Why did the mobile phone crash when it received a short message? How to solve this problem?

This short message has JS code in it. The way is to copy it quickly as soon as it is opened. This code is that the system memory stack of the mobile phone crashes when it goes wrong. The only way is to unplug the battery. I suggest you try to delete it without opening it as soon as possible, otherwise unplugging the battery without turning it off will hurt the mobile phone.
