5 hidden functions of the phone volume keys

What are the volume keys of the phone for? Many people's first reaction must be to adjust the volume of ah. But in fact, the role of the volume key is much more than that, it also has these 5 functions.

 

1. Screen off fast call

 

In fact, you can press and hold the volume key and say the name of the person you want to call after you hear the "drop" sound, so you can make a call directly without unlocking the screen.

 

The prerequisite for using off-screen quick call is that you need to open this feature yourself: for Android phones, Huawei, for example, open Settings - Smart Assist - Voice Control, then turn on an off-screen quick call, and use it in the lock screen by simply pressing and holding the volume - key.

 

iPhone X and above, open settings - auxiliary functions, then find the side button and click on the classic voice control. After setting, long press the right side button key to say call so-and-so. The biggest difference between classic voice control and Siri is that it does not need to connect to the network faster response time, and it will not upload your data. For an old iPhone with a home button, open Settings - General - Accessibility, find the home button, click Voice Control, and long press the Home button in the lock screen state.

 

2. Quick mute

 

When the phone rings during a meeting or while driving, but it is not convenient to hang up, you just need to press any volume key and the phone will be silenced immediately. This function is also applicable to the phone alarm clock, want to sleep again can be pressed, but we recommend that you use caution, and be careful to be late for work.

 

3. Phone photo

 

This function is similar to the fast mute, click on any volume key when taking pictures, especially when taking selfies is particularly useful.

 

4. Forced reboot

 

I believe that many users who have used the interface are stuck in the phone does not respond to the situation, this time there is no way to shut down the phone, you can use the volume keys to force a restart. Most Android phones long press the lock screen key for 10 seconds, until the phone automatically shut down, and the screen black screen can release the power button.

 

iPhone 6 and the following older models press and hold the lock button and Home button at the same time, when the Apple logo appears, release both buttons at the same time. iPhone 7 series press and hold the volume key and lock button at the same time, when the Apple logo appears, release both buttons at the same time. iPhone 8 and subsequent models press the volume + key and release quickly, press the volume key and release quickly, then press and hold the lock button Release until the black screen, then wait for a reboot.

 

5. Turn off the torch

 

This feature is currently only available on Huawei phones, you need to open the camera in the off-screen snapshot, in the off-screen state two clicks of the volume-key phone flashlight will be closed.
