Color calibration?

[Rob. S. 1,664]

The contrast issue with the Pro¹ led me back to this subject that actually has bugged my with all of my phones so far.

Color calibration (which includes contrast calibration if done properly) of mobile devices has been a problem with Android since it came up; the makers of Android either didn't give it a thought or maybe they decided end users shouldn't be tinkering with it. Only lately new approaches that change the overall color rendition have appeared through overlay functionality (like the multitude of night mode apps), something that tends to get in the way of other things, though.

A seemingly real calibration app with proper color sensor (colorimeter, spectrophotometer) hardware has at some point been published by color calibration specialist X-Rite, but ratings and reviews seem to show that it mostly just doesn't work.

Specifically for the Pixel 2, which can switch between two built-in color profiles, there is a hack for creating a custom profile that requires an unlocked bootloader, root, TWRP and the "EX Kernel Manager" app – I don't suppose this is something that could work with the Pro¹.

And it seems Android 10 does not improve anything there, either; on the contrary, comments on the X-Rite app give the impression that it stopped working on Android 10 even if it used to work on Android 9. 

All if that said, Argyll seems to have a widely functioning solution for Android devices which I stumbled upon just now, and ArgyllCMS is what I've been using for years together with cheap Spyder colorimeters to calibrate my Windows and Linux desktops, laptops and even netbooks. Has anyone experience with this?

Thanks for the heads up, I'll try ColorTRUE later. Have i1Display Pro lying around.

 

Edit: Tried to calibrate with ColorTRUE, i1Display got detected but process gets stuck in Measuring gamut phase.
