How to Fix Samsung Smart Switch Stuck?

Before moving to the possible fixes, make sure you are using the Samsung Smart Switch app correctly. For this, you can look at Samsung’s instructions for using the app. Then try the following fixes to resolve the Smart Switch stuck at 99% problem.

Fix 1. Change the USB Cable and Port

Most basically, make sure your USB cable, adapter, or connecting ports are not damaged. To do so, you can take the following measures.

• Unplug Your Phones: unplug the devices, close Smart Switch on both phones, and try again. Meanwhile, try swapping the ends of the cable when you re-plug in the devices.
• Connect Different Devices: Next, plug in other phones or devices to check if they work with the same USB cable and adapter.
• Clean the USB Port: If the other phones are working fine, clean your phone’s USB port to get rid of any dirt or debris.

Replace the USB cable with a new one if it doesn’t work at all. Try again and see if your Smart Switch transfers data normally.

Fix 2. Charge Your Devices

Ensure that both devices are charged with a high battery so that it will slim down the possibility of powering off or getting stuck at a certain percentage. A wired connection will help to charge when migrating files. If you use the Wi-Fi transfer mode, you can conveniently charge your devices during the process.

Fix 3. Connect to A Stable Network

Switch from a USB cable connection to a wireless one or vice versa. Since Samsung Smart Switch supports both wired or WiFi connections, you can make an exchange if the present connection causes you stuck at 99%. It works for some people who have canceled the transfer with the cable and chose the wireless transfer method instead.

Fix 4. Free up Space on Samsung

You may dismiss how much storage is left on the target Samsung phone while the transferring data needs more space than existing. If this is the case, try to free up some storage on your Samsung phone so that it can undertake the full data, or insert an SD card to save more files.

To free up space on Samsung:

Step 1: Go to your device’s Settings and select the Battery and Device Care option.

Step 2: Now, tap on the Storage option to open the Internal storage of your device.

Step 3: In the internal storage, you can check where most storage is used and delete the specific files.

Fix 5. Don’t Transfer All Data at One Time

“I find it’s the text messages that take longest. If you choose to transfer like 50k text messages it tends to freeze on it”. A user posted on Reddit.

Smart Switch data migration stuck at 99% can also be solved by migrating each type separately. Partly transferring files will not only increase the speed but also give you a chance to know which file might be the culprit. Besides, it makes it possible to transfer important data only if you don’t have enough space on Samsung phone too.

Fix 6. Clear Cache on Smart Switch App

If all else fails, the issue might be with the Samsung Smart Switch app and has nothing to do with your phone. If the Smart Switch is taking forever to transfer data or is stuck at one point, try clearing Samsung app cache and residual files. Make sure to do it on both the source and target phone.

To do this, you can take the following steps.

Step 1: Tap the Settings of your device and navigate to Apps.

Step 2: Now, find and tap Smart Switch.

Step 3: Next, tap on Storage and select Clear cache.

Note: Alternatively, you can clear the app’s data by tapping Clear data.

After you have taken the above steps, you can restart the data transfer and check if the Samsung Smart Switch stuck problem has been fixed.

Fix 7. Reinstall the Samsung Smart Switch

Sometimes, an app installed incorrectly can cause malfunction during operation. As it’s hard to decide which components are missing or corrupted, the better choice is to reinstall Smart Switch app on your phone.

Go to Settings > Apps. Then, find Smart Switch and uninstall it before downloading it again from the Google Play Store. Make sure that you repeat this process for both devices.

Fix 8. Update Device Systems

Samsung Smart Switch works on Android 4.3 or iOS 4.2.1 or later. The target new phone is not likely to fall into system incompatibility while your source device may be too old to use Smart Switch. Make sure both phones are using proper system versions. Upgrade to a supported version if one of them is running a system below the requirements.

To do this, you can take the following steps.

Step 1: Go to your phone’s Settings. You can pull down the notification panel to click on the settings icon.

Step 2: Next, select Software Update.

Step 3: Now, tap the Download and install the available updates.
