Re: my phone is not connecting to my laptop
Check to make sure you are using a Usb 3.0 port my Lumia 1020 had the same issue on all recent builds of w10mobile preview, my solution was to go to device manager or control panel if it is not coming up in device manager and go.to it's properties tab and uninstall the driver,unplug the phone from the usb, then plug it back in usb port and let it reinstall driver and if it does not pick it up when you plug it back after uninstalling the driver try soft reset as well that always works for my Asus notebook, last resort if all of these fail(mine did)you can hard reset, don't sign in and once your back at home screen you can go sign in and your pc will definitely recognize it as a windows phone Usb device. Only thing is hard reset erases data but I always back mine up so no issues for me.
