The only issue with Micromax is that YMMV for the phone. I have seen people whose phones work fine without any issues. And there are those who face minor QC issues like the battery not charging fully/dying quicky, or the touch not working properly. And lets just forget the bloatware! These issues could be avoided if they do proper QC.
And if this is a Coolpad F2, then I feel its going to be a hit and miss again. I have a Spice Coolpad Mi 496, based on the Coolpas 7268. Build quality is not that great, but thanks to a custom ROM, the device at least works!
