While testing contactless employee badges, a technician notices that his Android smartphone no longer reacts when placed against the NFC reader. The device still connects to Wi-Fi and streams music over Bluetooth, and a restart did not help. Co-workers' phones read the same badges without issue. Which phone setting is the MOST likely reason this NFC function is failing?
The screen timeout is set to a short duration.
USB debugging is enabled in developer options.
The NFC radio is disabled in the phone's connection settings.
On most Android devices, the NFC radio can be individually enabled or disabled through the "Connections" or "Connected devices" menu. If that toggle is off, NFC tags and readers will not be detected, even though Wi-Fi and Bluetooth radios remain operational. Wi-Fi band selection, USB debugging, and display timeout settings have no impact on NFC hardware and would not prevent tag detection.
