Usually when I am trying to check the recent history of a sensor on my phone – i tap on the sensor, get more info. I usually need to change the time period – go to the history plot.
Then I tap the screen to read a data point and – bang – I am back to the more info.
This also happens on desktop, but it is not so annoying, since you get the data point on mouseover and the more info panel is small and can be closed.
