I had purchased my micromax mobile on 13/02 and it had been creating problem since then.initially it had charging problem and the service center person replaced the jack.still the problem was not solved.i visited the same service centre in shalimar garden extn-2 thrice for the same problem but gradually the jack broke n now they say the phone cannot be repaired.now it also hangs automatically while operating and the battery backup is also not good.
