Hi Droid Guys, 

I seem to be experiencing problems transferring files from and to my phone, Sony Xperia Z. Yesterday it was working fine but today my computer refused to detect it at one instance but then it has detected it again after several tries. Even so, I cannot copy files to my phone. I only wanted to add music tracks to my current collection and copy photos from my phone’s memory to my computer to back them up. These procedures aren’t just possible as of the moment. I would surely appreciate if you could make guide for this problem. I’m sure I’m not the only one having this problem so it may just be worth it. Thank you. 



Troubleshooting USB connectivity does not need expert knowledge. In fact, all you need is basic knowledge on how the USB file transfer works. Here’s the basic process: when you connect your phone to your computer, it would take few seconds for the computer to successfully detect the device. The phone confirms the connection by displaying USB icon on the notification bar. This time, you can copy files from your phone to your computer and vice versa.

Check physical connection. Make sure the USB cable is properly connected to devices on both ends. To double-check the connection, unplug and re-plug the cable.

Check cable condition. If the computer couldn’t detect the phone, you should check the physical condition of the USB cable you’re using. Check for damages or breakages. Above all, make sure you’re using the original cable that came with the phone when you bought it.

Restart computer. It would take just a minute or less to do this. Make sure your phone is NOT connected yet when you do this; it is necessary to refresh your computer’s memory.

Reboot phone. To eliminate the possibility that some things aren’t right in your Xperia Z, take a little time rebooting it.

Change USB connection mode. Now that you’ve rebooted both your phone and computer, try to change the connection mode before plugging in again.

  1. Make sure that your phone is not connected to a USB cable.
  2. From your Home screen, tap Apps.
  3. Find and tap Settings > Xperia > USB Connectivity > USB connection mode.
  4. Tap Mass storage mode (MSC) > OK.
  5. Tap OK.
  6. Connect the phone and computer using the USB cable.

Use popular file transfer tools. There are tools you can use to help you transfer files from your phone to your computer and vice versa. The following are the most recommended tools by Sony.

PC Companion – this is a good application for Windows OS.

Media Go – still for Windows but has a good proven record.

Sony Bridge for Mac – use this if you have problems connecting your phone to your Mac computer.

Media Go and Sony™ Bridge for Mac can determine the best settings for your device and convert and encode your media files for optimal performance before transferring them to your phone or computer.
