There are a few ways that you can turn off screenshot on your device. The most common way is to go into your settings and find the screenshot toggle. Once you find this, simply switch it to the off position. Another way to disable screenshots is to download a third-party app that will help you do this. There are many of these apps available, so be sure to do some research before choosing one. Finally, if you want to completely disable screenshots, you can root your device. This process is very complex and should only be attempted by those who are experienced with Android devices.
