Xiaomi's mobile phone doesn't prompt for text messages.

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 bag with a line brush in the following way. 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. The link is as follows:/topic-mirom.html.

2. During downloading, please back up the data and enter recovery (power off, press and hold the volume increase+power on key to enter recovery) to clear the cache, clear the user data and clear 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 sixth brush according to official website's brushing tutorial, which is the official brushing tutorial:/thread-3104435-1.html.

4. If you are not familiar with brushing, please 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!
