The mobile phone is automatically turned off after SMS poisoning.

If the phone has the following symptoms, it is likely that there is a virus in the phone. If you want to further confirm whether it is poisoned, you can use third-party antivirus software to check it.

First, the symptoms of mobile phone poisoning:

1, the phone is abnormally stuck.

When the network is normal, the mobile phone suddenly becomes very stuck, and the running speed is obviously much slower than usual. It always takes a long time to open a page, even it needs to be refreshed several times to jump out. Looking at the background data of the mobile phone, it is found that the storage space is obviously reduced, which may be that the operation of the mobile phone virus consumes a lot of storage space.

2. Inexplicable deduction

I don't know if you have paid attention to your mobile phone charges. When the mobile phone is inexplicably charged, the charge within a few days is several times the normal charge. Maybe the virus is planning something. There are two possibilities. One is a malicious charge deduction virus, which will automatically charge you if you accidentally click on a link. Another possibility is that the virus runs in the background, consuming a lot of traffic, leading to an increase in costs.

3, the power consumption speed is accelerated

In the case of the same frequency of use, the power consumption of mobile phones is faster than usual. For example, a full charge can last for a whole day, and recently it can only last for half a day. The mobile phone may already have a virus, and the mobile phone virus is operating in a black box, which leads to accelerated battery consumption.

4. The call was inexplicably interrupted

Talking to others on mobile phones often leads to inexplicable interruptions. First, check whether it's the cell phone signal and the operator's problem. If it is interrupted repeatedly afterwards, it is likely that there is a virus in the mobile phone, which will have a bad impact on the call quality.

5. inexplicable software appears on the mobile phone.

Some unknown and unheard-of software suddenly appeared on the mobile phone desktop, and various messy advertisements popped up from time to time. This is probably because mobile phones automatically download a wave of junk software when browsing informal websites, and these junk software often carries viruses.

6, the phone automatically shut down and restart.

If you are playing mobile games or chatting, the mobile phone will suddenly turn off automatically and the screen will be black. Sometimes when playing, the phone will automatically restart. If these situations happen frequently, it means that the mobile phone has been infected with a virus.

7. The mobile phone is unusually hot

Malicious viruses will bring greater burden to the performance of mobile phones. If the mobile phone runs at a low speed or is not used, it has a serious fever and feels hot, and it is likely to be infected with a virus.

8. Mobile phones often pop up yellow advertisements.

When logging in to the browser, mobile phones often pop up yellow pages and advertisements of adult websites, or often receive some yellow advertising messages with links, so it is very likely that mobile phones will be infected with viruses.

Second, the solution:

1, format the mobile phone, or restore the factory settings, so that all the data in the mobile phone can be cleared and the virus can be disposed of to a great extent.

2. If the factory settings are restored and the problem is still not solved, the machine must be refreshed. It's best to go to the mobile phone professional after-sales service center to brush the machine.
