Record the exact Nexus version, controller model, USB/Bluetooth connection, active profile, virtual output and repeatable steps. Test input separately from grip vibration, trigger resistance and lighting.
Use About & Help → Connection Checks → Export Diagnostic ZIP. Identifiers are redacted by default; review the archive before sharing. Raw log export is explicitly unredacted.
Use a backup and a separate test profile before attempting a selective reset. App-file rollback and settings/profile restore are different operations.
Still stuck?
Prepare a support report or return to the troubleshooting hub. A browser controller test can help observe input, but does not verify Nexus mappings, virtual output or every feedback feature.
