Hi, I'm a new owner of a beautiful xiaomi mi2s and i'm starting to understand how it works. I'd like to have some answers to questions i made myself, cause i'm willing to understand better my phone . 1) How do system 1 and 2 work? I mean i noticed that installing same rom on both, every change i make on one i see on the other. Shouldn't they be separated or something like that? 2) Just for curiosity, how could i remove system apps? I thought i had root permissions, but seems that i still can't. 3) I have a problem with contact syncro. I saved some contact in my xiaomi account. Then i imported some other from google account and joined both. But even thoug syncro is activated i can't see any change in xiaomi account ( i mean on i.xiaomi.com), while if i modify or add a new account, i can see the change on the account. Why?
