Biggest. Camera. Ever.Intriguingly the source also revealed that the unconfirmed Nokia 803 will sport one of, if not the largest camera sensors ever on a mobile phone.Nokia has produced impressive camera phones in the past and we are curious as to what the 803 will offer us: 14MP, 16MP or even 20MP perhaps?Rumours suggest that the Nokia 803 will be released in May – which means there is a small chance we may get a sneak peek at MWC 2012 later this month.
