Turn on iPhone DND mode to mute notifications and incoming calls

I want to turn on iPhone do not Disturb mode to mute notifications and calls. After Cher's in-depth understanding, I got some information about the mute notification and calls on iPhone do not disturb mode. I hope it will be helpful to all of you.

However, some users find that when the mode is turned on, sound and pop-up windows still appear. How should it be set up?

Set "always" mute:

If you are still using iPhone, but do not want it to make any notification sounds, you can turn on always Mute in do not Disturb mode:

Turn on iPhone Settings-do not Disturb Mode and set Mute to always.

Screen notification message pop-up window:

If you want to focus on watching videos or playing games and don't want to be disturbed by pop-ups, you can temporarily turn off pop-up reminders in social applications, such as messages in Settings-Notification. Or try to turn on boot access mode:

Open iPhone Settings-accessibility, drop down and find guided access to open.

After starting this function, press the three-side power button in any application interface, and click "start" to enter the mode. If you are prompted to set a password, do so and set a simple password that you can remember. After the mode is successfully turned on, the screen is locked in a single application, and you can press the power button three times at any time to exit the mode (you need to enter a password or authenticate by face ID and touch ID).
