What is Samsung accessory service

The notification of “Transferring file, please wait” became an issue because of the app’s new update. This notification usually appears on Galaxy devices: S7, S8, S9, etc. When this notification appears occasionally then it is not a problem because the app sends and receives data. You may also get this notification after you end a phone call. This is because the app is registering the call history if your watch is connected to a smartphone.


If you want to stop this notification from showing up again and again. Then try re-installing the Galaxy Wearable app. Because of this the plug-in and the accessory service app will be reinstalled too. As a result, it will install all the files correctly and then the notification of file transferring will stop.

Settings > Apps > Samsung Accessory Service > Force stop. 

Lastly, you can try to unpair the watch and then repair it with your smartphone. After doing so, restart your phone.
