I want to know about the screen size and density of the Samsung Galaxy Y. Which category of screen size (small, normal, large,x-large) or density (ldpi, mdpi, hdpi, x-hdpi) is its screen? Any references would be helpful.
Using the following diagram from developer.android.com you can see where it falls in the specs:
It's 3 inches diagonally - it falls in the "small" category.
It's 133ppi - which is definitely ldpi.
