I have bad experience with Karbonn S5 Titanium phone, Initially it was working good but after few months its working very badly.
for example: Contact list is not showing, phone is getting hanged and getting switch off, calling issue.
all karbonn phones battery back is very low.even karbon service centres employee also not recommending to purchase this companys phone.
So I suggested that dnt purchase that brand there are so many best brand which is better than karbonn because stating they they work properly but after that its dnt work properly
