Can I create a restricted profile on an Android cellphone?

# Background I want to prevent myself from viewing pornography on my cellphone. I do occasionally go to addiction support groups, but haven't yet done the Twelve Steps that they recommend. I'm hoping that, if I set up a sufficiently-good filtering setup, I can manage at least somewhat OK without doing these Steps. I used to use [the app locker formerly known as Smart AppLock](https://play.google.com/store/apps/details?id=com.sp.protector.free&hl=en) in order to try to prevent myself from installing the app which I normally use to view pornography. But the app locker had a bug in it which allowed me to bypass its protection. It's not an obvious bug. I guess I could have tried emailing the developers of the app locker; but I didn't know whether or not they'd actually care. I could have installed a different app locker and given the password to a friend. Or I could have used Pluckeye Lockbox or a similar service to store the password. But I'd rather not rely on third-party app lockers at all. I'd rather rely upon security code written by Google. So I'd like to rely upon Android itself and to make myself a restricted profile in the normal way. I don't want to [install a custom ROM and hope that it can help me](https://android.stackexchange.com/questions/92186/creating-restricted-accounts-on-phone-running-lollipop#95650) . I don't want to [play around with XML files](https://android.stackexchange.com/questions/119117/make-an-iap-in-a-restricted-profile#155761) and hope to achieve my goals that way. I don't want to make myself an [almost-restricted profile](https://android.stackexchange.com/questions/92186/creating-restricted-accounts-on-phone-running-lollipop#96141) . I just want to create an ordinary restricted profile in the ordinary way. # My question If I buy a cellphone running the newest version of Android, will I be able to create a restricted profile for myself in the same way that I could do so on a tablet? And, if so, how do you know? :)
