    Check your apps having SYSTEM_ALERT_WINDOW permission, typically screen filter apps or those having device admin rights – beeshyams Jun 20 '20 at 8:32
  • @beeshyams Thanks, doesn't the alert come from Android OS? – Franck Dernoncourt Jun 20 '20 at 8:33
  • Nope. Some installed app. Find out which app has that permission, using any app like this. I haven't used this app, it popped up first on search or use an app from this answer to see which app is causing that "toast" – beeshyams Jun 20 '20 at 8:35
  • On second thoughts, it could be OS toast too responding to restrictions caused by another app, I am not sure but the apps in the second part of the comment above would help – beeshyams Jun 20 '20 at 8:53
  • Googling the toast message hinting on Netflix app modifying display setting...? – Andrew T. Jun 20 '20 at 11:05
