Is there a better smartphone than Xiaomi Redmi 2 Prime?

You can get Swipe Elite Smartphone 2 at that price range with same configuration as stated by you above. It was released few weeks back and it has enough features too. Swipe is Indian company and moreover, I saw that there is similar specs from Intex brand Smartphone as well. You may search and try both of them.

No doubt, Xiaomi Redmi 2 Prime smartphone is a different gadget with unique style. If you spend a bit then you may get Note 3 Smartphone from other well known brands.

Well, I must say the Xiaomi RedMi 2 Prime is a great device in its own right. The impressive camera, 4G connectivity and a good performance make it a force to reckon with at this price band. Only issues could be the lack of latest Android Lollipop update on the device and the heating problems that arise at times - though not consistently.
However, if you are ready to sacrifice good specs for a brand, I would advice you to go for Motorola Moto E 2nd Gen. It should be noted that the phone does not have the spec sheet that the RedMi 2 Prime offers you.

I didn't find a single phone priced under 7K that has 2GB RAM and quad core processor. That goes to show you that Xiaomi Redmi 2 is the best bet at that price.

Here are some of the phones that I have found around flipkart and amazon.

1. Intex Aqua Power HD
2. Micromax Canva Nitro A311
3. Intex Cloud 4G Star
4. Matrixx Sonic
5. Lenovo VIBE P1m

Though the above phones are priced above 7000Rs. They have different configuration set and are closer towards your requirement.

I'd say stretch the budget and go ahead and get Redmi Note. And if you don't like Xiaomi then maybe Lenovo K3 Note is a good option for you.
