Question:

After One UI 5.0 (T OS) upgrading, I can see 'Maintenance mode' feature newly added in Device care menu.  What is Maintenance mode and What can I do with it?

Answer:

Maintenance mode is a special setting designed to protect your privacy by hiding personal data and information on your device. This feature ensures that your private data remains secure and does not leak out when someone else is using your phone, like during repairs or when sending your device for maintenance.

Here's a breakdown of its functions:

Privacy Protection: Personal data, such as photos, videos, contacts, messages, and call histories, are hidden and inaccessible to the person handling your device.

App Usage Restriction: Only preloaded system applications are accessible in this mode. To use other apps, the user must go through the authentication process again and log back into the apps after exiting Maintenance mode.

Automatic Data Deletion: Any data and accounts created during Maintenance mode are automatically deleted once the mode is turned off, ensuring that your personal information stays secure.

Before activating Maintenance mode, it is recommended to backup your personal data and information to prevent accidental deletion or loss due to unforeseen circumstances, such as an unintended factory reset or component replacements (e.g., main board) during repair processes.
