Screen brightness issue after security update

[SamarjitSaha]

I just did a update(SM-N770F) which are related to WiFi, Samsung Keyboard ,Camera and Messages.

After the boot up, every updates are perfectly fine and improved, but I don't know why I can clearly understand the brightness have been reduced.
