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?

I'd be interested in what happens if you measure the light coming off of the spectrometer app on the computer

Hmm, interesting. The laptop screen will have a RGB spectrum very close to the phone, so if I hold the probe over say the white background in the UV area it will just display a static RGB spectrum. But if I slowly move the probe over the area where it displays the RGB spectrum I may be able to catch how the the three colors are mixed to form all colors... I will give it a try :)
