What is Samsung Galaxy Maintenance Mode?

Learn how Samsung Galaxy Maintenance Mode protects your personal data during repairs by creating a secure, limited-access environment using Multi-User Mode (MUM).

Samsung Galaxy Maintenance Mode is a privacy-focused feature designed to protect your personal data when your device needs repair. By creating a separate user account, it hides sensitive information such as photos, contacts, messages, and call history, ensuring only preloaded system apps are accessible. This feature uses Multi-User Mode (MUM) to isolate your personal data and requires re-authentication for app access.

1. How Does Samsung Galaxy Maintenance Mode Work?

Maintenance Mode creates a restricted user environment on your Samsung Galaxy device, ensuring repair technicians can access only essential system functions without viewing your private data. Here's how it operates:

1. When activated, Maintenance Mode creates a new user account using Multi-User Mode (MUM).
2. This account excludes access to personal data such as photos, videos, contacts, messages, and call logs.
3. Only preloaded system apps are available; re-authentication is required to use third-party apps.
4. The device reboots automatically after enabling Maintenance Mode, entering the restricted environment.
