You temporarily make your phone visible so a colleague can send a file. Once the transfer finishes, the conversation moves on. That is a good moment to check the discovery setting rather than assuming the transfer itself returned everything to its earlier state.
For example, Apple’s AirDrop guide distinguishes receiving choices such as Contacts Only and Everyone for 10 Minutes, with behaviour that depends on the software version and account state. Other platforms use their own nearby-sharing controls. Follow the current guidance for your device.
Confirm the person and the file
Before accepting a transfer, make sure you were expecting it and confirm the sender through the conversation you are actually having. A displayed device name alone is weak evidence because names can be changed. Check the file type and purpose before opening an unexpected document or link.
Choose the least broad discovery setting that supports the task. If a temporary wider setting is necessary, understand how long it lasts and what it changes. Do not copy a menu path from an older phone without checking the options shown on yours.
Close the loop after sharing
Confirm the intended file arrived, then review receiving visibility again. If you lent the device to someone for setup, also check that the chosen setting fits your own use. A one-time transfer at an event should not quietly define how you share in every public place afterwards.
For sensitive material, consider whether this is the appropriate transfer method under your workplace or personal requirements. Verify the recipient and avoid sending extra files merely because they were selected beside the intended one.
Nearby sharing is convenient because it removes several steps. Keeping a short beginning-and-end routine restores the decisions that still matter: who can discover the device, who is sending, what is being transferred and which setting should remain afterwards. Convenience is most useful when its boundaries are clear.
