Very smooth processing. touch is very good. after updating the phone the heating problem is very less in comparison to redmi 2. 2gb ram is huge for this phone.
Only 700mb of is used by miui. the rest is more than enough for multi tasking and heavy gaming. lags found in redmi 2 are overcome in redmi 2 prime. no much difference in redmi 2 and prime except ram and internal memory. dont think. juz go for it if ur budget is less than 10k. Its perfect for d money paid. worth every penny
