I’m using the official transparent case for the Phone (3a) (likely the same as the official case for Phone (3)) and it’s doing pretty well. No yellowing so far, but it does get micro-scratches that are visible in certain light. There’s a noticeable scratch from concrete, but the phone itself is fine. It can scrape on rough surfaces, and it smudges easily which is the tiniest bit annoying, but that’s a minor issue.
