Duet Not Working in Tik Tok – What to Do

Duet is surely one of the features that make TikTok stand out from the rest of the similar video-sharing social networks. It allows you to create a short clip with a person you hold dear, a friend, or even a celebrity. And the final result is a funny side-by-side video of you lip-syncing to whatever tune or video you like.

However, this feature might not be working for some users or it doesn’t appear at all. There is no need to worry since you can get Duet up and running with a few simple software tweaks. The following sections will provide you with all the tips and trick you’ll need to fix a faulty Duet.

How to Repair Duet in TikTok

App Update

Since Duet is a relatively new feature, it might not work or be available if you are running an older TikTok version. To check for updates, launch Google Play or App Store and tap on the Updates tab.

Browse for TikTok and hit the Update button, if the app appears under Updates. Once you install the latest software, re-launch the app and try to make a duet.

In-App Duet Settings

For most users, this is where the problem with Duet lies. To be precise, TikTok has very specific privacy settings and Duet might be disabled or limited from the get-go.

To make the necessary changes, tap on the profile icon at the bottom right and select three horizontal dots to access the More menu.

Tap on Privacy and Safety in the following window, navigate to “Who Can Duet with Me”, and make sure it’s on. There are three options, Everyone, Friends, and Off. If you want some additional safety you can put the settings to Friends.

Note: If the other party has Duet set to Off, you won’t be able to duet with that user. If it is set to Friends only, make sure you’re friends with them beforehand.

Good Old Restart

What happens if you’ve updated the app and got all the settings right but Duet still doesn’t work? In this case, it’s best to restart your smartphone to see if it helps.

A simple restart or soft reset resolves minor software issues and bugs that might be preventing you from making a duet. In addition, it also clears the app cache data that could be the culprit.

The restart/soft reset method depends on the device you are using. In general, you need to press the Power button and/or one of the volume rockers. For example, it’s Side button plus one of the volume rockers on newer iPhone models.

Clear App Cache

If all else fails, you might need to clear the app cache to make Duet work again. The method is a bit different on Android and iOS, check out the necessary actions below.


Launch Settings and select Storage to access more menus. Tap on Other Apps to preview the list of all installed apps and navigate to TikTok. Once you access the TikTok window, hit the “Clear cache” button and you’re done. You should know that this doesn’t remove your login information and saved data.


Tap the Settings app, select General, then iPhone Storage. This gives you a list of the apps and the amount of data they use. Swipe down and tap on TikTok to access the settings window. Select “Offload App” to remove all the cached data from the app.

This basically uninstalls TikTok but saves all the important data. Once you finish, head over to the App Store and reinstall the app. You can also do it from the same window immediately after the offload.

Important Notes

The previous steps apply for the latest iOS and Android software. Those who use Android Oreo need to access App Manager from Settings and proceed from there.
