Power management instructions for Xiaomi/Redmi are wrong
The power management setup instructions for Xiaomi/Redmi devices say "If the padlock is not locked, tap to lock it".
But the button shows the effect of the action (tap to lock) rather than the current state (locked). So if the padlock is already locked, the user should tap it.
- Open the recent apps list (also called the app switcher)
- If Briar has a small padlock next to its name then you don't need to do anything
- If there's no padlock, press and hold the image of Briar until the padlock button appears, then tap it
We also need to check whether the instructions for MIUI < 10 need to be updated.
