I'm searching an app on Android (share iOS too) that can make my smartphone a dumbphone, but the app cannot be uninstall by me, or pretty hard to uninstall it. Because, many times I've install some app for that purpose, but I uninstall it, and that's it. I'm searching something that cannot be uninstall that easy, BUT IT DOESN'T MEAN THAT I CANNOT UNINSTALL IF I'M NOT A HACKER HAHAHAH. Do you have any? Because I'm really committed to do it, but it doesn't work if it's that easy to uninstall it
