Well got this as a gift from wife .its a good phone and have used it for a week.have been using moto E for past year and honestly moto E have better display as its 256ppi compared to 220ppi for this set but still this set display is good enough.but the grand prime 3G is better dn this as the 3g version has qualcomm cpu with adreno gpu but this 4g version has marvel cpu which is bit skower n hangs atimes when playing very high end 3G games but normal gaming n usage is good enogh again comparing with moto E the moto E performs way better with zero lags even while gaming due to qualcomm cpu n adreno gpu which this 4g model does not have.plus this 4g version has no light sensor ence no auto brightness control unlike the moto E or tge 3g version of this model which had it.
But this 4g model has OTG support n suprisinly its not menioned anywhere but has it n I have tested it.
Battery life is really good.lasts me more tgen a day with good gaming 3g net always on n few calls n lots of web surfing.
This phone is good buy but for mid level usage nof for hard core gamers as my moto E beats it in all departments .so if u want a branded phone with good ter sales service go for it.else go for moto or lenovo sets.
