LG G Pro 2 publicized its new security unlocking function Knock Code when it was released, and said that this unlocking method is safer and easier to use than Apple's fingerprint identification Touch ID. At that time, Knock Code was still the exclusive function of G Pro 2. In April, LG will upgrade the functions of G2 and G Flex, two flagship products. We are also the first to experience the charm of tapping on G2.

LG has pushed and upgraded G2. After the upgrade, G2 can use the Knock Code tap unlock function normally. Here we use a third-party ROM implementation (Feiyu 4.4.2 V3) ▼

Enter the lock screen, you can see how to select the screen lock mode, here you can choose to tap the code ▼

Set the Knock Code tapping code, up to 8 times ▼

Confirm code ▼ again

Use the normal Power key to unlock. You can see the area below where you can tap the code. Here we can enter the password we just set to unlock ▼

Of course, we can also unlock the lock screen through the set Knock Code. The following is a video demonstration of realizing Knock Code on G2:

This ROM also supports the full screen mode of specific applications. Here we set our common browser Chrome ▼

Open the browser, you can find that the virtual key is automatically hidden, and you can call the virtual key ▼ again by drawing on the bottom
