Samsung launches maintenance mode, a new feature to hide your personal information from prying eyes

The new privacy feature will roll out gradually to Galaxy devices starting with the Galaxy S22, allowing users to block access to their data while their devices are undergoing maintenance.

Samsung Electronics Co., Ltd. global rollout begins today[1] maintenance mode, a new privacy feature available on select Samsung Galaxy devices, following a successful pilot program in Korea and an initial launch in China. Maintenance mode can ease the user anxiety that accompanies giving someone a personal device for repair, by allowing users to block access to their personal information, such as their photos, messages, or contacts. .

“Our entire lives are on our phones, from credit card information to family photos. With maintenance mode, we’re giving extra assurance that Galaxy users can maintain their privacy, even if they give their phone to someone,” said Seungwon Shin, Vice President and Head of Security Team at Mobile eXperience Business, Samsung Electronics. “This is just the latest example of our constant efforts to introduce new ways to make people feel safe and in control, so they can explore new mobile experiences with peace of mind. knowing that we support them.”

Maintenance mode is a way to create a separate user account when you hand in your device for repair so that it can use basic functions without being able to access any of your private information. All the user needs to do is select maintenance mode from the “Battery and device care” menu in “Settings”, and restart their smartphone. As soon as it is restarted, all their personal information including their photos, documents and messages will be restricted[2].

Once the maintenance mode is activated, the person to whom the device was entrusted will also not be able to recover the applications installed by the user. Data or accounts generated while using maintenance mode are automatically deleted as soon as the owner exits maintenance mode. They will be able to download apps from the Galaxy Store, but these will be automatically deleted along with any data or accounts created as soon as the owner exits maintenance mode.

Samsung Galaxy devices are protected by Knox, Samsung’s defense-grade security platform, which offers a multi-layered approach to protection. Through open collaboration with trusted industry partners, any potential threat can be discovered and neutralized faster. Hardware and software security protections built into all areas of the device, from the chips inside to the apps downloaded by users. Real-time protection ensures that security is constantly enforced, day and night. With this state-of-the-art security in place, users can be assured of their privacy. Samsung Galaxy devices enable control and transparency, with features such as Security and Privacy Dashboard and Permissions Manager, so users can easily determine what happens to their data.

Samsung is constantly evaluating and researching new ways to keep users safe. In 2021, Samsung introduced Knox Vault, which isolates the most critical information from the rest of the device. This month, the company unveiled Knox Matrix, its vision for the next level of security across multiple devices. By continuously innovating to deliver the most secure and private experiences customers can trust, Samsung is committed to leading the mobile security industry.


Maintenance mode was successfully tested on the Galaxy S21 series in Korea in July, then launched in China in September 2022. It’s launching globally today, gradually rolling out over the next few months to select models running One UI 5. The rollout will continue throughout 2023, with availability extended to more Galaxy devices. Stay tuned for more information on local availability.
