Vivo mobile phone will send messages by itself and exhale by itself. What happened?

Mobile phones automatically send text messages to make calls, which are generally caused by third-party software. Sometimes when you download some application software, it will have its own plug-in, which we can't find because it can't be seen in the mobile phone interface. Your mobile phone needs anti-plug-in software to protect your mobile phone. It is also possible that sometimes our mobile phone is in our pocket and we accidentally click the call button, which leads us to think that it was dialed automatically.

There are several solutions:

1. You should try "Settings->; More settings-> Restore factory settings-> Restore all settings ".

2. You can use "Settings->; More settings-> System upgrade-> Check the update immediately-download the upgrade package according to the system prompt, click Check and Install, and the phone will be restarted, automatically entering the upgrade mode.

3. Try "Settings->; More settings-> Restore factory settings-> Clear all data "Clear abnormal data, remember to back up in advance.
