Is it a design flaw or user error? There's a new hullabaloo over the stylus on Samsung's brand new Galaxy Note 5, as first noticed by an Android Centralforum user. Up until now, every previous Note model was designed so that the stylus couldn't be inserted blunt-end first. However, the Note 5's pen goes in either way, and doing it wrong could have dire consequences. The original poster, "FrogVomit," said that "there was no forcing whatsoever" when he accidentally inserted the pen blunt-end first, though he had to pull hard to get it back out. The result? The pen removal detection broke permanently.
