Screen Test Pattern Android Application:
by François SIMOND aka supercurio
Note: this application is obsolete and has errors in the values used in color saturation measurements.
I'm working on a much superior, automated approach and don't intent to fix this one.

This app display simple colors on your Android device screen.
Those colors are then measured by a colorimeter or spectrophotometer
in order to build graphs or color profiles.
I recommend using free software Color HCFR:
but I guess alternative solutions like Calman or ChromaPure are fine.
Non-fullscreen pattern is intentional to help with measurement accuracy on displays with content-adaptive backlight/brightness control or brightness consistency issues when displaying large bright zones. Bad ratings for "missing fullscreen options" are lame and non welcome.
(This aspect can be improved)
- A computer
- A colorimeter or spectrophotometer
- Grayscale: 4-128
- Near Black: 4-10
- Near White: 4-10
- Saturations: 4-16
Application also has its own brightness level control
