Resolving the "Stuck at 20% Loading Screen" Bug in Brawl Stars
Why Does Brawl Stars Get Stuck at 20% Loading?
Brawl Stars freezes at 20% during a loading screen when the client cannot complete a CDN asset download — typically caused by a corrupted local cache, a regional Supercell server delay, or insufficient device storage blocking patch extraction. This is a client-side error and does not require a reinstall in most cases.
Quick Diagnostic Table
| Symptom | Likely Cause | Fix Priority |
|---|---|---|
| Stuck at exactly 20% every launch | Corrupted cache file | High — clear cache first |
| Stuck after a game update | Incomplete patch download | High — force re-download |
| Stuck on Wi-Fi but not mobile data | ISP/CDN routing issue | Medium — switch network |
| Stuck only on one device | Low storage or RAM | Medium — free space |
| Stuck across all devices/networks | Live server outage | Wait for Supercell fix |
How to Fix Brawl Stars Stuck at 20% (Step-by-Step)
Fix 1 — Check the Brawl Stars Server Status
Before touching your device, verify the issue is not a live outage. Visit status.brawlstars.com or check the @BrawlStars Twitter/X account. If Supercell has posted a maintenance window, no local fix will work until servers are back up.
Fix 2 — Force-Stop and Clear App Cache
- Android: Open Settings → Apps → Brawl Stars → Storage → Clear Cache. Do not tap "Clear Data" — that wipes your local progress.
- iOS: Go to Settings → General → iPhone Storage → Brawl Stars → Offload App. This clears cached assets without deleting your save.
- Re-launch the game and allow the loading bar to restart from 0%.
Fix 3 — Switch Network Connection
Toggle off Wi-Fi and switch to mobile data (or vice versa). Supercell's CDN sometimes routes poorly through specific ISPs. Alternatively, enable a VPN (Cloudflare WARP is free) to reroute asset downloads.
Fix 4 — Free Device Storage
Brawl Stars requires at least 1.5–2 GB of free space to unpack patch files. Delete photos, apps, or downloads until you have 3+ GB free, then relaunch.
Fix 5 — Full Reinstall
- Ensure your Supercell ID is linked before proceeding — go to Settings inside the game.
- Uninstall Brawl Stars completely.
- Reboot the device.
- Reinstall from the App Store or Google Play and log in with your Supercell ID.
Verification
✓ How to Confirm the Fix Worked
After applying a fix, launch Brawl Stars and watch the loading bar progress past 20% and reach 100%. If it fails at a new percentage, repeat Fix 2 (cache clear). A successful launch will show the main village screen within 30–60 seconds on a stable connection.
