Galaxy S3 is unable to transfer files over USB: "USB device not recognized"
I have Galaxy S3 with baseband version I9300XXLFB and I'm having problems when it is connected to the PC. I cannot transfer or retrieve any files or data over USB.
When I plug it in to my PC, it tells me
USB device not recognizedand the S3 does not appear anywhere for me to access it. I've tried different cables and PCs and they all seemed to exhibit the same issue. How can I get this working?
You may need to use Samsung KIES (software for PC), or get your PC to recognize the 'new' "MTP" USB mode.
For anyone having trouble connecting to Windows using USB in MTP mode, make sure you install the Samsung USB Driver for Mobile Phones from Samsung's website. Here's a link for the Verizon model:
Navigate to the
Manuals & Downloadstab, and then below the tabs, click
Software.There you will see the USB driver listed.
I had a similar problem connecting my Galaxy S3. The drivers were not installing properly. There were messages saying the USB device as malfunctioning. Despite being able to charge the phone, it was not being recognised as a mass storage device nor offering me an option on the phone as to what I would like it to connect to the PC as, until I changed my USB cable.
I had read some posts that had suggested this. After trying all the phone and device manager settings from debugging to reinstalling and updating drivers, this is what worked: trying a new USB cable. The drivers installed themselves. Then, I was able to select Use as Media Device from the phone notificaton menu. I double clicked My Computer, and opened Phone to display media. I was also able to select USB tethering from phone settings to allow connection to the internet, which is what kicked this all off in the first place.
Hope this helps some others.
What I also discovered during this process was how to set the phone up as a wi-fi hotspot. I just followed a neat youtube video detailing this, and was able to connect my laptop to the internet while I sorted out the rest of my problem.
I had a similar problem, but with no error message. My computer just did not see my phone even though the computer recognized any other USB device i put in. Note: on a previous session my computer DID recognize my phone and I was able to b/u some files.
My final solution was fairly simple, while the phone was still on I removed the battery from the phone and left it out for 5 minutes. Then I reinstalled the battery and turned the phone on. After plugging the phone into my computer via the USB cord I had a connection phone to computer.
No, I do not have a technical explanation for this.
Have a look to the following Steps
Step 1 # Try cleanup and reinstall of drivers
- Pull the SIM card out and do a factory reset with format
Step 2 # You can to use Samsung KIES (software for PC), or get your PC to recognize the "MTP" USB mode.
- Can I disable MTP mode and just have a regular USB connection?
- Samsung Galaxy S3 not connecting via USB
Step 3 # Make sure you install the Samsung USB Driver for Mobile Phone
Step 4 # For file transfers, you can use Airdroid, which connects through wifi.
Before updating my Galaxy S III to Android 4.3, didn't have any problem with Windows 7. It's obvious that W7 should have recognized it even if Kies software were not installed. That was with main before updating to new android. But saddlery W7 was not able to find the Galaxy SIII in Media device (MTP) mode!
Solution for me:
