Words are not clear on my Samsung Galaxy Y phone?
The Samsung Galaxy Y is a low spec phone and most importantly this can be observed with its display.

Some common models in comparison (by resolution, pixel per inch, screen size, price):


Galaxy Y: 240x320, 132 PPI, 3.0in, 110EUR
Galaxy Ace: 320x480, 165 PPI, 3.5in, 190EUR
Galaxy Nexus: 720x1280, 316 PPI, 4.65in, 410EUR


The text is blurry because there are much less pixels per inch to allow it to display text beautifully. You most probably can see individual pixels without a magnifying glass in comparison to "HD" displays like the Galaxy Nexus' and such.
