[ROOT] Decrease Brightness In Your Android Below The Minimum Level

Soooo...
Today I have a useful tutorial for all android users (With root access)...
You can now reduce the brightness below the least level that your phone allows by default...

Tutorial

1. Make sure your phone is rooted...[IF YOU ARE NEW TO THESE THINGS A BACKUP IS RECOMMENDED]

2. Download any file explorer that allows root permission... (I'm using ES File Explorer)

3. Go to the options in the file explorer and enable root access...

4. Now mount the system as R/W instead of R/O...
For ES file explorer go to the tools and touch the root explorer option and select the mount option now change everything to R/W...

5. Now go to the device directory...

6. Navigate to sys>>class>>leds>>lcd-backlight...

7. Here you will have a file named "brightness"

8. Open it as Text file...

9. Now go to menu and select edit...

10. Here you will have your current value of brightness (MAKE SURE AUTO BRIGHTNESS IS OFF)...

11. Edit the value to any value you want... 

**Decrease it gradually just for precaution bases...

12. when you have a comfortable brightness level you can just go back and save it ... 

DONE! :D

13. For further changes if you wish you can add a shortcut to your home screen so you can directly go and change the values...
