How does Apple record videos on a black screen?

First, let's talk about Apple's mobile phone. What can Apple phones do on the screen?

1, information screen video

First, screen recording. Click Settings-General-Accessibility-Zoom. A rectangular border will appear. Click the bar at the bottom of the border, and then click to select Low Light Filter.

Go back and click full-screen zoom to minimize the progress bar below. Quit zooming, click the accessibility shortcut key, select zooming, and do not select other options.

Then slide the screen to the left with the screen locked, slide a large part but don't let go, as shown in the figure, then click the video recording function and press the Home button three times in a row. If the screen brightness becomes dim, you can record video. But if you want to stop recording, you need to unlock the screen.

2. Breathing screen weather

If you want to broadcast the weather by voice in the interest status screen, you can set it like this:

Click Settings-Privacy-Location Services-Weather-Always.

Then, in Siri settings, open the shortcut command of weather, and check Allow lock screen display. This will automatically broadcast the weather when the alarm clock rings every morning.

3. Information screen clock

IOS 12 also has a bedtime function in its built-in clock. We can set the sleep time, so that when the alarm goes off every day, the screen lock interface will also show the time.

4, interest screen alarm

In addition, there is a life-saving function in the Apple mobile phone! Although I hope everyone will never use it, it is best for everyone to open it.

Click Settings -SOS Emergency Contact-Add Emergency Contact, and then turn on automatic calling, so that in case of emergency, you can call for help quickly by pressing the power button five times!
