Android phone is not lost, but texting others for no reason. Why?

When this happens, the software in the mobile phone is usually lost. If you often use your mobile phone to surf the Internet, you are easily infected with viruses. Sometimes, when you receive bad messages, you will be infected with viruses. The consequence of the virus is that the original information or software of the mobile phone begins to be lost, crashed, and even automatically charged. Pay more attention at ordinary times and update the software in time when problems are found. If it is not a smart phone, you should go to the mobile phone shop to find professional maintenance personnel to reinstall the software. I hope I can help you!
