Why are Xiaomi phones so rubbish?

The Xiaomi 1 we bought has no choice. There are indeed many problems, which are really irreparable. Every time something goes wrong, I feel bad for the money I spent. My Xiaomi often crashes, sometimes the screen goes blank, there are some color bars when taking photos, and it flickers and the photos taken are unusable. It will be abnormal if the theme is changed. Sometimes it will shut down automatically. It will also light up automatically, and it can light up all night. Almost all problems that cannot be heard on the Internet have occurred on my mobile phone. I don’t know how to solve it. Will Xiaomi replace it easily? Unless it is a big problem, but these small problems together are bigger than the big problem, I don’t know what to do. At that time, I was very enthusiastic about Xiaomi, but in the end I found out that the praise was high and the failure was miserable. Comparatively, Xiaomi is just a high-end knockoff, so let’s be honest. It boasts a lot of powerful hardware, but why doesn’t it tell you how to solve the problem? It’s not true to say that Xiaomi is rubbish, because it was very popular at that time. But Xiaomi mobile phones really need to take customers seriously. If you make money now, if you are scolded and can't hold your head up in the future, will you still laugh? What we bought was not at a discount. The user experience is real. I hope the person in charge of Xiaomi will pay attention to it. Don't brag like that when you buy it, comparing this one to that one. In the end, you find out that it is indeed the case. You are more "feverish" than anyone else and you don't dare to play with it directly. And it has more problems than anyone else. Why! This is sad Xiaomi.

They are still talking about M1S and M2, how good they are. Isn’t it Xiaomi’s fault that M1 has so many problems?
