Sending your phone in for repair without resetting it carries a certain amount of risk. What if a technician digs through your personal files and photos without your permission? Even if there are no compromising media files on your phone, the potential loss of privacy is excruciating. Directly addressing this fear, Samsung introduces Repair Mode to take the worry of handing your phone over to a service centre away.

Repair mode, as it sounds. Users can enable a temporary state while their phone is under repair. This option will temporarily hide all personal files, applications and information. At first glance, the phone will appear as if it has been completely reset. In this state, technicians can still perform their duties, but they lose access to your information.
After repairing, users can disable the mode by unlocking with a fingerprint or a graphic key. The system will reboot and restore your files after disconnection.
Users will also have the ability to log recent issues and actions (without personal information) before activating repair mode. This is an option, of course. Repair mode can be enabled without logs enabled.
Nowadays, resetting your phone before handing it over to an authorized service center is already a standard procedure. In fact, it’s not the only way to repair the phone.
Although it is still better to have the devices officially repaired, people will still go to unofficial professionals for repairs. Usually, these places do not require you to reboot the phone. The repair mode should provide the same level of security, preventing intrusions.
Right now, Samsung is first releasing this update for the Galaxy S21 series with plans to expand in the near future.
