Update Call of Duty: Mobile and the device operating system, restart the device, and test after each step. On Android, clear the app cache; reinstall only after confirming the account is linked because guest progress can be at risk.
1
Protect account access
Before clearing storage or reinstalling, confirm the COD Mobile profile is linked to a supported account. Do not risk an unlinked guest profile.
2
Restart and update
Restart the device, install the latest iOS or Android update supported by it, then update Call of Duty: Mobile from the App Store or Google Play.
3
Close background apps
Close other running apps and confirm enough free device storage, then launch COD Mobile again.
4
Use the Android cache step
On Android, open Settings > Apps > Call of Duty: Mobile > Storage and select Clear cache. Do not select Clear storage unless the account is linked and you understand the local-data consequence.
5
Check the connection
Test a stable Wi-Fi connection and restart the router if other apps are also unstable. Avoid VPN or proxy changes unless required by the network.
6
Reinstall only after linking
If Activision guidance calls for reinstalling, first verify the profile is linked and the login works. Remove and reinstall only from the official store.
7
Report a repeatable crash
If it still crashes, report the device model, OS version, COD Mobile version, free storage, crash point, network type, and whether a new session reaches the menu.

If it does not work
If the crash starts only when loading one mode or resource pack, record that boundary and avoid repeatedly downloading the same optional content before reporting it.
If the account is still an unlinked guest profile, do not clear app storage or reinstall; first use an in-app supported linking option or contact Activision Support.
