I purchased karbonn titanium s5 from ezone at avani mall on 16 June 2013 . The mobile service centres are not well equipped and the accessories and spares are exorbitantly charged.
I had my pda and screen broken and the service centre asked for 5400 which was too much and I got it new open market for Rs.2200. The features look etc are far better than micromax canvas. camera is 8 mp and front is 2 mp and the mobile is very slim to hold compared to samsung and micromax.
Currently better features and speed is added to this model. I recommend low budget buyer to buy this model compared to micromax.
