How Do I Enable Hermes on Android?

If you are an Android user, you may have come across the term “Hermes” while exploring your device’s settings. Hermes is a feature that can significantly improve the performance of your device. It is a JavaScript engine that replaces the default engine used by Android’s WebView component.

Enabling Hermes on your Android device can help speed up web browsing and improve the performance of apps that use web technologies, such as hybrid apps. In this tutorial, we will guide you through the process of enabling Hermes on your Android device.

Step 1: Check Your Android Version

Step 2: Enable Developer Options

To enable Hermes, you need to first enable Developer Options on your device. To do so, go to Settings > About Phone and tap on “Build Number” seven times in quick succession. You will see a message confirming that Developer Options have been enabled.

Note: Enabling Developer Options gives you access to advanced settings and features that can potentially harm your device if not used correctly. Be careful when making changes in this section and only make changes if you know what they do.
