You are connecting your Android device to Windows PC for file transfer purpose. You select the MTP mode on Android phone(or tablet) but do not see your device storage in the explorer window. Next, you head toward Device Manager and see that there is a yellow exclamation mark in front of MTP USB Device under Portable devices.

You can choose the option of automatically install the driver from the Internet.

Here is the screenshot of the error while trying to install the MTP device driver.
