Help How to effectively block browser access?

[Luke Master]

Hello! I need to ensure that one of my phones DO NOT ALLOW any access to web browsing. Every parental control solution, or application blocking app that I look into, runs into the same limitation: the phone can be easily rebooted into the Safe Mode, which doesn't load third party apps and thus allows unrestricted internet access.
I've looked everywhere and cannot find a solution. The only hope I seem to have is the "restricted profiles" feature that started in Android 4.3. It seems to be able to block apps as desired (I'm not sure how they work because, as the owner of a Motorola Razr XT890, I'm stuck with 4.1). I would be willing to root my phone and install an unsupported version of Lollipop, but I would like to know for certain that the restricted profiles wouldn't run into the same limitation: the ability to easily turn them off with a reboot into Safe Mode. So I'm asking for the help of Lollipop owners to check on that!

Ahh I'd never thought of safe mode rendering app lock apps useless.
Tbh I can't think of a work around other than rooting and uninstalling browser and play store (which is hardly ideal) aorry

Just checked my users guest profile (lollipop) and this seems to be the only option

Yeah, it seems like the restriction option for users is available only for tablets, not phones.
It seems incredible that so far in version 5.0, Google still hasn't made available such a basic feature.

Actually I just discovered I can add another user account but it requires the user to set it up with their Google account ect and I'm not in a position to try that.
Maybe someone else has used it and can tell us about the available restrictions?
