I had purchased this phone at 12.5k from a leading online shopping site thinking it will be a good product, but I was dissapointed.
I had to sell this phone in 2months for rs 9k.it just had too many problems,
I am a fifa16 maniac, i intalled it on core 2 and it just cudnt offer me a smooth play.
it lag alot and sometimes use to end abruptly, games like asphalt8, fifa15, pes etc do not function properly on galaxy core 2.this were my experirnces, i hope it will help u big time.
but an honest advice would be from me is to not to opt for this phone, even angry birds 2 lags on this device.
