It is more of an offset rather than a cut-off, isn't it? I have briefly discussed with Sebastian about it: it might also be some non linearity that “shifts” the fit or some relic of the algorithm for the sensor output data.
Anyway, I am pretty impressed from the result. I would like to share this on Twitter tomorrow morning, same on Facebook a bit latter so that it does not lose attenuation due to some other … announcement.

Hello Jens.
What I see on the measurement done by smartphone it is a negative shift with a clear cutoff of the signal at zero level... I do not see a notable non-linearity... There is no distortion on the measurements done by Sensor Tag.
Greetings

It cannot go below zero, can it? Perhaps the word “cutoff” gets lost in translation: I would not put it that way in German…
Thanks for checking.

Hi,
after passing to phyphox version 1.1.12-beta2 my polarization experiment does not work anymore with the SensorTag
. No indication while running and crash phyphox on a new device. What can be upgraded in order to repair this problem? 
We use this program showing to students the real Malus law. With Brest wishes
Mikhail

First, thanks for reporting that there is also a problem with the SensorTag. We are aware of BLE problems with the beta version on Android and Dominik is already onto it, AFAIK.

The new beta (3) is out. Could you please check if it fixes your issues with the SensorTag?
