To do so it's easy. Make sure your phone had android 6.0.1 or higher. So, first power off your phone and boot it up again and then hold the power down button and you should be in. Then it will ask you which home app you want to use after your login. Just use TouchWiz home. Then go to Settings > Application Manager then find "kids mode" then click and click uninstall. After it uninstalls restart your phone and you should be booted up in TouchWiz home or TouchWiz easy home and that how you do it. Thanks for reading
