Samsung Galaxy S4 / BMW 5 Series

Holder is quite stable and my Samsung also fits well purely without wobbling. Chess point here is the attachment to the ventilation slots. In my BMW, the holder does not fit between the vents, but is hooked to a lamella.
I hope you can see it well in the pictures.

To take the phone out of the holder's right push button to release the clips. Below on the bracket are two-webs can show came that the phone can not slip down.
The included charging cable is quite short, but depending on where the 12V supply, it may or may not be enough.

From me, there are only three stars because I think this is the bracket do not fit anywhere.
