So, your Samsung Galaxy S4 won’t connect to your PC? There are a few common issues people run into when trying to get their S4 to show up as an MTP device. Here are a couple of them.
If you’re using Windows, ensure that you have downloaded and installed the correct drivers properly. Search Samsung’s Support site for your device and make sure you are installing the right drivers for your particular version of the Galaxy phone.
If you have installed drivers that may not be the correct drivers for your device, you’ll want to uninstall them from Control Panel > Programs before installing the correct drivers.
Another reason your PC won’t detect the Galaxy S4 might be the cable. Some users have reported that there just is something different about the cable that’s included with the Galaxy devices. Using a cable from other phones often doesn’t work. This was the problem in my case. The device would get detected by Windows 8, but showed under “Unspecified” section as a “SAMSUNG_Android” device and would never show under the Portable Devices section of Computer. Once I tried the white cable included with the S4, Windows detected it just fine.
Do you have other problems besides drivers or cables causing your issue? Please share your experience in the comments section.
