Excuse me, why doesn't the mobile phone alarm clock sometimes go off?

If you use a vivo phone, you can refer to the following methods for troubleshooting:

Situation 1, the third-party alarm clock software does not ring.

It may be that the software is not running in the background, such as cleaning the background of the software, which leads to the alarm clock not ringing after it arrives.

1, enter iManager-Application Management-Permission Management-Permission-Boot-Open the corresponding software.

2. Go to Settings-Battery-Background Power Management or High Power Consumption-Find the corresponding software-Allow high power consumption in the background.

3. Enter the card-type background, slide down the software, and display the small lock sign, indicating that the application has been locked. If you slide down again, it will unlock.

Scenario 2: The holiday alarm clock doesn't go off.

It may be that the "Smart Skip Legal Holidays" switch was turned on when setting the alarm clock, so the alarm clock will not ring on holidays. If you want to ring normally on holidays, please turn off the "Smart Skip Legal Holidays" switch.

Enter the alarm clock-click any alarm clock-(more settings)-Repeat-Turn off "Smart Skip Legal Holidays".

Situation 3: the alarm clock is on, not ringing, and the alarm clock is not ringing.

Maybe the alarm clock is too small. Please try to adjust the alarm clock. Go to Settings-Sound and Vibration, and drag the scroll bar to adjust the volume of the alarm clock to a proper position.

Scene 4: The alarm clock doesn't go off.

1. When the battery of the mobile phone is low, the system can't start, so the alarm clock doesn't ring.

2. The time switch is set on the mobile phone, and the time of the mobile phone exceeds the set time of the alarm clock after it is turned on.

It may be because the system started slowly, and the alarm clock time has passed after starting, so the alarm clock didn't ring. It is suggested to set the timer before the alarm clock time (more than 10 minutes) to avoid this problem.

Enter Settings-Quick Assist/More Settings-Timed Tasks-Time On/Off, and you can set the time and date of startup/shutdown.

If the above methods are not improved after operation, it is recommended to enter vivo official website-My Online Customer Service-to input labor and consult online customer service feedback.
