First of all I want to tell that u cannot get a better phone than this in this price segment. It has abig 5.5 inch 1080p display which is pretty decent, the color reproduction and viewing angles are great.The 13mp camera on the back is decent for photography and also can record full hd videos @1080p resolution and is provided with lots of features.now the front 5mp camera is just good but not great for selfies.performance wise it is very good.i did not found any lag during any moderate to heavy usage.
And the battery of 3000 mah is very good.
It can last over 1 and half day with moderate usage and a full day with heavy usage.overall for the specifications and the price of this phone it is the best phone you can buy in its price segment
