[AT&T Samsung Galaxy Note 4] mcmannion:
So, it sounds like Samsung doesn't have an email address, web form, forum, etc. for enhancement requests?

On the parallel topic of big evil companies, and with respect to the folks who have offered their opinions on that subject so far, my experience has been quite the opposite - I find that most successful companies do care what their users think about their products. I work in the software industry, and the products I use most on a day-to-day basis invariably offer some sort of channel for sending feedback to the developer. Every app on the Google Play store has a "Send email" link at the bottom of it's page - in addition to many companies monitoring and responding to written feedback in the ratings section. QuickBooks has a "Send Feedback Online" option under the help menu - and even offers different options for sending comments onenhancements, bugs, and doc. A large software company that I used to work for recently implemented a suggestions forum where users can vote on enhancements, actively prioritizes work on new releases based on this feedback, and publicizes the heck out of the results in conferences, doc, and webinars. Every year I see literally thousands of people give standing ovations at one of their conferences because the developer added better Excel integration, or trimmed two clicks from a common workflow. Perhaps the best example is Atlassian, whose products many in these forums no doubt use. They are laser-focused on the people who use their tools - developers - and have been extremely successful at growing into small and large companies alike by inspiring grass roots adoption.

The list goes on. From what I've seen, companies who listen to their users do well as a result.

That said, not every company is as open to feedback as the ones in the examples above. I've found it difficult to provide feedback to Microsoft, for instance, without being part of a beta program. That said, they have robust forums that are well-attended by their internal staff. I can't say for sure, but I have to assume that the most common squeaky wheels get at least I little grease in future releases.

I don't know Samsung very well, which is why I'm asking about feedback options. It would seem odd to me that they don't have some way for users to weigh in on their Android implementation. Collectively, we buy new phones too frequently and switch vendors too easily for them not to care what we think. I like my Samsung phone, but not because it's a Samsung - it just has the features that I want. They obviously do their research into what's likely to sell. I'm hoping that there's some channel where they're actively soliciting input for improvements.

Like spexwood said, I'm not going to waste my time sending a letter to the president of Samsung and get some generic form letter in return. I know that that doesn't work. I also don't expect that Samsung will care about my suggestions, per se, even if they do have some feedback form. But, I'm sure I'm not the only one who misses text messages because the !@#$ing notification beep doesn't fire when a thread is already on the screen (for example), so if mine is one of 10K voices complaining of the same thing, it would behoove them to listen - or maybe next time I'll switch to that nice LG G3 that I almost bought instead of this Note 4.

Anyway, I'm still interested in practical options for sending OS-related feedback to Samsung. Otherwise, I can just rant about stuff xda-developers and hope that someone at Samsung is watching.
