For users who turn in their Galaxy phones for repair, Samsung is adding a new function called “repair mode.” There’s a good chance you’ll want to secure your data before sending your phone off, and the new function seems like a perfect way to accomplish that. However, it does not protect your phone.
It’s difficult to deal with data when it’s sent in for repair through mail. However, if you want to get rid of the data on your phone, you may do so by deleting it. When sending in a device that is entirely locked down, technicians will not be able to adequately examine it since they will be unable to access any of its features. However, when in repair mode, professionals are able to access your device’s default applications and test everything, but they will not have access to data. You may re-authenticate and deactivate repair mode once you have your device back, and all of your data will be restored.
Samsung has only confirmed the feature in a Korean press release; it will be available in Korea for the Galaxy S21 (Samsung’s most recent flagship phone), which was identified by SamMobile first. While in repair mode, Samsung explains (via Google translation) that “you won’t be able to access your personal data, such as images, messages and accounts,” so anybody who has the phone may “use the default loaded applications.” Samsung’s repair mode can be activated from the settings menu. To escape repair mode, use a pattern, pin, or fingerprint to verify your identity.
Since Android already has a variety of features that may be used to achieve this feature, it’s not clear exactly how it works. There are several user accounts available on Android, allowing for various sets of applications and data to be installed. In order to make things easier for the repair team, the principal account might be locked down and a “guest” user created with no data. Alternatively, it’s conceivable that Samsung is encrypting all of the user’s data. It is possible for repair specialists to get access to the read-only system partition, which contains all of the OS files needed for testing, as well as a temporary data storage.
Any way the functionality works, we think it’s a fantastic concept and one we’d want to see implemented by more companies. Only one type of Samsung smartphone has repair mode at the moment, and it’s limited to the Korean market. However, Samsung claims it will expand repair mode’s availability in the future.
