Insufficient storage is a primary reason for update failures. Your Galaxy S25 Ultra, like any other device, requires sufficient free space to download and install updates. To free up storage, you can:

• Uninstall unused apps: Navigate to Settings > Apps. Read the list and uninstall applications you no longer use.

• Clear cache: Go to Settings > Device Care > Storage > Clean Now. This removes temporary files that might be occupying valuable space.

With ample storage, you create an environment in your phone for updates to install smoothly.

Sometimes, a simple restart works wonders. Restarting your S25 Ultra can resolve minor system glitches that might be preventing an update. To do this:

Step 1: Press and hold the Power button and Volume Down button simultaneously.

Step 2: Tap Restart.

Step 3: Confirm action.

Once your device restarts, attempt the software update process again.

The Settings app itself may encounter temporary issues. Closing and reopening it can refresh its processes. Here’s how to do it:

Step 1: Open the recent apps screen by swiping up from the bottom of the screen and pausing in the middle.

Step 2: Swipe the Settings app away to close it.

Step 3: Reopen the Settings app and navigate to Software Update to retry the installation.

Conflicting settings can interfere with the update process. Resetting all settings to their defaults can eliminate these errors. To proceed:

• Navigate to Settings > General Management > Reset > Reset all settings.

• Confirm your choice and wait for the process to complete.

After the reset, reconfigure your preferences and attempt the update again.

If over-the-air updates continue to fail, Samsung’s Smart Switch is an alternative method. This tool will allow manual software updates done via computer. To use the Smart Switch tool:

Step 1: Download and install Smart Switch on your computer from Samsung's official website.

Step 2: Connect your Galaxy S25 Ultra to the computer using a USB cable.

Step 3: Open Smart Switch; if an update is available, you'll be prompted to install it.

Step 4: Follow the on-screen instructions to complete the update.

This alternative method bypasses potential issues with the Galaxy S25 Ultra’s internal update mechanism.

If you’ve tried the basic troubleshooting steps but your Galaxy S25 Ultra still won’t update, don’t worry, there are other possible fixes to explore. Let’s cover some alternative methods that can help you get past the “couldn’t update” error you keep reading on your screen.

1. Check internet connection: Make sure you’re connected to a stable Wi-Fi network. Unstable connections can cause disruptions during the update process.

2. Charge your device: Your battery should be sufficiently charged (preferably above 50%) before initiating the update.

3. Update via recovery mode: If standard methods fail, updating your device through Recovery Mode clears temporary files that might be causing the update issue.

4. “Factory Reset”: As a last resort, perform a factory reset. Remember, this will erase all data, so don’t forget to back up your device’s important files and information beforehand.

Whichever works from these other fixes, it will help you increase the probability of fixing the Galaxy S25 Ultra latest software update issue you’re experiencing.
