# How do I connect my D3S and smartphone via USB instead of Bluetooth®?

## Head to device settings

Navigate to the device settings on the Kromek ID app from the main menu.

Under "Connectivity Settings" you will see "USB Tethering". Enabling this setting means that a phone and D3S can be connected by USB only.

Disabling this setting means that a phone and D3S can be connected by Bluetooth® only.
