Why doesn't the mobile phone alarm clock ring sometimes?

If you use a vivo phone and the alarm clock doesn't go off, you can solve it like this:

First, the use of 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. Go to Settings-Applications and Permissions-Permissions Management-Permissions-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.

Second, the holiday alarm clock doesn't go off.

It may be that when setting the alarm clock, the "Smart Skip Legal Holidays" switch is turned on, 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.

Third, the alarm clock does not ring when it is turned on, and the alarm clock does not ring.

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.

Fourth, turn off the alarm clock that doesn't ring.

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.
