The mobile phone purchased at 2898 yuan in 2020 is equipped with 12GB RAM and 128GB storage capacity. After one year of initial use, a series of problems occurred after the warranty period ended. The mobile phone will automatically shut down from time to time. After taking it to the mobile phone store for maintenance, it was told that it was a problem of CPU faulty soldering, which cost 300 yuan to repair. Unfortunately, however, the problem reappeared a week after it was fixed. At that time, I was on a business trip and had to send my mobile phone to the local mobile phone repair shop again. This repair cost 280 yuan.
Half a year later, it became difficult to charge the mobile phone, which was very frustrating. I spent another sum of money to repair the CPU, and then the problem was solved. But a month later, when I tried to connect my mobile phone to the computer to read data, I found that I could only charge, but could not transmit data. This problem makes me feel very troubled.
One year later, the rear camera suddenly failed to open normally. I even tried to buy a new camera component, but still couldn't solve the problem. After checking, the maintenance technician told me that there was a connection problem between the rear camera and the CPU, and the CPU needs to be repaired again. I'm C! I mentioned to the maintenance technician that I have repaired this phone many times and need to repair the CPU every time. Shifu told me that some models of Xiaomi mobile phones equipped with Snapdragon CPUs have this problem, because excessive temperature may lead to faulty soldering. He asked me if I often played games while charging, and I replied that no, I just used my mobile phone lightly.
Talk about the advantages of mobile phones!
The original cost performance ratio was very high! Another full screen phone.
The BL lock is released, and the MIUI11 version shipped from the factory is still smooth!
I still hope that Xiaomi's mobile phone can be better and better, and more efforts should be made to check the quality control problems. Xiaomi's mobile phone configuration is OK, so strengthen quality control!
Since the first problem occurred, I have bought a fruit 12 as the main machine. The stability is OK, but the battery is not good. The stability of 6, 6s, 7, X, and XS that have used fruit is very good. They were released on the 15th of yesterday! After watching the press conference, I was really disappointed with Apple and didn't look forward to it! What things have been updated
