Blue Archive Error 80103: Causes and How to Fix “Not Enough Free Storage”

Few things are more frustrating than settling in to enjoy the latest Blue Archive event, only to be met with an error message. Error 80103, typically accompanied by the phrase “Not Enough Free Storage,” is a common but often misunderstood issue.

While the message seems straightforward, the fix isn’t always as simple as just deleting a few photos. Here is everything you need to know about Error 80103 and how to solve it for good.

What Does Error 80103 Actually Mean?

On the surface, the game is telling you that your device doesn’t have the required space to download new data (updates, event assets, or voice packs). However, many players encounter this error even when they believe they have enough free space.

This happens because:

1. The game requires double the patch size. Blue Archive downloads compressed files, unpacks them, then deletes the originals. You need temporary free space equal to the patch size + the final install size.
2. OS “reserved” space. Modern phones (especially iOS) reserve 5-10% of storage for system operations. The game sees available space, but the OS blocks usage beyond a safe limit.
3. Corrupted cache data. A mismatch between reported free space and actual usable space can trigger false positives.

Fix 6: Move to External Storage (Android Only)

If your phone has an SD card, you can force part of the data to external storage, though this is risky for performance.

1. Go to Settings > Apps > Blue Archive.
2. Tap Storage > Change (if available on your Android version).
3. Select SD Card.
4. Warning: This can cause lag during Live2D animations. Only use for low-end devices.

Step 2 — The In-Game Resource Deletion

He reopened Blue Archive (it still launched, because the patch hadn't installed). On the title screen, he tapped the Menu (three lines) → Download Resources → Delete Unnecessary Resources. This removed voice lines and past event cutscenes for events he'd already cleared. Freed 1.2 GB.

Now he had 2.1 + 0.8 + 1.2 = 4.1 GB free. Enough for the 3.8 GB requirement. He held his breath and hit Update. blue archive not enough free storage 80103

The progress bar moved. 10%... 50%... 90%...
Error 80103 again.
