Karbonn S5 has these disadvantages:
Viber mic not working, same for Fring, Line, KakaoTalk(person you’re talking to cant hear you)
Skype video call not supported
Had given my Karbonn S5 Titanium for service, its touch screen became unresponsive.
Still waiting for the mobile to come back after 2 months. Have sent them a notice, if they dont respond
will move to consumer court.
Buy Karbonn phones at your own risk, since their service centres are pathetic and super unprofessional.
Try calling their toll free and customer care numbers, you definitely can not reach any one.
