“Universal” values for light sensor?

Question

I tried to registret the light with two smarthphones. My samsung galaxy return values from 1 to 10k (<1k if i have a roof or something else over me, or 9000 if there is nothing over me)., while an old xperia return values from 1 to 100k (<10k if i have a roof or something else over me, or 90000 if there is nothing over me). Is there a way to find a "universal value" or something like this? In the android documentation i didn't find anything useful.

There is no "universal" value, but getMaximumRange() on the Sensor should tell you the highest possible value for that specific device that your app is running on.
