Screen Test Pattern Android Application:
by François SIMOND aka supercurio
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.
(This aspect can be improved)

- A computer
- A colorimeter or spectrophotometer
Features supported:
- Grayscale: 4-128
- Near Black: 4-10
