He says “Have you ever seen this lock with a circle around it on an iphone?”
I’m not sure, let me google that for you! Google: “lock with circle around it on iphone”
This time I didn’t even have to click on the link. Google just answered my question 🙂
“If you’re seeing an icon of a padlock surrounded by an arrow in your iPhone’s icon bar, it means that your iPhone has rotation lock enabled. Rotation lock allows youriPhone to be locked or “frozen” in portrait mode. In other words, turning your iPhonehorizontal won’t cause the screen to rotate into landscape mode.
