How to set up BIOS-like password on Android device? Setting a screen lock password or SIM pin or both is fine for securing some aspects of your mobile device. But what if, as a nasty joke, someone manages to grab a hold of your device and hits the magic power-home-volume key combination and proceeds to factory reset your device thus deleting your folder configuration, a record of what unpaid apps you had downloaded, and what is more, data stored on your phone!

So, is there a way to set up a password so that it must be entered when such magic key combination is issued (so that you can't factory reset your device without entering such a "BIOS" password?

Thanks!!!
The only thing similar to this that I can think of is device encryption, it's built in to the settings panel. Every time you power on your phone, you are required to enter a pass-code, that you created. If you forget it, it will be more difficult to get back into your phone

How To


Go to settings
Click Security
Under the Encryption group, hit Encrypt device (or phone on older devices)
Now it will guide you through the next steps.
