This isn’t so much a marketing problem but a manufacturing one. According to reports, word has it that Samsung’s manufacturing partners have run into issues trying to produce the curved glass display used in the handset. Apparently the yield for the glass displays have dropped below 50% and while Samsung did anticipate running into issues given the curved nature of the display, it seems that they did not expect it to be that bad.
It has also been reported that the curved displays will be rather pricey and has been estimated to cost $25 per piece, due to the complicated molding process and low yields. It is unclear if the expensive displays will cause the handset to be priced much higher or if Samsung will absorb some of the costs, although there is a good chance it will be the former.
The low yields could also hint that the Samsung Galaxy S6 Edge might be delayed from being released, or it could be possible that we might see low supplies at the start, although given the unique nature of the phone we can only imagine that there will probably be more curious customers than willing ones, at least at the start so supply might not necessarily be an issue.
