There are several ways to lock the screen on Huawei mobile phones

1. Generally, Huawei mobile phones have four unlocking methods, including number, pattern, fingerprint and face unlocking.

2. After entering Security and Privacy, there is also Privacy Space and App Lock. You can set an independent password in the privacy space. After entering, it will be a brand new system where you can store your own "little secrets". After App Lock is turned on, you can lock apps that you don’t want others to see, such as photo albums, text messages, WeChat, etc.

3. Regardless of whether you set a face or fingerprint lock, you need to set one of the following three locks before you can continue.

To unlock the pattern, connect at least 4 dots. As long as one dot is not repeated (can cross), you can draw it in one way, as long as you remember it. What kind of complicated pattern locks have you set up? (Most people will set Z, 7 or N) Welcome to discuss the picture.

4. Be sure to remember the password you set. If you forget it, you cannot retrieve it. You can only restore the factory settings and everything will be lost. Restart or do not enter the password for three days to unlock. Even if the face or fingerprint is set, the phone cannot be unlocked. Special reminder: Never set a password after drinking or before going to bed.

TIPS: Some mobile phones with new systems default to six digits. To switch back to four digits, just click on the Select other password option below the password input box to switch to 4 digits. When switching to a complex password, you can also enter alphanumeric characters as the password. No one else can guess it. You have to remember it yourself.

5. The next step is to rely on your face. Face unlocking may be unlocked by people or items with similar appearance. This means twins should be able to unlock each other. Security is not as secure as numbers and fingerprints. After all, looks are not unique, but fingerprints are. Cannot be unlocked with eyes closed. You don’t have to worry about being unlocked and peeking at your phone when you’re asleep

5.1 Face recording should be done in a place with sufficient lighting and where the camera’s facial features are clean and unobstructed. After logging in, face unlock can be performed.

Here comes the key point: Do you see the lift-up screen at the bottom? After turning on the switch, if the face recognition is successful and the screen is raised, the screen will be unlocked. Some people don't like this, saying that it's inconvenient to unlock it if you don't want to collect it, but just want to check the time. In fact, you only need to close the screen and lift it up to turn on the screen. If you need to unlock it, press the lock screen button (power button) to turn on the screen. It seems inconvenient. It will still unlock when you see a face when the screen is turned on

5.2 When registering a face, if you point it at other objects, it will prompt that the face registration failed. So it is impossible to unlock it by relying on the cat's face.

6. Lift up to brighten the screen. As mentioned just now, it actually has other functions. It can lift up to weaken ringtones, alarm clocks, etc. Some Huawei phones also have a flip-to-mute function. Turn the phone upside down to mute the alarm clock and incoming call ringtones. It is easier to use in meetings or when it is inconvenient.
