Hey pal....read the DisplayMate review.....Starting with the gs5 samsung is using a diamond matrix and not pentile.there ppi is exactly what they claim and it don't matter what color each pixel is because they are in a diamond matrix and use bigger pixels on the weaker colors.
They still have exactly the number of pixels they claim and you somehow you think because some pixels are more red then others the phone has less ppi?
Say it out loud so you can remember it because you always mention this in threads about samsung screens.
The new amoled screens use diamond matrix pixel array....now say it 100 times so you can remember it.
Now apologize for your condescending tone.
I forgive you.
