Why Samsung should be nervous about its premium Galaxy smartphones - CNET
This link is spot on and mentions 2 things I believe in specifically which I will get to.
Firstly, apart from Apple, the whole premium smartphone market has slowed. The article I provided shows that there is a saturation in the premium market. The problem is that Apple dominates the high end and there is a plethora of cheaper Android devices with good specs in the lower end. A phenomenon this article states as the emergence of "good enough" phones. Much cheaper android phones but with still plenty good specs for a lot of people.
The S6 and Note 5 are steps in the wrong directions. Samsung should have retained their distinguishing features and make them better with innovations. The S6 should have had say a carbon fibre removable back with the SD card plus waterproofing. The battery should have been significantly bigger, the whole phone slightly thicker than the S5 and there should have been only 2 variants-a 64 and 128 GB version with SD card. The Edge version was an extremely expensive gimmick that cost a fortune to develop and didn't sway people to Samsung. Imagine the enormous savings if you only had to produce 2 versions minus the very expensive to produce curved screen.
There should have also been class leading front facing speakers. Samsung could have also differentiated itself in the top end by having a xenon rear flash and front led flash together. If you did all that and made it a bit cheaper, that type of S6 would have sold big time. Samsung also could have made huge savings in time and money ordering a processor from Qualcomm rather than developing and making it themselves.
As the article suggests, Samsung needs to open a second formal midrange line, say Galaxy M, to compete with OnePlus etc. A midrange phone that costs no more than the cheaper Chinese androids would be effective against them. Something like re releasing the S5 in a new body and throwing in a 5mp front camera. With say 32 GB standard plus SD.
Those are my thoughts. I was correct about my sales predictions for the S6 and I think the "new" Note 5 will do worse. And the S6 plus will be a sales disaster.
So to sum, this is how I would have made the S6:
64/128 GB plus SD.
Carbon fibre removable back, phone marginally thicker than the S5.
Battery at least 3200mah.
Front facing speakers equal to HTC.
LED front flash, xenon rear flash.
Waterproofing without flaps.
Now tell me that wouldn't have sold far better than the current S6. And look the time and cost savings. 2 versions only, not developing your own processor, no costly edge version.
