It is overall good phone by Samsung but it is overpriced as compared to its price other phones with same features. Its operating system is Android kitkat 4.4.2.

It has dual sim capacity with 3G network connectivity which provide fast web browsing service and downloading as well.
I’m using this phone from one year and I’ve never gone through any software problems within these days. This phone Has 8 megapixel rear and 1.9 megapixel front camera. The camera quality is superb as always the Samsung does. Also it’s sounds quality is awesome. If you are Samsung lover then go for it without thinking for costs as Samsung phone is more reliable.
