When your Samsung Galaxy S26+ doesn't show up on your PC, it can stop you from transferring photos or backing up files. Connection problems can have several causes, and the checks below can help you get connected.
The quickest fix is often the cable or the port. Grab a different USB-C cable, preferably one that supports data transfer, and try a different port on your computer. If that doesn't work, a simple restart of both your phone and PC can clear out any temporary software glitches causing the handshake to fail.
Check Your USB Connection Mode
Unlock your S26+ and connect it to your PC with a USB data cable. If the "Allow access to phone data" prompt appears, tap Allow. Pull down your notification shade and tap the USB connection notification to check how the connection is being used.
Select Transferring files or Transferring files / Android Auto. If you don't see the notification at all, first enable Developer options (open Settings > About phone > Software information and tap Build number seven times), then go to Settings > Developer options > Default USB configuration. From there, you can set the default USB configuration to "File Transfer."
Inspect and Clean the USB-C Port
Check the USB-C port for moisture or debris before trying another connection. First, power off your phone and take a close look at the USB-C port with a flashlight. Lint and pocket debris are common culprits.
Use a dry, soft-bristled brush to gently remove loose dust. Avoid using metal objects or liquids in the port. Once you've checked and cleaned the port, reconnect the cable and see whether your PC recognizes the phone.
Update Your Windows USB Drivers
Windows might not have the right driver for your new phone. Connect your S26+ to your PC, then press the Windows key + X and select Device Manager. Look under "Portable Devices" or "Other Devices" for your phone, which might have a yellow exclamation mark.
Right-click on the device and select "Update driver." Choose the automatic driver search option. For the most reliable result, I'd download the official Samsung Android USB Driver from Samsung's developer site and install it manually.
Install the Latest One UI Update
Software updates can help address bugs, so check whether an update is available for your phone. On your S26+, go to Settings > Software update and tap Check for updates, or Download and install if that is the label shown.
Make sure your phone is connected to Wi-Fi and has sufficient battery. Follow the on-screen instructions to install any available update, then try the USB connection again.
Try a Different Computer or Cable
This is a crucial isolation step. Try connecting your S26+ to a different computer, if possible. If it works there, your primary PC's settings or USB ports may be the cause.
Similarly, not all USB-C cables are created equal. Some are charge-only. Use the cable that came with your phone, or ensure you're using a high-quality cable certified for data transfer. The included USB Type-C cable can be used to connect your phone to a computer.
Enable Developer Options and USB Debugging
Developer options include additional USB settings you can check. First, enable Developer Options by going to Settings > About phone and tapping "Software information." Tap Build number seven times until you see a message saying you're a developer.
Go back to the main Settings menu, find and open Developer options, and then toggle on USB debugging. Confirm the prompt on your screen. Now try connecting to your PC again.
Check Your PC's Antivirus or Security Suite
Sometimes, overzealous security software can block new devices. Try temporarily disabling your antivirus or firewall software on your Windows PC to see if that's the barrier.
Remember to only do this for a moment to test the connection, and be sure to re-enable your protection immediately afterward. Check for a security alert identifying a blocked connection before changing additional settings.
Use Samsung's Smart Switch for PC
If standard file transfer isn't working, Smart Switch is another option for backing up your files. Download and install Samsung Smart Switch on your Windows computer from Samsung's website.
Open Smart Switch on your PC, then connect your S26+ via USB. If the phone isn't recognized, check that the latest USB driver is installed correctly on your PC, then reconnect it. It's a great tool for transfers anyway.
Check File Access on Your PC
Once you've allowed access on your phone and selected Transferring files, open File Explorer on your PC. Select your phone's name in the side menu to browse its files.
Open the folder containing the files you want to transfer, then drag and drop them onto your computer. You can also copy files from your computer into the phone's storage.
