How to Fix Xperia Companion Not Detecting Phone? 12 Trusted Solutions

An Xperia phone that works normally can still fail to connect with a computer through Sony's software. This guide covers practical ways to fix Xperia Companion not detecting phone and offers other software for backing up, transferring, or managing Xperia data if Xperia Companion cannot detect the device.

Whether the problem comes from the connection, software, or device settings, the following methods can help you get Xperia data management back on track.

Part 1: A Quick Fix to Xperia Companion Not Detecting Phone

When you want to troubleshoot this quickly, try these five steps first:

• Unlock the Xperia.
• Connect it with a data-capable USB cable.
• Select File Transfer (MTP) from the USB notification.
• Try another USB port without a hub.
• Update/reinstall Xperia Companion.

Assuming your goal is to use Xperia Companion's Software Repair, the procedure is different:

Part 2: Other 11 Fixes to Xperia Companion Not Detecting Phone

Fix 1. Unlock the Xperia and select File Transfer

Connect the phone to the computer, unlock the screen, then swipe down the notification panel. Tap USB charging/Charging this device via USB and select File Transfer/Transfer files (MTP) instead of charging only. This is particularly important because the default USB mode is generally charging.

Fix 2. Try another USB cable

Some USB cables are intended only for charging and cannot transfer data. Use the original Sony cable or a known data-capable USB cable. Also try another USB port directly on the computer. Avoid USB hubs, docks, and extension cables while troubleshooting.

Fix 3. Check the Xperia USB port

Dust, lint, or moisture in the USB-C port can interfere with detection. Make sure the port is clean and completely dry before reconnecting the phone. Sony specifically warns that moisture can disable USB detection on some Xperia models.

Fix 4. Restart both devices

Disconnect the Xperia, restart both the phone and computer, then open Xperia Companion and reconnect the phone. Sony recommends checking whether the issue is resolved after each troubleshooting step.

Fix 5. Reinstall Xperia Companion

Make sure you're using the latest Xperia Companion. Sony says versions older than 24.9.1.202408201019 are no longer supported and won't automatically update, so older installations should be uninstalled and replaced with the latest version.

Download Xperia Companion from Sony Support.

Fix 6. Check the Windows MTP driver

If Windows itself doesn't recognize the Xperia, the MTP USB driver may not have loaded correctly. Open Device Manager → Portable Devices, locate the Xperia device, choose Update driver, and select MTP USB Device when available.

Fix 7. Windows N/KN users: Install Media Feature Pack

If you're running Windows 10/11 N or KN, MTP file transfer may not work without Microsoft's Media Feature Pack. Sony specifically recommends installing it for these Windows editions.

Fix 8. Try another computer

Connect the Xperia to another Windows PC or Mac. If it works there, the problem is more likely related to the original computer's USB port, driver, security software, or Xperia Companion installation rather than the phone itself. Sony also recommends trying another computer when USB detection fails.

Fix 9. Temporarily disable antivirus or firewall

Security software can sometimes interfere with the connection. Temporarily disable third-party antivirus/firewall software and reconnect the phone. Re-enable it afterward if it isn't the cause.

Fix 10. Clear Media Storage data

If the Xperia still isn't detected, Sony recommends clearing the Media Storage system app's data on supported Android versions, then restarting the phone. This does not delete your photos, music, or other media, although related information such as playlists may be affected.

Fix 11. Update the Xperia software

Check Settings → System → Software update and install any available update. Sony recommends keeping the Xperia software up to date when troubleshooting computer-connection problems.
