How to Fix Clash of Clans
Crashing

If Clash of Clans keeps crashing or freezing, follow these steps in order. Crashes are almost always local — GPU drivers, corrupted files, or conflicting software — rather than server-side issues.

Step-by-Step Fix

1
Update Clash of Clans
Open the App Store (iOS) or Google Play (Android) and install any pending Clash of Clans update. Running an outdated version after Supercell pushes an update is the most common cause of crashes.
2
Restart your device
Power your phone or tablet fully off and back on before playing. This clears cached memory that accumulates over time and causes Clash of Clans to crash on launch or mid-session.
3
Clear app cache on Android
Go to Settings → Apps → Clash of Clans → Storage → Clear Cache. Do not clear app data, which would log you out. Cache-only clearing fixes most crash issues without affecting your account.
4
Free up device storage
Clash of Clans needs at least 2GB of free storage to run and cache game assets. If your device storage is nearly full, the game crashes when trying to load or save data. Delete unused apps and photos to free up space.
5
Ensure your OS is updated
Supercell regularly raises minimum OS requirements. Update your iPhone to the latest iOS or your Android to the latest available version for your device. Running an OS older than Supercell's minimum causes crashes.
6
Reinstall Clash of Clans
Uninstall CoC and reinstall from the App Store or Google Play. If you have a Supercell ID, your village is safely stored server-side. If you use Google/Apple account linking, stay signed in on your device before reinstalling.
Is it server-side?
Check real-time player reports — if reports are spiking, it's on Supercell's end, not yours.

Frequently Asked Questions

Why does Clash of Clans keep crashing on my phone?

CoC crashes are usually caused by an outdated app version, insufficient free storage, low device RAM, or an outdated OS. Update the app, free up 2GB+ of storage, restart your device, and ensure your OS is current.

Clash of Clans crashes when I start an attack — why?

Crashes at attack start are typically caused by the game running out of RAM while loading the enemy base, or a network timeout during the attack initialization. Restart your device before major attacks and close all background apps to maximize available memory.

Clash of Clans crashes immediately after loading — how do I fix it?

Instant crashes after the loading screen usually mean the app data is corrupted. On Android, clear the app cache (Settings → Apps → CoC → Storage → Clear Cache). On iOS, offload and reinstall the app. Your village is safe as long as you have a Supercell ID linked.
