Have to disagree--while these are clearly examples of user errors, it is a design flaw. Design it properly and the user errors aren't even possible and nobody's having this discussion. It's the equivalent to having a poorly designed microUSB port that actually can accept the plug upside down and when that happens, the port break and becomes unusable.
Another member made a great point over in the Note 5 thread I believe---what if you gave your Note 5 to your kid to use for a minute? While
most adults clearly understand the mechanics of the S-Pen, it would be quite believable for a child to insert it incorrectly.
Or what if you were showing something on your Note to another adult who had never used one before--I could see my mom (not that tech savvy) inserting it upside down on accident. And also, previous versions of the Note actually gave a warning to notify the user if they were inserting it incorrectly and according to the article I linked below, the stylus couldn't actually be inserted backwards in previous Notes--why would Samsung remove this feature?
This article is clearly from a source that isn't 'an iPhone fan still butt hurt over "bendgate"' and for the most part, they agree that Samsung hasn't taken appropriate measures.
And mattopotomus posted this video in the Note 5 thread as well. Clearly, Leo's a bit of an idiot for actually do it himself but the important elements that I at least took away from it:
1) It appears to be quite easy to insert it incorrectly, meaning there's no physical resistance or indication that it's backwards
2) Samsungs official solution is 'Read the Manual'. That's just as ridiculous as Steve Jobs saying 'You're holding it wrong.'
