Get back into the fight.

Start with the smallest changes

Check that the installed game came from the official store and review its eligibility for your device. If the problem began after an update, record the game version and operating-system version before changing settings.

Apple’s general app guidance starts with closing and reopening the app, restarting the device and checking for app or operating-system updates. Google’s Android guidance likewise starts with restart and updates, then suggests force-stopping an affected app. Try one step at a time so you can tell what helped.

Controller connected, but no useful input?

• Check that the controller is charged and visible as connected in the phone’s Bluetooth settings.
• Check that it is not still connected to a different device.
• Reopen the game and test movement before testing a long combat sequence.
• Read the game prompts for the active input method.
• If movement works but defense fails, practice timing separately from connection troubleshooting.

Protect your save before destructive steps

Deleting an app or clearing its data can remove local progress. Apple warns that deleting an app may lose stored data; Google explicitly warns that uninstalling erases data saved in the app.

Before following those steps, establish what backup or recovery options your installed game actually offers. Do not assume that an account sign-in, an achievement system or a previous purchase also backs up the campaign save. Prefer reversible checks first.

Make a useful problem report

If the issue persists, use the developer support route linked by the official store. A concise report should let support distinguish a launch problem from a scene-specific crash or an accessory issue.

• Phone or tablet model.
• Operating-system and game versions.
• Where it happens and the actions that reproduce it.
• Whether touch and controller behave differently.
• A screenshot or recording of the error, with personal information removed.
