An update may download a compressed package, keep the old version and unpack new files before cleanup, so temporary space can exceed the listed patch size.
Short answer: Free internal storage well above the patch size, restart the phone and update through the official store.
Check the likely cause first
- Compare free internal storage with the full installed game size.
- Check for pending system or app updates using the same temporary space.
- Identify removable videos, offline media and old downloads.
Fix it in the safest order
- Back up photos and confirm game account recovery.
- Remove safe personal downloads and unused apps, not game data.
- Restart to clear completed temporary tasks.
- Run the official update and keep the phone powered and connected.
Before changing storage, account or network settings, confirm that the game came from its official store listing. WP Phone does not recommend modified APKs, unofficial top-up pages or account sellers.
How to confirm the fix
After installation, confirm the game version and check whether temporary storage was reclaimed.
What not to do
- Do not move random game folders between storage devices.
- Do not use a modified smaller package.
When to contact support
Contact the publisher if the official patch repeatedly consumes space without completing or cleanup never occurs.
Use the official game directory to verify download routes, and review the safe download checklist before reinstalling.
