So late to the party but here you go (especially if you have a boss like mine):
- Install Teams on your phone
- Plug it in so the battery doesn’t drain while your screen is active
- Go to Display and Brightness
- Set Auto-lock to Never
- Launch Teams
- Set status to available
- Don’t touch it at all and leave Teams up on the screen
- You’re welcome and please give credit where credit is due
Teams switches to Away when Teams isn’t the active window on your PC. By having it up on your phone always, it will always be active
