Some devices running Android Lollipop (5.1.1) have additional settings to control what devices can connect via USB - which BlueShot uses. Here is an example on a Sony Z5 running Android 5.1.1




Select Device Connection




Select USB Connectivity




Select Detect USB Device

Ensure BlueShot is plugged in and select USB device.
Your phone should now correctly recognise BlueShot.

Please  if you wish to check that your phone is compatible with BlueShot. Thanks.
