Controller input works on one side but not the other
Test both sticks, triggers, buttons, and the D-pad in your browser, then find out whether one side is blocked by settings, connection, or hardware.
Does your controller respond on the left but not the right, or do controls on one side stop working in a game? The cause could be a worn control, a wireless connection issue, or a game layout that has changed.
Test the controller outside the game first. The Gamepad Test shows input from buttons, sticks, and triggers, which helps you tell whether the controller is sending the input at all.
Test both sides of the controller
- Open the Gamepad Test and connect the controller. If it does not appear right away, press a button to wake it and check again.
- Move the left stick in a circle, then press each direction on the D-pad. Watch for the corresponding input to change on screen.
- Repeat with the right stick, face buttons, shoulder buttons, and triggers. Move each stick slowly to its edges, then return it to the center.
- If you use more than one controller, disconnect the extra one and test again. This helps you avoid checking input from the wrong device.
Test each control more than once. A loose connection or worn contact may work intermittently, so a single successful press does not rule out a fault.
What the result means
One control or group never registers
If the same stick, button cluster, or trigger stays inactive each time, the issue is likely with that control, its connection, or the controller itself. Try another connection method and device before deciding it is broken.
The inputs register in the test but fail in one game
The controller is sending input to the computer. Check the game's controller layout, control bindings, and selected input device. A custom profile can assign a control differently or disable it.
Inputs appear only when you press hard or move the stick far
This may point to wear, dirt, or a calibration problem. If the same control behaves this way in several games and on another device, the fault is more likely in the controller than in a game setting.
Inputs stop or jump around when you move the controller
A cable, USB port, battery, or wireless link may be unstable. If the problem changes when you move the cable or controller, check the connection before changing game settings.
How to fix it
- Check the game's control layout. Open the game's controller or input settings and confirm that the missing controls are assigned as expected. If you use a custom layout, switch back to the default temporarily and test again.
- Reconnect the controller. For a wired controller, unplug it and try another USB port. For Bluetooth, disconnect it and pair it again. On Windows 11, check Settings › Bluetooth & devices › Devices. On macOS, check System Settings › Bluetooth.
- Check the cable and battery. Try a known data-capable USB cable, since some cables only provide power. For a wireless controller, charge it or replace its batteries, then test the controls again.
- Close other apps that use the controller. A controller utility, remapping app, or another game may apply a profile or keep the device busy. Close those apps and reopen the game.
- Reset custom mappings. If you changed button assignments in a game or controller utility, restore the default layout. Test before adding custom changes back one at a time.
- Restart and update the device. Restart the computer or phone, then install available system and controller firmware updates through the device maker's update process.
- Try another device and game. Connect the controller elsewhere and test it in a different game. If one side still fails, the problem is less likely to be a game-specific setting.
On a phone, remove the controller from the Bluetooth device list and pair it again. Android menu names vary, but the setting is usually under Settings › Connected devices › Bluetooth. On an iPhone, check Settings › Bluetooth, then reconnect the controller.
When the controller may be faulty
If the same controls fail in the Gamepad Test and in multiple games, on more than one device, you have strong evidence of a controller-side problem. A damaged cable, worn button contact, or faulty stick module can cause one area to stop responding while the rest still works.
For a controller under warranty, contact the seller or manufacturer before opening it. If it is out of warranty, compare the repair cost with the cost of replacement. Avoid pouring cleaner into buttons or sticks, since liquid can damage the electronics.
Why a game can behave differently from a test
A browser test checks whether the browser receives controller input. It does not confirm that every game supports the same controller features or uses the same button layout. A game may ignore an input, map it to a different action, or support only some controller modes.
If the Gamepad Test shows every control working but one game does not, focus on that game's settings and controller support. For other button-specific checks, see Controller buttons not responding? How to check.
