I bought micromax a111 from amazon.in on july 17 2014. From then this mobile is creating problem. I thought of going multiple times to customer service center but because of time constarint I couldnot. My brother went to service center they sent him saying this is not under warranty n all that. Issues: cameras are not working properly 2. Speaker is not working properly. 3. Slow I trust amazon more than samsung and any other companies. I bought yureka also that set is working fine.
