I was buy this micromax Q7 on 2010 in month octomber 14 from authorised shop. After one month I faced many problem. It big issue of hang. After it I go to the service center. They said that within five day we repair but they reapi after 15 days and say that it have update problem.
Phone was getting heated up while playing big ram game and it automatically switched off. I again go to service center they told me PCB is faulty and need to be a new fresh PCB.
The changed the entries setting of the phone and it was working only in loud speaker.
Do not get belived on fraud advertisments.
