As you know xiaomi is a china company its andriod system is marshmellow it might be nougat or oreo. china is not as trusted as others. camera instead of 13mp picture quality is not as good as others if you dont belive you buy but if you have time to kill, buy it .once I saw friend phone but I dislike its camera so I chek it and it is not so trusted. it is a company of good selling in here but after. buying you can get it
