Android devices come with a variety of icons that can be customized to look different on each device. This can be helpful if you want to keep your icons organized, but it can also be confusing if you want to lock icons so that they cannot be changed. To lock an icon, open the app that uses the icon and tap on the three lines in the top left corner of the screen. From here, tap on “Settings.” Under “General,” tap on “Security.” From here, you will see a list of all of your installed apps and their security settings. Tap on an app and then under “Icons,” select “Lock Icon.” This will make the icon inaccessible to anyone other than the owner of the device. ..
