Apple ipad lights up when it receives a message.

The reason why iPad lights up when it doesn't receive information is because users are allowed to lock the screen when setting up, so just turn it off.

The closing method is: click Settings to find the notification option, and then click the notification option. At this time, we can see that there is a list of notification styles under the notification option, including each APP. At this point, we can find the application that we want to turn off the reminder message. After being selected, you will see three reminding methods: lock screen, notification center and banner. We just need to cancel the lock screen, and the notification message of the APP will not be displayed on the lock screen, nor will it be displayed.
