Seems like I always have to buy a new one of these whenever I get a new phone since the new phone is always bigger than the old one. Mine is a Galaxy S8 with an aftermarket slim case. Fit is OK. Not roomy, but not too snug. I have a screen protector which can make insertion a bit tricky as it wants to stick to the clear plastic. That said, the case does what it should, protects my phone during kayaking and allows me to use the mapping function while underway.
