I need to leave my phone at a repair shop. The reparation is not trivial, so I can't expect them to do it under my eyes while I wait.
But my phone is all my life. Like for most of us (I guess), I have personnal information, pictures, conversations that I would not like being seen by a stranger. Considering they don't need to unlock it to repair it, how can I make sure they don't access sensitive data, without wiping clear my device (which would be a pain to restore)?
The only things I thought about:
- removing SD card
- setting a (strong) PIN code
- encrypt the internal memory
My phone is a Samsung A5 2017. I'm not even sure I can fully encrypt the internal memory - a quick search seems to indicate that I can't -, so I'm quite at a loss.
