Automatically exit the missed calls interface.

### Your use case

#### What would you like to do?
a) If you miss a call in the lock screen state, the missed call interface should return to the lock screen after a period of time when the dialog box pops up.
b) If you miss a call while operating the phone, the missed call interface should return to the previous level after a period of time when the dialog box pops up.
c) Call the other party but the other party does not answer, the call interface should return to the previous level after a period of time when the dialog box pops up.

Such as 5 seconds.


#### Why would you like to do it?
Avoid power consumption and screen life degradation caused by lighting the screen for a long time.

#### How would you like to achieve it?
n/a

### Have you considered any alternatives?

Automated tools like Tasker or MacroDroid that detect what's on the screen and automatically act accordingly.

### Additional context

Automation tools have problems with "failure to trigger", "repeated triggers cause script errors" and "extra power consumption", which is an overkill.

### Are you willing to provide a PR?
