Smart Glasses diagnostic guide

Smart Glasses: test the fault before changing parts or settings.

Check companion-device audio, microphone, Bluetooth and browser-facing components while camera, display and sensor diagnostics remain manufacturer-specific.

4 relevant tests3 first checksBrowser limits stated

Start with a clean baseline

Use browser-visible screen, touch, camera, microphone, speaker, sensor and connection tests as a fast functional inspection, then use the OS/manufacturer for battery-health, cellular, biometric and internal hardware diagnostics.

Live evidence

Relevant checks

Microphone TestCheck whether your browser can detect your microphone and receive live audio.
→
Left Right Speaker TestPlay left and right channel tones separately.
→
Bluetooth LE Browser TestOpen the browser Bluetooth chooser for compatible Bluetooth Low Energy devices in supported environments.
→
Browser Hardware Feature CheckSee which hardware-facing browser capabilities are available before trying camera, gamepad, MIDI, USB, HID, serial, or Bluetooth diagnostics.

First sequence

Do the high-signal checks before risky changes

  1. 1

    Confirm the companion app sees the glasses

  2. 2

    Compare Bluetooth reconnection after a clean restart

  3. 3

    Use the maker's diagnostics for camera, display or sensor failures

Decision points

What the result should change

If touch/camera/audio works in browser but not one appCheck the app's permission and selected input/output before resetting the phone.
If charging is the symptomSeparate adapter wattage, cable capability, connector condition and battery/thermal limits.
If the device is used/refurbishedTest all user-facing functions before account transfer/payment, not after.
Browser can help check
  • Test browser-visible audio paths on the connected host
  • Request compatible BLE devices in supported browsers
Browser cannot prove
  • Inspect waveguide or display optics
  • Test embedded cameras or sensors generically
  • Read protected firmware diagnostics

Repair boundary

Know when to stop browser troubleshooting

  • Swollen batteries, exposed cells or severe heat require immediate service handling.
  • Do not insert metal objects or liquids into charging ports.
  • DeviceOK cannot verify IMEI ownership, activation lock or water-resistance integrity.

Used-device inspection

What to verify before paying or signing off a repair

  • Touch across the whole panel and pixel/color inspection
  • Front/rear cameras, microphones, speakers and buttons
  • Charging/data port, Wi-Fi/Bluetooth and manufacturer battery-health screen
