This phone I used for more than 6 months and this is the bestest smartphone I ever seen in the market.
This phone I bought for 5000 from Flipkart and when I saw the features I shoked because the best market smartphone samsung does not give 4g enabled smartphone in this price level.
This smartphones is lag free and can do multi tasking this phone comes with 2 gb of ram.
Its camera is ossum it captures great picture in day as well as in low light.
Its battery bakup is also good and does not heat.
You can use it for whole day it doea not lag or hang but if you use heavy games I can lag but if you use it safely, you can use it for 3-5yrs without any problem.
I can recommend you to use once this smartphone.
