Use Maintenance mode on your Galaxy phone or tablet

To ensure your personal data remains safe when using Maintenance mode, please keep the following in mind:

• As a precaution, we strongly recommend creating a backup of your data before using Maintenance mode. That way, if your device needs to be factory reset during the repair process, or the storage memory replaced, your data will still remain accessible. See the section Back up your data for details.
• A Lock screen is required to use Maintenance mode. When turning on Maintenance mode for the first time, you will be prompted to create a Lock screen if you have not already done so. However, you can also create a Lock screen at any time by navigating to Settings, and then tapping Lock screen. Tap Screen lock type, and then tap your preferred lock type. Follow the on-screen prompts to set up your Lock screen.
• You must have sufficient free space to enable Maintenance mode. Devices with 64GB of internal storage will require 1.5GB of free space. Devices with more storage will require 500MB of free space.

When your device enters Maintenance mode, a separate user account will be created. Then, whoever needs to handle your device (such as a service technician, or even a family member) will be able to use the new user account. This will protect your personal account and data. You can enable Maintenance mode using your device’s Settings menu or by using the Samsung Members app.

Settings menu

1. Navigate to and open Settings, and then tap Device care.
2. Tap Maintenance mode. If you would like to make a backup, swipe down to see your options. See the next section for details about backing up.
   
   
3. Tap Turn on. Follow the on-screen prompts.
   
   Note: You will be prompted to set up a Lock screen if you do not already have one. Please see the previous section for details.

Samsung Members app

1. Navigate to and open the Samsung Members app.
2. Tap the Support tab.
3. Swipe to and tap the Maintenance mode section, then tap Turn on, and then follow the on-screen prompts.
   

When you enable Maintenance mode, you have the option of backing up your data. This is highly recommended. If your device requires resetting or the storage is replaced, you will be able to recover your data from this backup. You can choose between a temporary cloud based backup, or store your backup on external media like a USB flash drive. If your device supports it, you can also use an SD card.

Temporary cloud backup

The temporary cloud backup will upload your data to the cloud and store it for 30 days. After 30 days, your data will be deleted. There is no limit to the total size of your backup, however files that are larger than 100GB cannot be backed up.

1. Once you've chosen to make a backup, tap Temporary cloud backup, and then tap Back up data.
2. By default, all data is selected to be backed up. Tap the check mark next to an item to exclude it from the backup.
   
   
   Note: Not all data can be backed up. Tap Find out what data can't be backed up for details.
3. Tap Back up. If you have Secure Folder set up, you'll be asked if you'd like that backed up as well. If you choose to back up Secure Folder, you'll be asked to unlock it.
4. The backup will proceed. While the backup is in progress, you can use other apps on your phone. When the backup is complete, navigate back to Maintenance mode and turn it on.

External storage backup

The external storage backup requires a USB storage device (plugged in to the USB-C port), or a MicroSD card (installed in your device). This style of backup uses Smart Switch and is suitable for long term backups versus the temporary cloud backup. The total size of the backup is limited to the capacity of your storage device.

1. Once you've chosen to make a backup, connect your storage device, and then tap External storage backup. Tap your connected storage device.
   
   
2. By default, all data is selected to be backed up. You can choose the more limited backup of calls, contacts, and messages, or create a custom backup. Tap Next.
   
   Note: Not all data can be backed up. Tap See what can't be backed up for details.
3. If you have Secure Folder set up, you'll be asked if you'd like that backed up as well. If you choose to back up Secure Folder, you'll be asked to unlock it.
4. The backup will proceed. While the backup is in progress, you can use other apps on your phone. When the backup is complete, navigate back to Maintenance mode and turn it on.

When your device is back in your hands, you can turn off Maintenance mode. Keep in mind that apps and other services that may have been generated during Maintenance mode will be automatically deleted when Maintenance mode is disabled. In other words, your device will revert to the way it was before!
