Risk level

Low

Usually safe to check without specialist tools.

Urgency

Low

Quick answer

When Smart Switch shows Smart Switch transfer did not complete or The version of the connected device is not supported on your Galaxy Tab or phone, the transfer stopped due to low free storage, corrupted app cache, Wi-Fi proximity drops, or an unsupported OS version.

Safety first

Stop and check this first

  • Do not factory reset or erase your old device until you have verified on your receiving Galaxy Tab that all transferred files open properly and background app installations have completed.
  • Monitor your notifications after closing Smart Switch because app installations continue in the background; also note that account sign-in transfer requires a lock screen enabled on the previous device for at least 24 hours.

Safe checks you can perform

  • Free up storage on both devices and deselect All to transfer content individually
  • Clear Smart Switch cache and data in Settings > Apps and close background apps
  • Check OS compatibility requirements and reinstall Smart Switch if needed
  • Connect via a data-capable USB cable, allow MTP file transfer, and reinstall the PC or Mac device driver

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Contact Samsung Customer Support or submit an inquiry through the Samsung Members app
  • Do not attempt this professional task: Contact the computer manufacturer if another PC works, or visit a Samsung Service Center for tablet hardware checks

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Contact Samsung Customer Support or submit an inquiry through the Samsung Members app

    What they doReach out to Samsung Customer Support via online chat or the Samsung Members app if Smart Switch transfers still fail after clearing cache and testing a USB cable.

  2. Contact the computer manufacturer if another PC works, or visit a Samsung Service Center for tablet hardware checks

    What they doIf Smart Switch works on a second computer, contact the original computer manufacturer; if the Galaxy Tab fails to connect on any computer or cable, visit an authorised Samsung Service Center.

    They must show youtest results showing whether the Galaxy Tab connects on a second computer and with a different USB data cable.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Free up storage on both devices and deselect All to transfer content individually

    No special tools

    Who:
    You, on both devices.
    How:
    Delete unnecessary items on both devices so the estimated size fits the receiving Galaxy Tab's free space, restart Smart Switch, deselect All on the content selection screen, and select categories individually before tapping Transfer.
    Result that matters:
    Keep the transfer size within available storage limits.
    If transferring smaller individual selections completes without interruption:
    the full batch exceeded free storage.
    If the transfer still fails with plenty of free space:
    clear the Smart Switch cache and data next.
    Evidence to keep:
    Estimated total transfer size compared against free storage on the receiving Galaxy Tab.

  2. Clear Smart Switch cache and data in Settings > Apps and close background apps

    No special tools

    Who:
    You, in Settings.
    How:
    Go to Settings > Apps > Smart Switch > Storage, tap Clear cache, and if needed tap Clear data > Delete. Close unnecessary background apps on both devices, keep them close together on the same Wi-Fi network, and restart the transfer.
    Result that matters:
    Remove corrupted residual files and prevent background app interruptions.
    If clearing residual files and keeping both devices close together allows Smart Switch to finish migrating your data:
    app cache or Wi-Fi drop was the cause.
    If wireless transfer continues to fail or displays a version compatibility error:
    verify OS versions and switch to a wired connection.
    Evidence to keep:
    Transfer behaviour after running Clear cache and Clear data in Smart Switch Storage settings.

  3. Check OS compatibility requirements and reinstall Smart Switch if needed

    No special tools

    Who:
    You, on both devices.
    How:
    Verify under Settings > About tablet (or About phone) > Software information that the device runs Android 4.3+ (Android 7.0+ for encrypted data), iOS 5+ (iOS 12+ for Wi-Fi), Windows 10+, or macOS 10.9+ (note that Chromebooks are not compatible). If compatible, uninstall Smart Switch, restart both devices, and reinstall a fresh copy.
    Result that matters:
    Confirm OS compatibility and replace any damaged Smart Switch installation.
    If both devices meet the software requirements and the freshly reinstalled Smart Switch app connects properly:
    app installation glitch resolved.
    If wireless migration still drops or PC recognition fails:
    use a USB data cable and check USB driver settings.
    Evidence to keep:
    OS versions verified on both devices and result after reinstalling Smart Switch.

  4. Connect via a data-capable USB cable, allow MTP file transfer, and reinstall the PC or Mac device driver

    No special tools

    Who:
    You, with a USB cable.
    How:
    Connect with a USB cable that supports data transfer, tap Allow on the MTP prompt, and open Quick settings > USB for file transfer > Transferring files. If Smart Switch on PC or Mac still does not recognize the device, click the three dots in the upper right corner of desktop Smart Switch and select Reinstall device driver > Confirm.
    Result that matters:
    Complete the migration over a wired USB connection or restore computer recognition.
    If the USB cable connection is recognized and the wired transfer completes without interruption:
    wireless interference or missing USB driver was the cause.
    If Smart Switch still fails after trying another USB port, another USB cable, and a different computer:
    contact Samsung Customer Support.
    Evidence to keep:
    MTP prompt response, USB file transfer setting, and result after running Reinstall device driver.

What it means

This error comes from the Samsung Smart Switch migration utility during wireless or USB cable transfers between Android, iOS, Windows, or Mac devices. A failed transfer or a greyed-out app icon on the Home screen alone never proves that your Galaxy Tab storage or USB port is faulty: Samsung documents that app installations continue in the background even after Smart Switch finishes, and most transfer interruptions are resolved by clearing the Smart Switch cache, freeing storage space, or deselecting All to transfer items individually.

Warnings and stop conditions

Symptoms and causes

Probable causes · in order

  • Insufficient free storage space on either the sending or receiving deviceCommon

    A Smart Switch transfer fails when there is not enough free storage on both devices or when the estimated total transfer size exceeds the receiving device's available space.

    Evidence: Smart Switch transfer issues · Wireless transfer fails when using Smart Switch · Problems you may experience when transferring from Android using Smart Switch

  • Corrupted Smart Switch app cache, residual files, or background app interferenceCommon

    Accumulated cache and residual files inside Smart Switch or unnecessary apps running in the background can interrupt data transmission.

    Evidence: Smart Switch transfer issues · Wireless transfer fails when using Smart Switch · Problems you may experience when transferring from Android using Smart Switch

  • Unstable Wi-Fi connection or devices moved too far apart during a wireless transferPossible

    Wireless transfers require both devices to stay in close proximity on a stable Wi-Fi connection throughout the entire migration.

    Evidence: Smart Switch transfer issues · Wireless transfer fails when using Smart Switch · Problems you may experience when transferring from Android using Smart Switch

  • Unsupported OS version or missing USB MTP permission and device driver on PC or MacPossible

    The error 'The version of the connected device is not supported. Please check the software version of your device' occurs when minimum requirements are not met (Android 4.3+, Android 7.0+ for encrypted data, iOS 5+ for cable or iOS 12+ for Wi-Fi, Windows 10+, macOS 10.9+; Chromebooks are not compatible) or when USB file transfer is not enabled.
