After checking you have used the Samsung Smart Switch correctly, try the solutions below to fix Samsung Smart Switch stuck at 99% problem:

Solution 1: Make Sure the USB Cable and Port Are Workable

If you're using wireless transfer, consider switching to a wired connection. A USB-C cable provides a more stable and faster transfer process.

Check whether there is any damage of your USB cable, USB port, or USB adapter. To do so, you can try the USB cable you are using on other devices or use another workable USB cable to connect your phones. Besides, check if there is dirt in the USB port of your phone, use a dry cloth to clean it.

Solution 2: Check for Stable Internet Connection

A weak Wi-Fi signal can cause Smart Switch to freeze or get stuck, especially when transferring large files. Make sure both devices are connected to a stable, strong Wi-Fi network:

• Use a secure, private Wi-Fi connection.
• Try placing both devices closer to the Wi-Fi router.
• Restart the Wi-Fi connection. To do this, you can navigate to Setting > Wi-Fi and restart it. Or you can simply drag down the notification panel to re-enable the Wi-Fi.

Solution 3: Charge Your Phones

To ensure a Samsung Smart Switch works smoothly, you should make sure your phones have enough battery to carry out the data transfer. If you are using Wi-Fi transfer mode, you can charge the devices during the transfer so that the Smart Switch backup stuck problem won't happen due to low battery.

Solution 4: Free Up Space on Your Target Device

Smart Switch may get stuck if there's not enough storage on the device you're transferring data to. Freeing up storage can resolve this:

1. Check your target device's available storage in Settings > Storage.
2. If there is not enough space on your device, you can delete unnecessary apps, files, and media to create sufficient space.

Note that to transfer data successfully, both devices should have at least 500 MB free space in their internal storage.

Solution 5: Don't transfer all the data at once

Try not to transfer the overall data at once. Data like apps have large size often take a long time to transfer. When transferring data, you can transfer one type of data at a time. And if it is because of the corrupted data that lead to Samsung Smart Switch stuck, you can find out which data is the cause by transferring them bit by bit.

Solution 6: Clear Cache and Data of Smart Switch

If the Samsung Smart Switch is taking a long time to transfer, you can try to clear the app's cache and residual files on both your devices. This should fix most Samsung Smart Switch stuck problems. To do this:

1. Go to Settings > Apps, select Smart Switch, and choose Storage.
2. Tap Clear Cache and Clear Data to reset the app.
3. Restart the app and try the transfer again.

Solution 7: Update the Smart Switch App and Device Software

Outdated versions of Smart Switch or device firmware can lead to compatibility issues and performance hiccups. Updating both often resolves freezing issues.

1. Go to the Samsung Galaxy Store or Google Play Store and update the Smart Switch app.
2. For system updates, go to Settings > Software Update and install any available updates on both devices.

Solution 8: Restart Both Devices

If Samsung Smart Switch stuck at 99% issue still persists after trying all the solutions above, then you can restart your phones. Make sure to disconnect your phones before restarting them.

Solution 9. Close Background Apps

Running apps in the background can cause conflicts and reduce device performance, affecting Smart Switch:

1. Close all open apps on both devices before starting the transfer.
2. This frees up memory and processing power, which Smart Switch needs to run smoothly.
