Fallback mode active.
This mode visualizes phone orientation/motion changes only. It is not magnetic field data and should not be interpreted as RF or EMF strength.

How to test:
Move the phone slowly near speakers, magnets, chargers, metal objects, or powered electronics.
Sudden changes may appear as spikes. Wi‑Fi, LTE, 5G, and Bluetooth RF power cannot be measured directly by this web panel.
This is not a professional RF/EMF meter. It uses browser-accessible phone sensors only.
Calibration Guide
- Move away from large speakers, magnets, metal desks, and chargers.
- Hold the phone steady for two seconds.
- Tap Calibrate to set the current baseline.
- For compass/orientation problems, slowly move the phone in a figure-eight motion.
- If the mode badge says Fallback, the page is not reading magnetic field strength.
Use Demo only to preview the interface on unsupported devices. Demo data is simulated.
