After Tianyu's mobile phone locks the screen, there will be text messages. What happened?

According to your requirements, the SMS will appear after Tianyu mobile phone locks the screen because the user has turned on the screen locking information function and added it to the screen locking interface, which belongs to the user's personal operation and is a normal phenomenon. If you need to cancel this function, you can slide down the display bar of SMS in the lock screen interface of the mobile phone, and the content of SMS will be displayed on the whole screen of the lock screen interface. Press and hold the content of the short message for a long time, and a deletion prompt will pop up on the screen. Move the content of the short message to the display deletion place at the screen end, and then release the delete lock screen short message.

I hope the above reply is helpful to you, and thank you for your support of Tianyu products ~
