Hey guys i was just doing an experiment to see if the miui camera and gallery work on a rooted d3. Turns out they do with almost no problems. I say almost because it looks like the camera app may have a few issues but im sure that has something to do with it being a hardware issue.
All I did was download the apks and place them in /system/app named Miuicamera.apk and Miuigallery.apk
The camera also is a lot faster then default. So that's something to check out
