Can I surf the Internet when my mobile phone thunders?

You can surf the Internet. For everyday smart phones, it is almost impossible to increase the probability of lightning strike.

The size of the mobile phone is too small, which has little effect on the resistance change. Mythbusters, a famous American program, has done experiments to test lightning strikes. Among them, the experimental data clearly shows that "playing mobile phone in rainy days" will not increase the probability of lightning strike.
