Will the hacker virus on the mobile phone seriously affect the bought mobile phone? Is there any way to keep the virus from shadowing?

Hello, I would like to ask whether the hacker virus on the mobile phone will seriously affect the newly bought mobile phone. Is there any way to prevent the virus from affecting it? The hacker virus on the mobile phone will not seriously affect the newly bought mobile phone. Because the newly bought mobile phones are brand-new and the system is set by the manufacturer, there will be no problems and they are all qualified, so the hacker virus on the mobile phone will not seriously affect the newly bought mobile phones. Don't let the virus affect:

1. Turn off the garbled mobile phone. When the other party calls in, the incoming number should be displayed on the screen. If other words or strange symbols appear, do not answer or turn off the phone immediately. If you answer an incoming call, you will easily get infected with a virus, which will lead to abnormal mobile phones.

2. Pay attention to the virus that may exist in the short message. As an important way of mobile communication, sending and receiving short messages is also an important way for mobile phones to be infected with viruses. Once a mobile phone user receives a short message with a virus, the keyboard of the mobile phone will be locked after reading it, and even the SIM card of the mobile phone will be destroyed. Therefore, please don't open the MMS sent by strangers easily, let alone forward it, and delete it in time.
