    0 of 4 completed
    1. Capture the exact failure state

      Reversible

      Check whether the feature is grayed out, missing from settings entirely, or present but unresponsive when used. Expected behavior: hold a stable supported charge and data connection without movement.

    2. Isolate the component boundary

      Reversible

      Test two known-good certified cables and inspect the port externally with power removed. Test the same feature in a different app that uses it, and with recently installed apps disabled or in Safe Mode. Boundary to separate: port versus cable, adapter, debris, liquid warning and host device.

    3. Correct only the proven cause

      Reversible

      Remove only loose dry debris by approved methods or replace the proven cable/adapter. Re-enable the permission or setting, or update/reinstall the one app where it fails.

    4. Verify and stop safely

      Reversible

      Confirm the feature works from a cold restart in at least two different apps. Stop for heat, corrosion, liquid, bent contacts or a loose/burned port.
