Resetting your phone before bringing it in for repair is a normal procedure to prevent any chance of private information (like images or accounts) falling into the wrong hands . The need to back up your data beforehand and restore it later adds to the hassle of getting your device fixed.
Sometimes people find this not very convincing and either wipe the device completely or give it for repair with their personal data, which often results in data leaks. To get rid of this hassle and privacy and security concerns, Samsung came up with a solution called Repair Mode .
This new feature will be available in the Battery & Device Care section of the Settings menu. Enabling it reboots your device. When enabled, the mod hides all personal information including pictures, texts, accounts and even apps (only default installed apps are active). In essence, the phone appears to have been reset.
Once the repairs are complete and you pick up your phone, you can use fingerprint or pattern lock to turn off Repair Mode . This will reboot the phone once again but this time all your data will be fully accessible . All changes made by the technician during the repair will also be undone.
Galaxy S21 series will first have Repair Mode via a software update . According to Samsung, it will “expand it to a few additional models in the future.” However, since the press release was only posted on Samsung’s Korean site, it appears that the feature may initially be exclusive to South Korea.
