Adobe RGB on Galaxy S

Galaxy S with AMOLED display can display the entire Adobe RGB gamut
I have taken many test pictures, pairs of the same green objects, one in Adobe RGB and one in sRGB camera color encoding modes
To my surprise most of the times on Galaxy S tablet I see that sRGB pictures are slightly more saturated in green color

I am scratching my head

I'm scratching my head as to why you posted this in the D3200 forum.

There are two things that can go wrong:
1 Samsung screwed up with displaying Adobe RGB on their tablet
2 Nikon screwed up in encoding Adobe RGB images in D
3200
I hope that someone from the D3200 forum will tell me: hey, I tried both formats on the same object and Adobe RGB printed out more saturated and more natural greens than sRGB. Then the problem is with the tablet

Is the software you're using to view your photos color-managed?

....

This is a good question. I use the default Samsung Software plus I tried
other viewer apps including Adobe photo app for Android, so far the results are similar. I looked into the pictures files from D3200 and at least the EXIF header looks correct: for sRGB
- the field color space is sRGB and the field primaries is not present, for Adobe RGB the field color space is not present, but the field primaries has the correct R, G, and B values: R and B are the same as sRGB, and G has the correct Adobe RGB 98 value, different from sRGB.
