Device test: compass and permission
Running as: …. Nothing here leaves the phone.
1. Does the permission persist?
Last answer recorded on this phone: none.
Orientation events since this page opened, without asking: 0
- In the installed app, tap Ask and allow.
- Close the app completely (swipe it away), then open it again from its icon.
- Come back to this page and do not tap Ask. If the events number climbs, the permission persisted.

- Lay the phone flat and note the values.

Noted values stay on this screen only; take a screenshot to keep them.
