Just switched from Android to the Lumia Icon and my surface at first recognized my phone but it won't show up in the file manager now. Any idea what I could do?
Restart your Surface, and uninstall the drivers for your Lumia. Check if it allows a USB data connection, too. And, you should also reboot your phone as well, just in case it's a problem with the Icon.
Also, in case other people run into this problem and don't have a fix...
I learned the hard way... Not all microUSB-to-USB cables can transfer data. I thought all the cables were the same. But some of those cables are only good for charging. And the Nokia documents back that up. I didn't believe it until I tried it. With some of my cables, my phone would not be recognized at all.
