What device owner means, and why it is the whole thing.
One Android role separates a restriction you can end from one you cannot.
Android was built so a company could hand an employee a phone the employee cannot dismantle. The role that does it is called device owner.
Whatever holds that role sets policy for the whole phone: which apps exist, which can be installed, which settings are reachable. The person holding the phone cannot revoke it.
Consumer blockers do not have it. They are apps beside the apps they block, which is why 2 taps from the app drawer ends them.
The one hard rule.
Device owner can only be assigned on a phone with no accounts on it. In practice that means a factory reset, then a QR code scanned on the setup screen.
This is why it holds. There is no menu that grants it later, so there is no menu that takes it away.
What it costs you.
- A backupthe reset erases the phone, photos and messages included
- 20 minutesreset, provision, choose what dies, set the delay
- Some settingsthe blocker can hold parts of Settings shut, by design
- Your standing to change your mindthat is what you are buying
No root, no unlocked bootloader, no voided warranty. Essentially any modern Android supports the provisioning, and no technical skill is needed past a backup and a QR code.
What it does not fix.
Wiping the phone still works. It is loud, slow and total, which is exactly the friction you want, but it is a route.
And nobody knows you did it. That is the gap: a delay beats the 1am reflex, and only a person beats week 3.
So I do both. I hold the setup with you, then I read one screenshot of your screen time every Sunday for 8 weeks.
