While the Redmi Note 4 does not support direct voice command unlocking, you can still achieve a similar effect using workarounds and third-party solutions. In this guide, we will explore the best methods to integrate voice commands for unlocking your device without compromising security.

Introduction

The ability to use voice commands for device unlocking has become a popular feature among smartphone users. Although the Redmi Note 4 natively does not support voice commands for locking and unlocking, you can still leverage existing third-party services and features to achieve a similar functionality. We will explore two primary methods: using Google Assistant and utilizing Smart Lock. Additionally, we will discuss the limitations and security risks involved in these methods.

Method 1: Use Google Assistant

Step 1: Set Up Google Assistant

Step 2: Voice Match

For better accuracy, set up a voice match with Google Assistant:

Step 3: Unlocking via Google Assistant

With Google Assistant set up, you can request it to perform certain tasks or answer questions while the phone is locked:

Limitations and Security Risks

While these methods offer a semblance of voice command unlocking, there are several limitations and security risks to consider:

Security Risks

Using voice commands for unlocking can pose security risks as anyone who can mimic your voice may gain access. Additionally, the effectiveness of voice recognition may vary based on background noise and the clarity of your voice.

Alternatives and Custom ROMs

For a more seamless experience, some users might consider flashing custom ROMs like LineageOS 15.1. However, this is not recommended unless you are familiar with the process:

Flash custom ROMs like LineageOS 15.1 for the Redmi Note 4. Be cautious as flashing custom ROMs can void the warranty and may brick your device if something goes wrong.

Conclusion

While the Redmi Note 4 does not natively support voice command unlocking, you can still use Google Assistant and Smart Lock to achieve a similar effect. However, always be aware of the limitations and security risks involved. If you are comfortable with custom ROMs, that might offer a more integrated solution.
