Sorta.... When I first got my R4, putting in the microSD would result in a very loud click. It worked that way for about a week. After that, the click got very faint sounding and i had to fiddle with it to make the microSD stay in. I found that if I hold the sides of the casing around the microSD slot as I insert the card, it will still make a louder (but not as loud as when I first got it) click and still hold the microSD. I've been using that method ever since without issue. Sometimes I can put the microSD in with the R4 still in the DS slot and sometimes it makes me do as I described in the previous paragraph. I just wish there was a surefire way to fix it without removing the spring.....make it click loudly like it did when I first got it. Meanwhile, my SCminiSD's SD slot still works as well as the day I got it. And I bought it a couple months before the R4.
