How to safely remove virtual buttons and prevent the bar status from opening?

Question

Android

There are several tablets (with and without a mechanical home button) and I would like to turn off the virtual buttons with the status bar, so that you can only either use the button to exit to the main screen or only use the buttons built into the applications to exit.

Tell me the most correct option to permanently hide the virtual buttons with the status bar, so that 100% does without bricking the device

Answer 1

You know what a problem. After all, you didn’t even indicate the models of your devices, but you want to be given a 100% safe solution.
The fact is that what you are asking about goes beyond the scope of the Android SDK, Google generally does not like it very much when developers try to somehow limit users.
But, for some specific device models, there may be solutions related, incl. with the installation of unofficial firmware, and here, too, no one will give you a 100% security guarantee.
