I had the same issue after 1.5 years of using a Jolla C2, but I was able to open it and clean it. It seems that when using that protective case, it will take longer for it to happen, because the earpiece speaker gap has no direct contact with your pants pocket fabric and therefore prevents abrasion. But you’re right, of course it shouldn’t happen that fast. I guess there’s a missing camera ring seal.
