Having a 635 yellow who purchased another case was wrong I turned to this case. Unfortunately it does not fit my 635 yellow. Having a friend who has a black 630 (same size as a 635 level phone) his perfect fit. The conclusion is that these are the shells of the phone that define the compatibility of the article: The sober black shell comes with a 630 or 635 in the case. While my bright yellow hull must be thicker and is smooth and slippery, it does not fit ... Hope this helped!
