grand 2 has 5.25 inch with HD display 280 ppi 720*1280
prime has 5 inch 220 ppi so 540*960
prime has very low voice because has 1 speaker not 2 speakers as g2
g2 has bigger and better screen &voice for gaming and movies
g2 has 1.5 ddr3 ram prime 1 ddr2
so g2 is better for multitasking
prime hasn't light sensor or multiwindows or one hand operation features as g2
5 mp front cam isn't good for video calling so 2 mp front cam is much better than 5 mp for viber or skype video call because more than 2 mp u will need very fast internet to be fast and clean video
prime hasn't alots of Samsung applications like music player, my magazines ,my album ext...but g2 has these apps
prime hasn't keypad light for back and list it's look like cheap phones as core2
grand 2 is win in every way
because grand 2 is the boss of grand series and getting updates like grand 1&2 while prime and neo is secondary won't get any update so spend little more money and go for grand2 the king of grand series until grand 3 coming
not very prime at all.. dissapointing. Only thing i got high hoped id battery life, great capacity for the screen
No LTE will limit its appeal in established markets. This is unfortunate.
And what is the "prime" factor of this phone? Everything from screen's brightness and sunlight reflection, camera and benchmarks, loudspeakers to design, everything is just medicore...
