Imperor, When I bought my last #smartphone in 2019, I got a case for it, not realizing it already came with one.
I simply decided to use the "official" case with it and keep the extra as a backup "just in case".
Last year I finally got fed up with how the first case had yellowed and just didn't look nice anymore. Got my second case on it and I have had that "new phone" feel for months now without spending or buying a new one. I might use that trick for the next phone, too.
