To turn on Developer Options on most Android phones, you use a hidden “build number” shortcut in Settings.

Quick Scoop: Fast Step‑By‑Step

  1. Open the Settings app on your Android phone.
  1. Scroll down and tap About phone (sometimes under System → About phone).
  1. Find Build number (you may need to tap Software information first on some phones like Samsung).
  1. Tap Build number 7 times quickly.
 * You’ll usually see a small countdown like “You are 3 steps away from being a developer.”
  1. If asked, enter your PIN, pattern, or password.
  1. You’ll get a message like “You are now a developer!”.

Now Developer Options are unlocked.

Where Developer Options Show Up

Once enabled, the new menu doesn’t pop up on your home screen; it lives inside Settings.

  • On many phones: Settings → System → Developer options.
  • On some devices (including several Samsung models): Settings → Developer options at the bottom of the main Settings list.

Open that menu and you’ll see advanced tools like USB debugging , animation scales , and more.

How to Turn Developer Options Off Again

If you were just testing something, you can easily switch it off.

  • Go to Settings → System → Developer options (or Settings → Developer options).
  • Toggle the main Developer options switch at the top Off.

On many phones, this disables all those settings and hides the menu again from the main Settings list.

A Few Popular Things People Use It For

Once Developer Options are on, typical users play with just a handful of settings.

  • USB debugging – needed for many desktop tools and developer workflows.
  • Animation scale tweaks – speeding up or slowing down window and transition animations to make the phone feel snappier or to test performance.
  • Quick settings developer tiles – adding special tiles to the Quick Settings panel for faster access to certain dev functions.

Note: It’s generally safe to enable Developer Options, but changing random toggles inside can cause odd behavior; stick to options you understand or can easily reset.

TL;DR: Go to Settings → About phone → tap Build number 7 times → enter PIN → Developer Options appears in Settings (often under System).
