Mobile phone text messages or phone calls have radiation, why is the computer monitor black screen or flower screen?

This is so-called electromagnetic interference ~

It means that your monitor is poorly made and shielded. Or the radiation of mobile phones far exceeds the national standard. (with all due respect, it really is)

In the first case, I suggest that the monitor can make do with it and put away the mobile phone if there is nothing.

In the second case, I suggest changing the mobile phone. In particular, it is a miscellaneous brand. Although it is cheaper, eating too much electromagnetic radiation is not good for your health. But you throw watermelons and pick sesame seeds.
