Why is Xiaomi mobile phone so rubbish?

We bought Xiaomi 1, but there was nothing we could do. There are indeed many problems, which are really irreparable. Every time something goes wrong, I feel bad about the money I spent. My millet often crashes, sometimes the screen will be blank, some colored bars will appear when taking pictures, and even the flashing photos will not be used. It's not normal to change the theme. Sometimes it closes automatically. It will also light up automatically and it will light up all night. I can't hear it online. Almost all my mobile phones have appeared. I don't know how to solve it. Will Xiaomi change easily? Unless it is a big problem, these small problems add up to bigger problems, and I don't know what to do. At that time, I was very enthusiastic about holding Xiaomi, and finally found that it was very bad. Compared with Xiaomi, it is a high-grade cottage. To tell the truth, the hardware is much better, but why not talk about how to solve the problem? At that time, it was not true that Xiaomi garbage was popular, but Xiaomi mobile phone really needed to take customers seriously. Now it makes money, and you will be embarrassed in the future. Can you still laugh? We are not buying discounted goods, and the user experience is real. I hope that the person in charge of Xiaomi Company can pay attention to it. Don't blow like that when you buy it. Better than this cow. Finally, I found that it was "feverish" than anyone else, and you were afraid to play directly. And there are more problems than anyone else. Hey! This is pathetic Xiaomi. Actually, it's M 1S, M2. No matter how good M 1 so many problems, isn't it Xiaomi's fault?
