Why didn't the phone remind you?

Because you set the "Do Not Disturb" mode.

The solution steps are as follows:

1. As shown in the figure below, you can set "Do Not Disturb" under the "Settings" menu of your mobile phone.

2. Click the "Settings" menu, find "Do Not Disturb", click to enter the "Do Not Disturb" interface, and you can set it!

3. Next, I will introduce the situation of being blacked out. After blacking out some numbers (adding to the blacklist), when the other party calls, the phone always prompts that it is on the phone. As long as this phone number is removed from the blacklist, the problem will be solved.

Do not disturb is a mobile phone security software, which is suitable for Android2.2 and above systems. If you don't want your mobile phone to ring during important meetings or at night, this is a program for you. In addition to disabling ringtones, this will suppress other sounds. It can turn off events on the phone calendar.

This application will not affect the battery performance of the mobile phone.

Starting from the iOS 6 system, Apple has added the function of "Do Not Disturb Mode" to the iPhone and iPad, which has never been seen before.
