What is maintenance mode in Samsung Galaxy phones?

Maintenance Mode in One UI 5 protects your privacy by protecting the data on your phone from prying eyes. The mode is intended for use when you send your phone for repair as you don’t need to format it in such scenarios. Instead, activate maintenance mode and send the phone to the service center without worrying about the technician accessing your personal data.

Back up important data before sending your phone in for repair.

Maintenance mode prevents access to your accounts, photos, files and other data stored on your phone. The technician only has access to pre-installed apps. They can also download and install new apps from the Galaxy Store, change system settings, sign in to their Google Account, access the Play Store, and run their diagnostic tools without any issues.

When maintenance mode is turned off, the data is lost and the device is restored to the same state as before the mode was activated.

Maintenance mode creates a separate guest account on your Galaxy device, which the repair technician can use for the test work. This also ensures that they do not gain access to your personal data on the device. Maintenance mode is why multi-user support is missing in One UI 5 despite the option being available in the first builds.

This feature is only useful when minor repair work has been done on your device. It will be of no use if there are significant issues that require a logical replacement or a complete system format. In such situations, you must make a backup copy of your data before handing over the phone to the service center. Otherwise, you risk losing all data.

Devices compatible with maintenance mode

Samsung trialled maintenance mode on the Galaxy S21 series in South Korea in July before expanding to China in September 2022. The feature is available on select Galaxy devices globally running Android 13-based One UI 5:


Samsung will continue to expand the availability of maintenance mode to more of its phones and tablets in the future.
