WARNING:
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%.

Note:
Auto Brightness must be turned off for this to work.
Root is required for this Mod.

Instructions:
Download and run app attached to this post.

Or. ..

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.

Seems to have worked, but comparing brightness on one device by eyes is tough. It certainly didn't break anything though!

screen filter or root dim work. they place a transparent black overlay on top of the screen and dims everything. works best with oled/amoled screens as the overlay actually lowers the light output where if you were using a traditional led backlight it'll still have the same brightness but the hue of everything would be reduced.

I also find Galactic Night to be useful. I often use red mode if driving so I don't have a mini spot light in my car.

Look for an app called "screen dim"
It lets you take your brightness and contrast down to ZERO.

Caution: can be really hard to see if you do that. I know, I've spent 10 min in a dark closet trying to open the app again after accidentally backing out of the app with the screen all the way down... pm me if you can't find it and I'll get you a copy.

+1 for Galactic. I used this on my old GS2 and loved using the red filter for reading at night. It was less bothersome for my wife and it made me fall asleep easier because it doesn't have any blue wavelengths, which I think I read that it can cause difficulty in sleeping.

Haven't rooted my GN2 yet but glad to hear it works on it.

i'm sure i'm alone, but i'm haven't seen much demand for INcreasing screen brightness as opposed to DEcreasing brightness. what kind of uses does this mod have?

but I have a Note 2 not an iPhone 5. Personally i think the screen is plenty bright enough. Not trying to troll or nothing, just want to understand better, but i like i said i personally dont see many requests for a brighter screen. how would one benefit from having a screen brighter than the brightest stock setting?

    Screen brightness is a big deal, especially outdoor.

    I mean, ask Apple why the screen in the iPhone5 goes so bright.

    In the end, I'd just about personal preference. If your screen can be brighter then why not?
