I want to use GrapheneOS without the ability to access the browser and without the ability to install new apps. At least without a password. A long one written down on paper would be enough friction for me. You could also give it to a trusted person. You can also write/give only a portion of a password and then memorize the other part.

Afaict there's not an effective way to do this like you can on iPhones with Apple Configurator [1].

Removing appstores from secondary profile and browser with ADB has a workaround (which I won't say in case someone uses that setup). Another drawback is enabling ADB is bad for security.

Dumbphones are stupid because they're overpriced, not secure, and lack awesome apps like maps or Signal. And I already have a phone.

[1] https://news.ycombinator.com/item?id=45171200 this is seriously great if you have an iPhone, I used to use it before I switched to GrapheneOS.

From my experience modified iPhones make the perfect dumb phones that you will actually end up sticking with and it's free if you already have one.

I use this method ^ which lets you keep essential apps but otherwise have dumb phone (no browser, no App Store). Highly recommend.

On the other hand, I have turned my laptop into a dumb computer using cold turkey blocker. I've never seen anyone talking about this here. I'm a standard user (for hardening reasons). And set up so I haven't watched YouTube largely for years because it's blocked and not at all in the past few days. It's flexible to configure and then because it's literally impossible to bypass you never try and then just end up living a calm life. (No ai, no reddit, no crappy news sites, etc.)
