. Is this always going to be a problem or can it be fixed?

Which button are you referring to? Do you have SGH-I777?

That would be abnormal behavior for the power button. When the screen is off, pressing the button once or twice quickly should make no difference. The screen should come on in either case.

What firmware do you have on the phone? Unless the power button is somehow programmed to recognize a double press somewhere in the firmware, then it is possibly a failing button.

Thank you for helping me. I am running the stable build of Cyanogenmod 10.1 (4.2.2) directly from their website. However, I do not quite believe that my power button is failing. It works fine when i click it once. Is there a way to know if its just a software problem vs a hardware problem? Thanks

Yes, of course. Just flash back to stock and see if the problem persists. I would suggest you try 4.1.2 UCMD8, but it really doesn't matter which version. If the problem goes away, then the issue is in firmware. You should be able to make a nandroid backup of your current configuration, and restore it after you finish the test. (I assume you would understand the necessary steps.)
