The iPhone is all about accessibility and ease. It offers certain features that you wouldn’t find on any other device. Even if you do, the quality or interface wouldn’t be as good in most cases.

One such feature that we will be discussing today is ‘Shake to Undo’ on iPhone. This feature allows you to easily undo and redo while typing by shaking your iPhone. Now, you don’t need to keep hitting the backspace key to delete a sentence that you just typed, rather undo it with a simple shake.

However, many users have complained that the undo prompt is displayed even if they shake their phone by mistake. This can be construed as a major drawback my many, therefore, before you enable and start using the feature on a regular basis, try it for a day or two to check if it suits you.

Enabling Shake to Undo from iPhone Settings

Before you can use the ‘Shake to Undo’ feature, it needs to be enabled from the settings. To enable it, tap on the ‘Settings’ icon on the iPhone home screen.

Next, scroll down and tap on ‘Accessibility’ from the list of options in the settings.

In the ‘Accessibility’ settings, tap on ‘Touch’ under ‘Physical and Motor’.

In the ‘Touch’ settings, check if the ‘Shake to Undo’ feature is enabled. If it isn’t, tap on the toggle next to it to enable the feature.

How to Use the Shake the Undo Feature while Typing

To use the Shake to Undo feature, type something in either the text box in the ‘Messages’ app or the ‘Notes’ app or any other app where you can type on your iPhone. For this article, we will be using the ‘Notes’ app. But, do keep in mind that not all apps available on the App Store support this feature.

After you have typed something, shake your phone sideways to undo it.

After you shake your iPhone, a prompt will appear on the screen. To undo the changes, tap on ‘Undo’ in the prompt. If you shook the phone by mistake, tap on ‘Cancel’. The iPhone does not automatically undo the change but asks for confirmation, which ensures that you don’t end up losing text if shake your iPhone by mistake.

To redo the change, shake your iPhone once again. You will now find another prompt on the screen with the option to both ‘Undo’ and ‘Redo’. This will only be the case when the option to ‘Undo’ is available. For instance, in this example, before writing ‘’ (as seen in the above screenshot), we wrote ‘A’ which can be seen in the picture below. So, when we undid earlier, we reverted from ‘’ to ‘A’. Now, if we again chose ‘Undo’, the complete text will disappear while in the case of ‘Redo’, we move back to the earlier text, i.e., ‘’.

Once you get oriented to the ‘Shake to Undo’ feature, it will be your go-to tool to undo and redo changes. Also, after you get oriented, typing on your iPhone will be a lot simpler and more convenient.
