Does anyone know how to transfer data from LG v20 to Samsung Galaxy s6 edge plus? I've tried the nfc and beam thing. Didn't work. Tried by using USB cord didn't work. Starting to get irritated
You should be able to do that with the Smart Switch app. Just download on each device and follow the on-screen instructions (you WILL need an OTG USB Cable/adapter if you want to use USB, though).
If you just want to send some files, then select the files/pictures/media/whatever on your V20 and select SHARE, then either via Bluetooth or WiFi Direct (don't forget to set the S6 to be visible to the V20 if they haven't been paired before). If you want to do this over USB, you need the OTB cable/adapter so that the S6 sees the V20 as an external storage device.
The Beam function also works, but you need the S6's NFC to be turned on and Android Beam active in the NFC Settings of your phone (you can long-press the NFC toggle to go to those settings directly).
