What did you find difficult in removing distractions on Android?
I got a Pixel 5 few years ago (seemingly the smallest form factor Android device), didn't install any apps, removed a bunch of stock apps I didn't need, and turned off notifications for everything beside incoming calls/messages. After that, I just trained myself to avoid using search/the browser unless necessary and to do something else when the itch arises to check the phone for something.
