Fix Samsung Galaxy S6 File Sharing Problems including Screen Mirroring issues

The Galaxy S6 comes with various file transfer options and tools designed to offer file sharing convenience to end-users. But what if all of a sudden, something goes wrong and the supposedly hassle-free file transfer becomes more troublesome?


This content will help you deal with this situation. Highlighted in this post are pertinent problems relayed to us by some owners of the #GalaxyS6, who are having trouble transferring contents from their phone to other device or vice versa, as well as #screenmirroring concern.

Problem: Connect Galaxy S6 to Windows 7 PC

“I just purchased this phone and want to sync my Windows 7 data on my desktop with the S6, but I do not want to use the cloud for backup up, etc.  I just want it between the phone and the PC.  I cannot find that option on the Samsung website.  Is there a third party app that is good for syncing? Thanks.”

Answer: You need to use a USB cable to directly connect both devices and transfer photos, music, and other files between your Windows 7 computer and smartphone or vice versa. So here’s what you should do:

  • Ensure your phone screen is unlocked.
  • Use the original (OEM) USB cable or other compatible USB cable to connect your phone to the computer.
  • On your phone, swipe down from the top of the screen to open the notification panel.
  • Tap on USB for… notification and then select Transfer Files (MTP).
  • When prompted with the File Transfer screen on your computer, you can start transferring files by dragging and dropping them into a specific location or folder.
  • Once you’re done moving files from or to your computer, eject your phone from the computer.
  • Unplug the USB cable.

If it’s a Windows computer, there’s no need to download a third-party application. All you have to do is connect your phone to the computer/laptop using the bundled micro USB cable and then open Windows Explorer window on the computer. Scroll down to ‘Devices and Drivers’ or ‘Portable Devices’ section and you should see your Galaxy S6 listed. Just double-click the icon and browse to the folder/files you want to open from your phone.

On the other hand, MAC computers would require you to download and install a compatible version of Android File Transfer app.

Problem: Simple Sharing feature not working, ‘failed to upload to server’ error

“I tried to use Simple Sharing and it doesn’t work. So I keep getting an error that says “server error: failed to upload to server” I cannot get rid of this error. Please help. Thank you.”

Answer: Network problems such as slow Internet/data connection due to server overload can prevent you from uploading files. In this case, your only option is to retry file sharing at a later time. Otherwise, you can try these temporary workarounds:

If you’re still getting the same error, please contact your network provider and have them check for any outages affecting network servers in your area.

Problem: Phone not recognized as Media device by Windows 7 PC

“My Galaxy s6 will not be recognized as a media device by my Windows 7 PC. Therefore I am unable to transfer any files, pictures, music from phone to PC or PC to phone. I receive an MTP driver install failure. Please help. I’ve tried everything I know including Samsung online chat, my carrier tech support, and a hundred different Google searches, all to no avail. May have to take my losses and go back to an iPhone…”

Relevant Problem: “Hi, I am hoping you can respond to my email as I have a problem with my Galaxy S6. I wanted to transfer some music and photos from my computer but it cannot detect my phone. It detects my husband’s S5 and my son’s Samsung Ace so is not a cable problem.  I have got the latest version of the Samsung Kies installed on my PC.  I have looked on your troubleshooting pages and found a similar problem whereby I changed the USB debugging mode from on to off.  Although it stated that with debugging mode off, my phone should connect and be detected, this unfortunately is not the case.  I am now at a total loss … Please I need your advice.”

Answer: If you’ve already tried every possible solution, including those that we’ve recommended in our previous posts but still getting the same problem, then you may try this workaround:

  • Open the phone app/dialer.
  • Dial *#0808#
  • If prompted with the USB settings screen, check the MTP or MTP+ADB
  • Click OK.
  • Connect your phone to the computer again.

This has done wonders to some of those who are facing the same issue with their Galaxy S6.

In addition, make sure you have downloaded the necessary USB drivers and install them on your computer. Also check your computer’s settings to ensure Windows automatically detects new hardware attached to it.
