I bought this phone from flipkart after my lenovo phone started to hang a lot. For 10, 000 rupees it is a very good phone. I have been using it for about 6 months now and it is very good. I use it as my camera, listen to song and also use the internet. The phone as of now is not hanging and is very fast. You can browse very quickly and I have put lots of apps and that has not slowed the phone. It needs a micro-sim card but that can be easily bought now. I have not used it too much for gaming but I think it will run great.
If you are looking for a budget phone just go for this one.
