I bought a new Micromax canvas mega 4g four months ago. Its model is beautiful, its sound quality is also good but when I run some application in this phone the phone is hanging means keeping white disply or stop on the way and no any activity to run or play and big size game is also stop and not runing. then I go to the micromax care but he can’t helps me only say it is resolve but when I reached my home again the problem runing.I am very teasing to face this problem.I think I sell my mobile phone but anybudy do not buy my phone as a second hand phone.so, i can’t suggest anyone to buy this phone. Rest all features like sound, Model, Video quality style and design, and its price are good. Only the problem in its operating system so you can buy but I can’t suggest to buy.
