The Samsung Galaxy Grand Prime has an ambitious name, but behind it is an ordinary midrange phone. It puts functionality ahead of screen fidelity, throwing all the pixels they could afford at the front facing camera instead. As with other Galaxy Grands, dual-SIM is an option, this one though is the first 64-bit phone in the line.
The Galaxy Grand Prime is headed for developing markets where affordable phones with large screens with underwhelming pixel density are in high demand. In this case we're talking a 5" TFT of qHD resolution (540 x 960px) boiling down to 220ppi. 720p has become common in the midrange these days, but don't let tech geeks and sales people overstate how important it is - most laptops and desktop monitors have half that.
