@risottobias Repair mode is a guest user account to let the repair technician verify your phone works without having access to your data. It does not impact normal File Based Encryption, etc.

> This feature simulates a factory reset (but doesn't actually wipe your phone) so you can send your phone in for repair and the technicians won't have access to any of your personal data while they troubleshoot and test your device. Once your phone is returned to you, you can exit repair mode by entering your device's PIN/pattern/password, which restores your device to normal.
I actually did a ghetto version of this by temporarily booting a GSI image as a "factory reset" of my phone to prove to support my camera issue was a real hardware issue, without having to actually factory reset (I still did after repair was approved because I wanted to relock my bootloader before handing it in to support).
