In an earlier video, I tested my phone as a lux meter and sound level meter. With the spectrometer out for measuring the infrared sensor under the screen, I thought I might as well test the spectrum from the AMOLEDs in the screen. Here are the recordings.
In my next public video coming end of March I will continue testing my phone. This time focusing on the 3-axis magnetometer. Can the phone be used as a 3-axis gaussmeter?
