In this article, we will explain how to lock and unlock your screen orientation on an iPhone, discuss the pros and cons of this feature, and provide some additional information to help you make the most of your device.

After completing the action of locking or unlocking your iPhone’s screen orientation, the immediate result will be that your screen will either stay in one orientation (portrait or landscape) regardless of how you hold your phone, or it will rotate with the movement of your device.


The iPhone is a marvel of modern technology, isn’t it? With every new model released, there are new features and functionalities to explore. However, sometimes it’s the simplest things that can cause the most confusion. One such feature is the lock icon at the top of the iPhone screen. It’s a small detail, but for those who are unaware of its purpose, it can be perplexing. Why is my screen not rotating? Is there something wrong with my phone? These are common questions that can arise.

Understanding what the lock icon represents is important, especially for new iPhone users or for those who may not be as tech-savvy. The lock symbol indicates that your iPhone’s screen orientation is locked in either portrait or landscape mode. This is particularly useful when reading an e-book, playing a game, or watching a video and you don’t want the screen orientation to change if you move your phone. It’s a feature that enhances the user experience by giving you control over how you want to use your device. So, let’s get into the nitty-gritty of how to use this feature and what it means for your iPhone usage.

Step by Step Tutorial: Locking and Unlocking your iPhone Screen Orientation

Before we dive into the steps, it’s important to know that following these instructions will enable or disable the screen rotation lock on your iPhone. This is handy when you want to keep your screen fixed in one orientation.

Step 1: Access Control Center

Swipe down from the top-right corner of the screen to access the Control Center.

Accessing the Control Center is your gateway to many of your iPhone’s handy features, including the screen orientation lock. If you have an iPhone with a home button, you’ll swipe up from the bottom edge of the screen instead.

Step 2: Locate the Lock Icon

Look for the icon that looks like a lock with a circular arrow around it.

This icon is usually located near the top right of the Control Center. It’s easy to spot once you know what you’re looking for – a little padlock encircled by an arrow.

Step 3: Tap the Lock Icon

Tap the icon to lock or unlock your screen orientation.

When the icon is highlighted, it means that the screen orientation is locked. When it’s not highlighted, your screen is free to rotate.


Prevents Accidental RotationWhen reading or watching something on your iPhone, it’s annoying when the screen rotates just because you shifted your position. Locking the screen orientation prevents this from happening.
Enhances User ExperienceWhether you’re lying down or working out, having control over your screen orientation ensures that you can use your iPhone in whatever way is most comfortable for you.
Useful for Certain AppsSome apps and games are best enjoyed in one screen orientation. Locking the orientation can enhance the functionality of these apps.


Can Be ConfusingIf you’re not aware of the lock feature, you might think your iPhone is malfunctioning when the screen doesn’t rotate.
Requires Manual TogglingYou have to manually lock or unlock the screen orientation, which can be a hassle if you switch preferences often.
Not Applicable to All AppsSome apps don’t support rotation lock and will rotate regardless of the iPhone’s lock setting.

Additional Information

When using the lock icon feature, it’s important to remember that not all apps will adhere to the lock. Some apps, particularly games and video players, have their own rotation settings that can override the iPhone’s lock. Additionally, there are times when you might find the lock engaged without your knowledge. This can happen if you accidentally enable it when swiping into the Control Center. So, if your screen isn’t rotating and you’re not sure why, it’s always worth checking the lock icon first.

Another tip is that if your Control Center is becoming cluttered, you can customize it to only include the features you use most often, including the screen orientation lock. This way, you can access it even more quickly.
