In the Lenovo Z2 Nougat (ZUK) there is no activity to open Settings.ACTION_MANAGE_OVERLAY_PERMISSION (settings screen that shows draw on top permission).
The activity works on all other devices though.
This is a device manufacturer problem and there is no clear documentation or alternative documentation.
Clicking the Review Permissions button in Anti-malware does not work. User will have to manually find this setting and change it if needed.
