Urgency

Quick answer
When a Samsung Galaxy Tab or phone displays Software update failed or stops mid-update, the most common causes are insufficient internal storage, an unstable Wi-Fi connection, low battery charge, or an interrupted download that needs Smart Switch on a PC.
Safety first
Stop and check this first
- Do not disconnect the USB cable or turn off the tablet while Smart Switch is installing a system update, as interrupting firmware writing can leave the device unable to boot without service reflashing.
Safe checks you can perform
- Free up the required storage space by uninstalling unused apps
- Connect to a stable Wi-Fi network, charge the battery, and check Software information
- Install the software update via Smart Switch on a PC with USB set to Transferring files
- Restart the PC, reinstall Smart Switch, and test a different USB cable or port
Leave these tasks to a qualified professional
- Do not attempt this professional task: Contact Samsung Support via online chat or Samsung Members for update help
- Do not attempt this professional task: Request authorised Samsung service to reflash the device if it fails to boot normally

Free up the required storage space by uninstalling unused apps
- Who:
- You, in Settings.
- How:
- Check the amount of storage space requested by the error message, open Settings > Apps, select an app you no longer use, tap Uninstall, and tap OK to confirm.
- Result that matters:
- Ensure available storage exceeds the space required by the software update.
- If available storage exceeds the required amount and the software update resumes from the notification:
- low storage was the cause.
- If storage space is sufficient but the update still fails:
- check your Wi-Fi stability and battery level next.
- Evidence to keep:
- Amount of storage space requested on screen and free space remaining after uninstalling unused apps.

What it means
This message is generated by the system firmware updater under Settings > Software update when a package cannot finish downloading or installing. Seeing Software update failed on its own never proves that your tablet's internal flash storage or hardware is defective: Samsung notes that in most cases the device recovers from the error and tries again once you free the required storage space shown on screen, stabilize your Wi-Fi connection, or apply the update over USB using Smart Switch on a computer.
