How to Enable JavaScript on an Android Phone or Tablet

JavaScript is enabled by default on Android Chrome - Android's most-used browser. If a site shows a blank page or "Please enable JavaScript" message, the toggle was probably turned off by an extension, a managed work profile, or a privacy app.

This guide shows the JavaScript toggle in Chrome for Android (the default), plus exact steps for Samsung Internet (the browser preinstalled on Galaxy phones), Firefox for Android, and Brave Mobile. All instructions reflect current Android browsers in 2026.

How to enable JavaScript on a Samsung Galaxy phone or tablet

First check which browser you are using. If the app is Samsung Internet, use the steps immediately below. If it is Google Chrome, use the Chrome for Android section later in this guide.

Samsung Internet

  1. Open Samsung Internet.
  2. Tap Menu (the three horizontal lines), then tap Settings.
  3. Tap Sites and downloads, then Site permissions.
  4. Turn on Allow JavaScript.
  5. Return to the affected website and reload the page.

This is a Samsung Internet setting, not an Android system-wide setting. If the switch is already on, temporarily disable a content blocker, VPN, or DNS filter and test the site again.

What Is JavaScript and Why Do I Need It?

JavaScript is a programming language that’s primarily used by web browsers to create highly dynamic and interactive interfaces that enhance user experiences.

This powerful language is a web standard that’s supported natively on most browsers across popular Android devices such as Samsung, LG, Xiaomi, ZTE, Huawei, HTC, Sony, Nokia, Google Pixel, One Plus and Motorola.

JavaScript has become integral in modern web development as most applications that make the web indispensable for modern life are developed in some form of this robust code. So, if you have disabled JavaScript on your Android Smartphone and now wish to enable it, we are here to help.

How to Enable JavaScript in Chrome for Android

The default browser on most Android phones is Chrome. Here's how to enable JavaScript:

  1. Open the Chrome app on your Android device.
  2. Tap the three-dot menu at the top-right of the screen.
  3. Tap Settings.
  4. Tap Site settings.
  5. Tap JavaScript.
  6. Toggle JavaScript on (the toggle turns blue when enabled).

Samsung Internet (Samsung Galaxy default)

If your default browser is Samsung Internet (most Galaxy phones come with this), the path is similar: Menu → Settings → Sites and downloads → Manage website data → Site permissions → JavaScript. Samsung Internet has JavaScript on by default, same as Chrome.

Firefox for Android

See Settings → Site permissions → Advanced → JavaScript. Firefox for Android does expose a per-site JavaScript permission, unlike desktop Firefox.
