Smart Switch Mobile lets you instantly transfer personal data between devices with ease.


Generally for connection to be successful, place the devices close together (approx 20cm apart), open the application in both devices and tap Send on the old device or Receive on the new device.


Smart Switch Mobile uses High Frequency Audio to establish a connection between devices. Wi-Fi Mac address is transferred using High Frequency Audio via the speaker of old device to microphone of new device. 


As a result, if speaker of old device is covered or blocked by hands or an object, the audio signal required for connection purposes may be affected and is lost. 


If the speaker of old device is on the rear or back side of device, please ensure the speaker is not covered and face the old device’s speaker towards the new devices microphone for connection. 


If you are still having difficulty or are unable to connect between devices / often disconnected via Smart Switch Mobile, please see further advice below: 

1 Try to transfer / use SMART SWITCH for Mobile in a quiet area away from noise
2 Tap Transfer button only on the old device

You may not be able to connect if the application is not open or the button is not tapped on one of the devices, or if a pair of earphones or a Bluetooth headset is connected to the device. 


If you are looking to switch from a non-Samsung device to a supported Samsung device, please use the Smart Switch PC - PC software tool. For more information, please visit
