Galaxy S3 Not Detected by Windows XP, 7 and 8 Computers


This is one of the emails we received from our readers. Basically, the owner cannot transfer files from the Galaxy S3 to his computers, and vice-versa, because the phone cannot be detected properly. The following is the actual email from the reader:

Long story short, I’m ongoingly having difficulties with connecting / synching my GS3 to my laptop (running XP) and my home desktop running Win 8. With and without Kies I might add and when it happens the only thing that I can do is charge my smartphone.

Typically I start troubleshooting by googling for solutions, and after about an hour (each time) I eventually connect and am able to upload or download files. Very frustrating, and I’m truly starting to think that these issues only started happening after I updated my device to Jelly bean 4.1.1 am I missing something obvious here… PLEASE HELP !!

There are actually two things you can do to make sure your Galaxy S3 will be detected properly in Windows-operated computers. First, is to install the Samsung KIES. The application comes packed with all necessary drivers for Samsung devices to get detected each time they are plugged in. The fact is, at least, 90 percent of Samsung smartphone owners have already installed it and many reported to have experienced this problem after an update.

Samsung didn’t provide information whether there are compatibility issues but users said that problem would go away if the KIES is uninstalled completely from the system and reinstalled. It’s worth the time to do this procedure, although it’s not a guarantee that the problem will be solved.

But as far as establishing a connection between the phone and the computer is concerned, all you need are drivers. Aside from the KIES application, Samsung also offers driver packs. After doing the procedure above and the problem continues, try this:

Step 1: Download necessary drivers for your device. For owners in the U.S. who are under any network, the following are direct links to drivers’ download page.

Note: For owners outside the US and those who are using S3 with models other than the ones mentioned above should go here [direct link] to download drivers for your device. But first you have to know the model number of your phone by going to Settings => About phone.

Step 2: In your PC, go to the desktop, right-click on Computer and choose Properties. A new window will pop up. In the upper left-corner of that window you can find a link that says Device Manager, click on it.

Step 3: A new window will pop up listing all devices in your computer. Scroll down to and expand contents of Universal Serial Bus controllers and find the ones with exclamation point (!).

Step 4: Right-click on the device with exclamation point and choose Update Driver Software => Browse my computer for driver software.

Step 5: Browse through the directory where you’ve downloaded the driver pack a while ago.

Step 6: Click Next. Your computer will automatically search for right drivers and install them.
Let us know if this works.
