For large smartphones inappropriate

In itself, this part is quite good, but I have it ordered for my Galaxy Note 3 and here it fails completely. The item description says that it fits for the Galaxy Note 3, which theoretically also true in practice, however, flies the spring each time out (Danger of fatal injury: the part of flying a so rapidly contrary, there is actually a risk of injury if a passrnd eye. jumps). Very annoying all, return is too annoying, everything just because the dealer / manufacturer advertises misstatement, or unrealistic.

So have the not-too-large phones for all is the part ok, owners hardly recommended for grade 3.

Edit:
Now have the spring shortened, problem holds now limited.
