Enable Developer Options on Android – A Complete Tutorial

Why Enable Developer Options?

Developer Options is a hidden menu that gives you access to advanced system controls. Most of these settings are intended for app developers, but many are valuable for power users who want to:

• Debug apps via USB debugging
• Speed up the UI by reducing animation scales
• Keep the screen on while charging with Stay awake
• Inspect layout boundaries, show taps, or force GPU rendering
• Limit background processes to improve battery life

Because these options can affect system stability and security, it’s important to enable them carefully and understand the impact of each setting.

Step 1 – Reveal the Developer Options Menu

1. Open the Settings app on your Android device.
2. Scroll down and tap About phone (or About device on some manufacturers).
3. Locate the entry named Build number. The exact wording may vary – on Samsung it can be Software information → Build number.
4. Tap the Build number seven times. You’ll see a short toast message after each tap, such as “You are now 3 steps away from being a developer.”
   • If your device is protected by a lock screen PIN, pattern, or password, you’ll be asked to confirm it before the taps are counted.
5. After the seventh tap, a message appears: “You are now a developer!”
6. Return to the main Settings screen. You should now see a new entry called Developer options (often located just above System or About phone).

Note: On some custom Android skins (e.g., Xiaomi’s MIUI, OnePlus’s OxygenOS), the path may differ slightly, but the principle remains the same – locate the Build number and tap it repeatedly.

Step 2 – Turn Developer Options On

The newly added Developer options entry is disabled by default. To activate it:

1. Tap Developer options.
2. At the top, toggle the switch On. You’ll receive a warning about the potential risks of changing advanced settings. Confirm that you understand the warning.

Once enabled, the menu stays available until you manually disable it or perform a factory reset.

Key Settings You Can Safely Use

Below is a curated list of the most useful options for everyday users, along with brief explanations, recommended values, and potential side effects.

1. USB Debugging

• What it does: Allows a computer to communicate with your device via the Android Debug Bridge (ADB). Essential for sideloading APKs, using adb commands, or rooting.
• How to enable: Toggle USB debugging to On. A confirmation dialog will appear – accept it.
• Security tip: Keep this off when you’re not actively using ADB. If you enable it, consider enabling USB debugging (Security settings) on newer Android versions, which prompts you each time a new computer connects.

2. Stay Awake (Screen will never sleep while charging)

• What it does: Prevents the screen from turning off while the device is plugged into power. Useful for long‑duration tasks like flashing firmware or monitoring logs.
• How to enable: Toggle Stay awake to On.
• Risk: The screen staying on for extended periods can cause burn‑in on OLED displays and will increase power consumption.

3. Animation Scale Settings

Android applies three animation scales: Window animation scale, Transition animation scale, and Animator duration scale. Reducing these makes the UI feel snappier.

• Recommended values: 0.5x or Off for all three.
• How to change: Tap each option and select the desired speed.
• Impact: UI transitions become faster, but some visual cues disappear, which may be confusing for new users.

4. Force GPU Rendering

• What it does: Forces apps to use the device’s GPU for 2D drawing operations. Can improve performance on older devices with weak CPUs.
• How to enable: Toggle Force GPU rendering to On.
• Compatibility: Most modern apps already use GPU rendering. Enabling this on newer devices rarely yields a noticeable benefit and can increase battery drain.

5. Show Taps & Pointer Location

• Show taps: Displays a visual circle wherever you touch the screen. Handy for creating tutorial videos.
• Pointer location: Shows cross‑hair coordinates and motion vectors. Useful for UI debugging.
• Both options are found under Input section. Turn them on only when you need them; they add visual clutter otherwise.

6. Limit Background Processes

• What it does: Caps the number of apps that can run background services simultaneously.
• Options: “Standard limit” (default), “4 processes”, “3 processes”, “2 processes”, “1 process”.
• When to use: If you notice rapid battery drain and have many apps open, set the limit to “3 processes”.
• Drawback: Apps forced to the background may reload when you return to them, leading to a slight delay.

7. Background Check (Android 12+)

• What it does: Periodically scans installed apps for suspicious behavior.
• How to enable: Toggle Background check under the Security section.
• This feature works alongside Google Play Protect and does not replace it.

Step 3 – Using ADB Over Wi‑Fi (Optional Advanced Feature)

Once USB debugging is enabled, you can connect to your device wirelessly, which is convenient for developers who don’t want to keep a cable attached.

1. Connect your phone and computer to the same Wi‑Fi network.
2. Open a terminal on your computer and run:

   adb tcpip 5555

3. Find your device’s IP address (Settings → About phone → Status → IP address).
4. Run:

   adb connect DEVICE_IP:5555

5. If the connection succeeds, you’ll see “connected to DEVICE_IP”. You can now use adb commands without a cable.

Security warning: Keep Wi‑Fi debugging enabled only on trusted networks. Anyone on the same network could potentially gain ADB access.

Step 4 – Reverting Changes or Disabling Developer Options

If you ever need to return the device to its default state:

1. Open Settings → System → Developer options.
2. Toggle the top switch Off. A confirmation dialog appears – confirm.
3. All individual settings inside the menu will be reset to their default values.
4. To completely remove the menu, go back to Settings → About phone** and tap Build number seven times again while the toggle is off. Some OEM skins keep the entry visible but disabled.
