The Galaxy S5 tanked, so Sammy has to release the Note 4 early to make up the losses. It's now a pressure sandwich:
Grab premium materials as soon after the iPhone 6 quits clogging the supply chain, but still beat the iPhone 6 to market! All this without cobbling the parts together and putting out a lousy phone.
I'd love to be a fly on the wall in the executive offices of Samsung...
The S5 sold well, it just wasn't the massive record-setting sales people have come to expect from Samsung. HTC, LG, or any of those competitors would kill for those sales numbers.
The big issue, at least here, is that these phones are not worth what they're selling for anymore, because their predecessors are *more* than good enough for the software that's being pushed out these days.
This is why there's this new disruption of super cheap high end phones. Some companies see an opportunity there. Those Chinese Manufacturers are selling phones with Galaxy Note-level Specs for half the price - they aren't just competing... They're making it a no-brainer on which phone the consumer should buy by severely undercutting the prices of competitors. That's why they're getting destroyed in China...
Since they aren't running a platform/ecosystem exclusive to them, they cannot control the competition the way Apple, who competes with no one else in the iOS ecosystem, does.
Right now, I pretty much don't care about software. A new Note with the exact same hardware, but massively revamped software would be more attractive to me than one with hardware upgrades running the lackluster "Revamp" that is the S5's TW software (or any loose variant thereof).
Also, Google doesn't help. They have grown quite slow on the services end and the way they have decoupled so much from Android FW updates means it makes less sense to upgrade as often as we did in the 2010 to 2012 period, where you basically had to upgrade your Android FW just to run the new revamped version of GMail for Android.
These days, people need a benchmark app to tell them their phone is better than the last flagship, because the effects of the hardware upgrades are becoming almost invisible in everyday usage to the majority of users.
Software Design, Software Capabilities (not merely feature bloat, genuinely useful capabilities), and Services stand out a lot more these days than hardware upgrades.
