Using this mod may decrease battery life, decrease screen life and/or quality, cause overheating, cause your phone to blow up or cause other damage to your phone. Use at your own risk. I am not responsible for any damage this mod causes to your phone.
This Mod will increase the max brightness of your phone by about 10%.
Auto Brightness must be turned off for this to work.
Root is required for this Mod.
Download and run app attached to this post.
echo 1 > /sys/class/backlight/panel/auto_brightness
If you reboot or enable auto brightness you have to run it again.
The best way to tell if it worked would be to run it when your screen is already at full brightness. You'll see it go a bit brighter.
Tested on T-Mobile Note II, but this may work in many Samsung Galaxy phones.
