Excuse me, I just bought Xiaomi 3 a month ago. Why am I texting now? I can't send it. What happened?

Please try it according to the following two points:

1. Please back up the data first (create a new backup by opening the system and security ~ backup ~. ), then, enter the recovery mode, clear the cache, clear the user data, clear all data, and do not restore the settings and third-party security software in the mobile phone when restoring the backup. 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:

A. First, you download a MIUI line brush package suitable for your model in Xiaomi official website. This is the link:/thread-504332-1-1.html.
