This tutorial will explain you how to connect your Micro-SD card from your smartphone to your PC/laptop.
Connect the USB cable to the smartphone and to the PC/laptop.
From the smartphone, go to settings, applications, development, check “usb debugging” once, click ok,
wait around 3 seconds, uncheck “usb debugging”.
At this point, you should see the green Android robot and a button “Turn on USB storage”.
Click on it, ok.
Wait around 10 seconds. The PC should pop a window so you can open the SD-card storage.
This method works only if you want to browse the content of your SD-card, not the internal storage of your device.
