Mobile phones often receive multimedia messages with strange numbers 1kb, but there is nothing after opening them. Is it a virus?

"If you need to identify whether your mobile phone has a virus, I suggest you:

1. Some mobile phones support intelligent manager (memory manager). You can scan the device through "Device Security" to detect the memory of the device and find out whether there are threats or malware on the device.

2. Download more secure mobile phone security software to scan your mobile phone.

If the mobile phone detects a virus, it is recommended that you:

1. Back up important data (contacts, photos, memos, etc.). ) and restore the factory settings.

2. If the above operation fails, please bring the purchase invoice, maintenance card and machine to the service center for inspection. "
