The screen is the major worry here - qHD is stretched pretty thin on a 5 diagonal. 220ppi is nothing to write home about, but Samsung has plans on how the Galaxy Grand Prime can compete with the likes of a Moto G( 2014) .
First up is a solid camera department, starting with the 5MP/1080p selfie camera. If you open your gallery and most photos have your face in them, this one is for you. The 8MP/1080p back camera is also on the better side of the midrange market.
Next is the new chipset, Snapdragon 410. ARM claims that Cortex-A53 offers a significantly higher performance over the A7 used in Snapdragon 400. Meanwhile the Adreno 306 GPU offers power savings compared to the 305 in the older chipset. Well cover both performance and power usage in detail in a few chapters, but the Grand Prime wont see a return on the 64-bit chipset unless its updated to Lollipop( which has dedicated 64-bit optimizations) .
