One item I found is that if you are having trouble seeing your screen in the strong sun and bright light, make sure you have the "Automatically Dim Backlight" option set to ON.
Options > Screen/Keyboard > Automatically Dim Backlight > select ON
Even if you have your backlight set to 100%, it still may not be enough. Apparently the sensor (behind the flashing LED) will actually increase the backlighting to MORE than the 100% in very bright light, but only in the Automagically mode.
It has made a difference for me.
