Sold one, kept one. Not bothering with phone cases anymore. I have a quality, translucent silicone?/ rubber? / plastic? sleeve on it to improve grip and make sure it doesn't slip off (glass-) tables. That will be recycled, and a new one bought in case of a new phone.
I'm not taking part in the race of new phones at current pace, I'm on a iPhone 6s right now ... So I couldn't use newly released cases anyway - and I won't bother with it.
Kind regards,
Oliver
