mi5 is the pure flagship and more popular, 5s is just something between mi5 and mi6.But that SD821 models are more recent than MI5 and they are flagships too (I think), the updates should follow a kind of order. I think its funny because Xiaomi updates the phones some kind a "randomly", and some models are always behind (like Mi5s), Mi Note 3 is also behind Mi5 and its a newer phone that should be updated first... (Experts say that is the the best Xiaomi camera ever on a phone). However this week rom on my mi5s its awesome! Everything works as it should! Keep the good job @ingbrzy and all the comunity.
Yes, in mido was removed, to bad@ingbrzy, did you remove this option on purpose in latest build? its about security code/pattern, you cant make it optional now while unlocking the phone. you have to swipe + write a code/pattern to unlock phone, whereas earlier you could juat stay with swipe, even if the code/pattern was active (its required when you activate fingeprints)
