What is lightning information?

A: Lightning SMS: It is directly displayed on the mobile phone screen, which does not occupy user space and does not need to be deleted manually. If it is not saved after reading, it will be deleted automatically. Some brands of mobile phones may not support it (for example, you can't receive the SMS, the display is incorrect or you can't save it). In addition, when some mobile phones receive multiple receipts at the same time, the previous receipt may be overwritten by the latter receipt before they can be viewed.
