Why Is Samsung Smart Switch Stuck at 99 Percent?

Samsung Smart Switch getting stuck at 99% during a data transfer can be frustrating. Several common reasons can explain this issue:

How to Fix Samsung Smart Switch Stuck at 99%

The section below lists all the possible ways to fix Smart Switch stuck at 0, 5, and 99%. However, if you are eager to migrate your data to the new Samsung phone, there is a Smart Switch alternative that can move photos, videos, contacts, and more from Android/iPhone to your Samsung.

Fix 1. Check the USB Cable and Port

Faulty cables or improper USB ports can disrupt the data flow. It leads to the Smart Switch freezing at the final stage of the transfer process. Ensure that cable and port are in optimal condition. Users can mitigate such issues and complete their data transfers without interruptions.

  • Examine the USB cable. Look for any visible signs of damage along its length. If there's anything wrong, replace it. Use a cable that is compatible with both devices and supports data transfer at the required speed.
  • Inspect the USB ports. Ensure there are no physical obstructions to prevent a secure connection. Blow gently into the ports to remove any dust or debris causing connectivity issues.


Fix 2. Charge Both Your Devices

Ensuring that both the source and destination devices are adequately charged is essential. Insufficient battery levels can lead to instability in data transfer processes. This scenario is particularly common when transferring large amounts of data or during extended transfer sessions. Charge both devices to sufficient levels to ensure a stable power supply throughout the transfer. It is suggested to have at least 50% of battery.


Fix 3. Clear Smart Switch Cache

Clearing the cache of the Samsung Smart Switch helps you resolve the issue. The cache of the Smart Switch app can accumulate temporary data and files that may become corrupted. It can cause performance issues such as freezing during data transfers. Users can effectively refresh the app's temporary files and settings by clearing caches. It helps in ensuring that the Smart Switch operates smoothly and completes data transfers without interruptions.

Step 1. Open Settings on your Samsung device. Select "Apps." Click on "Smart Switch".

Step 2. Tap on options like "Storage" or "Storage & cache." Tap on the "Clear Cache" button to clear the Smart Switch app's cache.


Fix 4. Free Up Space of Target Phone

Ensure that the target phone where the data is being transferred has sufficient storage space. Insufficient storage can hinder the data transfer, which is common when transferring large amounts of data. Freeing up space ensures that there is enough room for the incoming data, helping in an uninterrupted transfer process.

Step 1. Open the "Storage." Identify and uninstall any apps that are no longer needed or rarely used.

Step 2. Go to "Apps." Select apps that are consuming a large amount of storage.

Step 3. Review and delete unnecessary data on the target phone.


Fix 5. Restart Wi-Fi

If you use the Smart Switch to transfer data wirelessly over Wi-Fi, Wi-Fi connectivity issues can disrupt the seamless data transfer. It can cause the Smart Switch to freeze just before completion. Establish a stable connection to potentially resolve the underlying cause of the Smart Switch stuck. Users can refresh the network settings by restarting the Wi-Fi connection: Go to Settings > Wi-Fi. Turn off Wi-Fi and enable it again a while later.

Fix 6. Restart Your Devices

Temporary software glitches or software conflicts can also cause the issue. Restart the source and destination devices to refresh the system and clear temporary data. This can quickly restore normal functionality to the data transfer process and ensure a seamless experience when migrating data between Samsung devices.

Step 1. Power off both the source and destination devices.

Step 2. Select "Power off" or "Restart". Wait for a few seconds. This allows any residual power to dissipate and ensures a clean restart.


Fix 7. Reinstall Smart Switch

The problem may be due to corrupted installation files or outdated software. Make sure to have the latest version of the application. It potentially fixes bugs or compatibility issues that could be causing the transfer to freeze. Reinstalling Smart Switch provides a fresh start and eliminate potential software conflicts and allowing for a smoother data migration experience.

Step 1. Open Settings > Apps > Samsung Smart Switch. Select to uninstall the app.

Step 2. Restart both the source and destination devices.

Step 3. Download and install the latest Samsung Smart Switch app version.


Fix 8. Perform Software Update

Software update on your Samsung device can resolve the issue. It includes bug fixes and improvements to system stability. Update the device's operating system to ensure that it has the latest fixes. It is particularly effective if the freezing issue persists despite restarting devices.

Step 1. Connect to a strong Wi-Fi network.

Step 2. Open Settings > Software Update > Download and install.


Step 3. When it finishes updating, open the Samsung Smart Switch and initiate the data transfer again.

Fix 9. Do Not Transfer All Data at Once

One effective troubleshooting method is to avoid transferring all data at once. This problem often occurs when attempting to transfer a large amount of data in a single session. The system's resources can cause the transfer process to freeze before completion. This method is useful where network or device resources may be limited. It ensures that each segment of data can be transferred successfully without encountering the 99% freeze issue.
