How did you find that the X only has 4 slots for adjustments?
At the bottom of the setup, there is an option to select the number of slots, I am using 8. Are you saying that they are not all being used?
I never looked but I will tomorrow when its light out. Speaking of direct sunlight, I was setting the brightness up outside one day and in direct sunlight, while aiming the phone at the sun, the reading was only 3680, if that is correct then with your settings the phone would never reach full brightness with the the high setting being 8600.

OK, checked with a lamp and it does read 8600 raw. When I was seeing those other numbers from my last post it was indeed filtered from having the average on. Did not realize that, thank you. Will try this out tomorrow as I'm going in and out.
