Troubleshoot repeatable USB and Bluetooth drops with controlled power, firmware, cable, pairing, and host checks.
PS5, Xbox and Switch Troubleshooting
Separate common browser inputs from platform-only features that require official console or app checks.
Controller Deadzone Test and Calibration
Use repeated center evidence, official calibration, and reversible settings before considering repair.
Pressure Sensitivity and Trigger Range Checks
Check whether a control is analog, then compare its mapping, range, release, profiles, and supported software.
Controller Motion and Gyro Troubleshooting
Use official calibration and native motion tools while respecting the browser tester's IMU limits.
Controller Not Charging? Safe Checks
Separate cable, power-source, port, firmware, and battery symptoms before considering service.
Bluetooth vs Wired Controller Connections
Compare connection stability and browser-visible behavior without treating browser cadence as input latency.
Connect a Controller to iPhone or Android
Separate mobile pairing, browser exposure, game support, mapping, and perceived delay without unsupported latency claims.
Gyro Aiming Setup and Calibration
Use supported game or mapping tools for motion data that the standard browser Gamepad API does not expose.
Squeaky Controller Stick: Clean or Service?
Separate sound, friction, and input symptoms without spraying lubricant through the controller shell.
Hall Effect vs Potentiometer
Compare contactless and contact-based sensing, remaining wear paths, calibration, and browser measurement limits.
Controller Polling Rate Test and Browser Cadence
Interpret browser-observed cadence correctly and understand the risks of driver changes.
Detecting Button Bouncing
Use the input timeline to spot browser-visible double inputs or stuck-button patterns.
Advanced Diagnostics & WebHID
Understand browser-observed input timelines, button bounce symptoms, and Sony WebHID output controls.
Clean a Game Controller Without Teardown
Use conservative power-off, no-submersion, manufacturer-specific cleaning and full-drying precautions.
Set Game Controller Deadzones Safely
Tune game-specific deadzones from repeatable symptoms instead of copying a browser value as a universal setting.
