that's on your side, flash latest MIUI fw for you model and reflash the romFOD is still finicky for me. It usually fails recognizing my fingerprint within a split second of touching it. After touching the FOD, it registers the fingerprint just fine. I've registered my left and right thumb twice, and my index finger once. I've also tried registering my left and right thumb under minimum and max brightness to no avail.
OSS vendor means OpenSourceSoftware Vendor. This vendor is custom made and doesn't include MIUI bloats. Also, this vendor completely removes the need to flash another specific vendor for your device because it works on every model of Raphael. It is super smooth and bloat-free.
