Hello friends, Micromax Q 427 is my first mobile. I’m still using it, its memory is also good. I have no problem running it.It does not hang quickly. Its battery is also good. I use it for 6 consecutive hours.I do not have any problem in running the Internet in it. This is a very awesome phone. I continually watch 2-3 movies online on YouTube.I can run the internet for 6 hours in a row. Its version is also quite good.Friends at the end, I would say that Micromax Q427 is a very good phone. I like this very much. Thanks guys, hope you like the review.
