A day looking for a solution of the same problem like you.
I use a Sony C4 and Android Studio on Windows 10, 
my problem of my phone is not detected in Windows 10.
You can check in MyComputer> Properties> Device Manager.
The first step
- I downloaded OEM USB Drivers for my phone, see the list of OEM Drivers url
 
- create a directory "usb_driver" in <.sdk.>\extras\google\
 
<.sdk.> = C:\Users\Karebet\AppData\Local\Android\SDK\
- I extract OEM USB Drivers then copy paste to <.sdk.>\extras\google\usb_driver\
 
The second step
- I not download from the SDK but from Google USB Driver
 
- I extract the Google USB Drivers then copy paste to <.sdk.>\extras\google\usb_driver\
 
not include directory "amd64" and "i386"
Third step
- Right-click MyComputer> Properties> Device Manager
 
- check whether there is a device not in the know in Others Device
 
if there: right-click> Properties> Tab "Driver"> Update Driver> Browser my computer blabla > select dir usb_driver in <.sdk.>\extras\google\, 
and click OK . wait a while Driver has been detected
Hope it helps you
