Getting your Android phone repaired? Turn on this setting first - and lock down your data

### Executive summary This ZDNet article explains Android's Repair Mode (Maintenance Mode on Samsung) — a feature that creates a temporary, sandboxed profile so technicians can use a device without accessing user apps or data. It notes requirements (Android 14 on Pixel/Samsung, ~2GB free), provides setup and exit steps, and shares an anecdote where Repair Mode revealed a SIM card unseen by the normal OS after an update, highlighting the feature's usefulness when handing a phone for repair.
