Turn Android Beam On or Off auf Samsung
Android Beam lets you share websites, contacts, and files between two NFC-enabled devices by holding them back to back. If the option is missing from your share menu, the feature is usually turned off inside the NFC settings, or the device simply lacks an NFC chip.
To check or change the setting, go to Open the Settings ➔ Tap on Connections ➔ Tap on NFC and payment ➔ Enable or disable Android Beam. The toggle only appears if NFC itself is switched on, since Android Beam depends on that radio being active.
Turning Android Beam off does not affect other NFC functions like contactless payments or pairing accessories. It only blocks the direct file-transfer handshake between two devices touched together.
If your Samsung device runs a newer version of the software, Android Beam may already be replaced by a different nearby-sharing feature. In that case, look for a sharing option with a similar name instead of searching for Android Beam specifically.
Battery cases, thick covers, or metal backplates can also block the NFC signal even when Android Beam is enabled, which looks the same as the feature being switched off.
