If you pull down from the top twice and then click the edit button (to change which of those quick setting things like WiFi, bluetooth, torch, battery saver, do not disturb, etc.) youu want, you’ll find “Visual enhancement” and “reading mode” toggles that are both branded with NXTVISION.
But it is indeed strange that it would connect to the internet.
If it had updated something then maybe, but as your screenshots imply there have been no updates, that can’t explain it.
