In 2014, LG introduced a unique feature for its smartphones called “Knock Code.” This feature was designed to offer users a more personalized and secure way to unlock their phones, providing a modern alternative to traditional unlocking methods.
What is Knock Code?
Knock Code is a proprietary software feature integrated into LG smartphones. It replaces conventional screen unlocking methods, such as pressing the power button or entering a PIN, with a customizable tapping sequence on specific areas of the screen. Users can set their own unlock sequence by selecting areas on the screen and tapping them in a specific order. To unlock the phone, the user taps on these pre-set areas in the correct sequence. The number of taps can range from 2 to 8, offering flexibility in the complexity of the unlock pattern.
This method makes unlocking the phone more interactive and adds a layer of personalization and security.
Convenience vs. Cumbersome?
While LG marketed Knock Code as a convenient feature, its practicality is subjective. Some users find the tapping process intuitive and fun, as it eliminates the need for physical buttons. However, others may feel that repeatedly tapping the screen—especially up to 8 times—can be cumbersome, especially when compared to simpler unlocking methods, like pressing a power button or using a fingerprint scanner.
How Does Knock Code Compare to Other Unlocking Methods?
Knock Code isn’t entirely unique in smartphone security. It shares similarities with graphical unlock patterns used by other manufacturers, where users connect dots in a specific sequence to unlock their devices. However, there are key differences:
- Screen Division: Knock Code divides the screen into multiple areas, allowing users to set tap patterns within these zones.
- Minimalist Interface: Unlike graphical patterns, Knock Code doesn’t display visible guides, making it more secure as it is harder for unauthorized users to guess the sequence.
Advantages of Knock Code
- Enhanced Security: With no visible prompts, Knock Code makes it more difficult for someone to replicate the pattern by observing the user.
- Customizable Complexity: The option to choose between 2 to 8 taps allows users to find a balance between convenience and security.
- No Physical Buttons: Knock Code eliminates the need to press physical buttons, which can wear out over time.
Drawbacks of Knock Code
Outdated Technology: As newer biometric technologies like fingerprint and facial recognition become more common, features like Knock Code might seem less relevant to some users.
Learning Curve: Some users may find the tapping process confusing, especially if they are used to traditional unlocking methods.
Excessive Tapping: Tapping up to 8 times might feel excessive compared to simpler unlocking methods like fingerprint scanning.
