This is one of the most searched-for functions among new iPad users who want their screen to stay in one place instead of bouncing between vertical and horizontal modes depending on what the gyroscope says. Fortunately, it’s easier to lock your orientation than ever before.
Double tap the Home button at any time to open your Control Center. Unless your Control Center has already been heavily customized, you should see the orientation lock in the upper right-hand corner — it’s a circling arrow around a lock icon. Tap that icon, and it will change color, letting you know that the current orientation has been locked. As mentioned earlier, you can also swipe up from the bottom of the screen to access the Control Center.
