It's possible yes. You can also take the phone out of the case. I do this sometimes when i need to scan a QR or something. It doesn't stop people from doing it

It's possible yes. You can also take the phone out of the case. I do this sometimes when i need to scan a QR or something. It doesn't stop people from doing it deliberately but it prevents the discussion between people holding up a phone and someone else thinking they're being filmed. If someone does that without the sticker it is immediately cause for calling security.
