This is a Sandisk Express 256GB, which I bought not too long ago for my Switch Lite. It's my first time owning one ever, so I try to be super careful with it. This is basically the second time I remove it, and I try to be super gentle too when I do it, but this time I've noticed these streaks on the surface of the back. The front looks completely normal instead. Since I'm having no issues whatsoever (besides reaching the 1K vid/10K photos limit, that's on me.), can I take it as something that usually happens, and I shouldn't worry much—or would it be best if I were looking for a new one already? Thank you to whoever will kindly respond.
