Corporate Password/PIN lock screen got you down? Try this fix to disable. Well here's what worked for me: I followed the instructions posted here to turn on the hiddenmenu and enable the secret tuning codes. Then I activated the Shutdown mode that disables the puzzle lock screen and allows you to turn your phone on and off simply by pressing the power button. "Shutdown *#7594# This enables you to shut your phone off by long-pressing the power/lock key. No more pop-up confirmation. I have tested this and it works successfully. I've also discovered by doing this, it will disable the puzzle/glass unlock screen. Personally, having to push a button and slide the screen is redundant. I like the one-step process." By doing this, i'm also no longer prompted to enter a 4 digit pin which was pushed to my device by our IT department. In an emergency, or urgent situation, nothing is worse than having to enter a 4 digit pin just to get to your phone interface. It's also a pain because the QWERTY keyboard pops up, and then you have to either long press to get numbers, or switch it to number pad....either way, entering a 4 digit pin turns into waaaay more than just pressing 4 digits... Hope this helps someone.
