I connected my Samsung phone to my windows 10 pro pc to transfer files --does not show any connections on desktop--can't open--went to devices and printers--doesn't show the connected device--windows 7 did show all I connected--what am I missing.
You might have to enter Disk Management and locate the missing phone. It might not have a drive letter assigned and can't be found. This article goes into more details. (Hint: to save some typing you can right click the start button and access Disk Management from there.)
