Calibrate the compass
By this time, I have used one of the applications from Google Play to calibrate the compass. After updating this application, I see ads that are often annoying. I downloaded another application for calibrating the compass, but it also has bored advertising.
I'm wondering why by this time the locus does not have its own function for calibrating sensors
I understand that, for calibration, you do not need anything special, enough to figure out the figure 8, but you could not add at least some kind of hint at the need for calibration.
I propose to implement it in the following way so that the map rotation button notifies the color change about the need for calibration, just like the gps button or live-tracking in the panel. Green - does not need to be calibrated, yellow or red - requires calibration
