So I recently upgraded from a iPhone 6 Plus to a iPhone 6s Plus. I have a Apple leather case that I've been using since I've had the 6 Plus. I read that the case should fit on the 6s Plus but it's very tight toward the bottom of the phone. Seems to not wrap around completely so there's not really a lip toward the bottom that would protect my phone if it were dropped screen face down. I was wondering if the new cases for the 6s Plus may be a little bigger and it would fit right again. I notice the case still fits my 6 Plus like it should but not the 6s Plus. I notice the new cases say they're compatible with both phones which would make sense if it was a little bigger. Any information would be much appreciated. Wondering if I should purchase a new case.
