Xiaomi's mobile phone receives short messages without any prompt or sound. It's not a matter of setting. Please help ~

1. Please back up data, enter recovery mode, clear cache, clear user data and clear all data. When restoring the backup, do not restore the settings and third-party security software in the mobile phone. Try to use it normally.

2. If it still doesn't work, I suggest you brush the whole package again with a line brush according to the following method. You can refer to the following brushing tutorial:

1. First, you download a MIUI line brush package suitable for your model in Xiaomi official website. This is the link:/topic-mirom.html.

2. During downloading, please back up the data, enter recovery (shutdown, press and hold the volume increase+power on key to enter recovery), and empty the cache, user data and all data. Install the computer driver and download a miflash brush tool. This is the driver installation link:/thread-504332-1-1.html.

3. After everything is ready, please use the six-line brush according to official website's brush tutorial, which is the official brush tutorial:/thread-3104435-1.html.

4. If you are not familiar with brushing, you can refer to the brushing video tutorial made of rice flour:/v _ show/id _ xnteymjq1mzi4.html.

Thank you for your support and wish you a happy life!
