Do not diagnose the whole platform from one experience
Roblox is a platform for separately developed experiences. An input that fails in one place but works in another points toward experience-specific controls or scripting; a signal absent across experiences deserves platform and hardware checks.
Record the exact experience, device, connection and account state. That note is more useful than a generic claim that “Roblox controller does not work.”
Repeatable checklist
- Test the device in Keymap
- Compare a second Roblox experience
- Record exact experience and platform
Choose the correct test for mobile
Touch layouts can place controls near browser or operating-system gesture areas. The touch lab maps where the page actually receives contacts and how many concurrent contacts survive.
Motion sensors require permission and are not exposed in every browser. A missing API should be recorded as unavailable, not reported as a broken phone sensor.
Repeatable checklist
- Run multi-touch with normal grip
- Inspect missed edge zones
- Request motion permission only when needed
Game-specific boundary: Experience creators control many mappings. Keymap can test the input path but cannot promise that an individual experience implements a device.
