Accessible Features
In Maintenance Mode, users can still access many basic functions of the device. The home screen displays a limited set of pre-installed apps like Camera, Calculator, and Settings. Users can browse the internet using Samsung Internet browser, but without access to bookmarks or browsing history from the main account.
Phone calls can be made, but the contact list is hidden. The Gallery app shows only photos taken during the Maintenance Mode session, keeping your personal media secure.
The system allows testing of hardware features like speakers, microphone, and camera functionality. This is particularly useful when sending your device for repairs.
Limitations in Maintenance Mode
While in Maintenance Mode, access to personal information is strictly restricted. Users cannot view or interact with the main account’s contacts, messages, or photos. Downloads and app installations during Maintenance Mode will be removed once the device returns to normal operation.
The mode prevents access to sensitive information such as saved passwords, payment methods, and accounts. Samsung Pass data remains protected and inaccessible.
Some diagnostic tools may experience limitations, as reported by some repair centers. According to user experiences, certain service technicians found that they couldn’t perform all quality checks with their diagnostic software while the device was in Maintenance Mode.
Any changes made to settings or configurations during Maintenance Mode will not affect the main user account settings.
Exiting Maintenance Mode
Samsung’s Maintenance Mode is designed to protect your privacy while your device is being serviced. Getting out of this mode is straightforward but requires specific steps to restore your device to normal operation.
Disabling Maintenance Mode
The most common way to exit Maintenance Mode on Samsung devices is through the Settings menu. Users can navigate to Settings > Device care > Maintenance Mode and tap Exit, followed by Restart to disable the feature. The system will then prompt for lock screen credentials before proceeding with the restart process.
If the notification panel is accessible, users can also exit by pulling down the notification panel and tapping on the Maintenance Mode notification.
For those who cannot access Settings because they’re stuck in Maintenance Mode, using the Samsung search function provides a solution. Simply swipe up on the home screen, enter “maintenance mode” in the search bar, and select the relevant option to exit.
Returning to Normal Functionality
After exiting Maintenance Mode, the device restarts to restore all basic functionalities. This process typically takes a few minutes to complete. During the restart, the system reinstates access to personal apps, accounts, and data that were temporarily hidden.
Users should verify that all apps are functioning correctly after the restart. Sometimes, certain applications may require re-authentication or additional setup steps after exiting Maintenance Mode.
Personal information that was protected during maintenance becomes accessible again. This includes photos, messages, contacts, and any accounts that were temporarily restricted.

Maintenance Mode on Different Samsung Models
Samsung’s Maintenance Mode feature is available on various Galaxy devices, but it works differently depending on your phone model and software version. The implementation varies between the S21 and S22 series, with improvements made as Android versions advanced.
Galaxy S21 and Maintenance Mode
The Galaxy S21 series was among the first to receive the Maintenance Mode feature through the One UI 4.1 update. On these devices, users can access Maintenance Mode through two different paths. The primary method is through the Settings app, where users need to navigate to the Device care section.
From there, tap on Maintenance Mode and follow the on-screen instructions to activate it. The phone will restart in a restricted state where personal data remains protected.
The S21 series also offers access through the Samsung Members app, which some users find more convenient. This method requires fewer steps but achieves the same result.
When active on the S21, Maintenance Mode creates a temporary user profile. This profile cannot access personal photos, messages, or accounts. Any apps downloaded during this mode are deleted once you exit.
Galaxy S22 and Android 13 Compatibility
The Galaxy S22 series features a more refined implementation of Maintenance Mode, especially after receiving the Android 13 update. On these devices, the feature is more deeply integrated into the Battery and device care settings.
Galaxy S22 owners benefit from enhanced security protocols. The Android 13 version creates stronger separation between the temporary profile and the main user data. This makes it nearly impossible for repair technicians to access personal information.
One UI 5, which comes with Android 13, also improved the user interface for Maintenance Mode on the S22. The toggle is more prominent in the settings, and the activation process requires fewer steps.
Unlike some earlier implementations that were criticized as potentially gimmicky, the S22’s version allows repair shops to run most diagnostic tools without compromising privacy. Samsung also added clearer explanations about what data remains protected during repairs.
Optimizing Your Device

To optimize your device manually, navigate to Settings, then tap “Device Care.” The system will analyze your device and provide a performance score out of 100.
For instant improvements, tap the “Optimize Now” button. This action closes unnecessary background apps and clears cached data that might be slowing down your device.
Users can also set up automatic optimization by enabling the “Auto optimization” option. This feature will schedule regular maintenance during idle periods, often while you sleep.
Clearing Memory and Storage
Managing memory and storage is crucial for maintaining device performance. When your Samsung device begins to slow down, clearing RAM can provide immediate relief.
Within Device Care, tap on “Memory” to see current usage. The “Clean Now” button will close unused apps running in the background, freeing up RAM for better performance.
Storage management is equally important. Navigate to the Storage section in Device Care to identify what’s consuming space on your device.
Large files like pictures and photos often take up significant storage. The system identifies unnecessary files like duplicate photos or downloaded images that can be safely removed.
Samsung’s optimization tools also detect and remove temporary files and app cache data. These files accumulate over time but serve no long-term purpose.
Regular cleaning sessions ensure your device maintains optimal performance without manual intervention.
