The Apple clear case doesn’t yellow, but the buttons are hard to push and the bottom of the phone isn’t protected. I just got my rhino shield clear case today and it seems pretty good, it’s supposed to not yellow as well. The buttons are satisfying and clicky, the only bad thing so far is that it is kind of a pain to take off. My phone went into SOS mode and called emergency service 3 times trying to take the case off lol, so I would turn the phone off if you remove the case. But other than that it’s great so far.
