Prerequisites Before Enabling Developer Mode
1. Check Android Version Compatibility
Make sure your device is running Android 4.1 or later. Developer Mode was made widely accessible starting from Android Jelly Bean. Although modern Android versions include it by default, the path to reach it may differ between device brands such as Samsung (One UI), Xiaomi (MIUI), Vivo (FuntouchOS), and Oppo (ColorOS). On certain phones, the Build Number field might be buried under a sub-menu, requiring an extra tap or two to locate.
Understanding where the Developer Mode settings are on your particular device ensures a smooth enabling process without confusion. If your phone is running a very old or modified version of Android, the Developer Options menu may not be available at all.
2. Secure the Device with a Lock Screen
A secure lock screen—such as a PIN, password, or pattern—is required to enable Developer Mode. This extra security step ensures that unauthorized users can’t unlock advanced settings that could alter the phone’s operation. If your device doesn’t have any screen lock set up, the system will prompt you to create one before proceeding.
This is a vital safeguard because features like OEM Unlocking or USB Debugging could be misused by someone with physical access to your device, especially if lost or stolen. Setting up a secure lock helps preserve both your privacy and the integrity of your device.
3. Understand the Potential Risks
Before enabling Developer Mode, it’s crucial to understand that many of the settings available within it can have serious effects on system behavior. For instance, turning on USB Debugging can leave your phone vulnerable to data theft if plugged into an unknown or malicious computer. Likewise, enabling OEM Unlocking allows you to unlock the bootloader, but doing so typically wipes all user data and may disable critical security features like Verified Boot.
Other settings, such as adjusting background process limits or forcing GPU rendering, might interfere with how apps normally function and could lead to performance issues or app crashes. Therefore, it’s important to use these features with caution and only after fully understanding what they do.
4. Avoid Using Managed Devices
If your phone is issued by a company, school, or government institution, it may be managed by Mobile Device Management (MDM) software. These systems often enforce policies that disable Developer Options entirely or limit their access. You might not be able to activate Developer Mode unless you remove these restrictions, which is typically not possible without administrative permissions.
If you’re unsure whether your phone is managed, check your settings under Security > Device Management or ask your IT administrator. Attempting to bypass these restrictions could violate usage agreements or even brick the device.
Step-by-Step Guide: How to Enable Developer Mode on Android
Step 1: Open the Settings App
Locate and launch the Settings app, typically represented by a gear icon. It might be pinned to your home screen or inside the app drawer. This app serves as the central hub for all your device’s configurations—from wireless connections to system-level adjustments like enabling Developer Options.
Step 2: Navigate to ‘About Phone’
Scroll down to find About Phone or About Device. On some phones, especially those running newer Android versions, you may have to go to Settings > System > About Phone. This section contains key device information like the model number, Android version, and the Build Number—your gateway to Developer Mode.
Step 3: Locate the ‘Build Number’ Field
Inside the About section, look for Build Number—a unique identifier for the system software installed on your device. On certain devices (like Samsung), you might need to first tap Software Information to find this field. Build Number is not just informational—it’s the trigger you’ll use to unlock Developer Mode.
Step 4: Tap the Build Number Seven Times
Tap the Build Number entry seven times quickly. As you tap, the system will begin counting down with a message like “You are now X steps away from being a developer.” After the seventh tap, you’ll receive a confirmation message like “Developer Mode has been enabled,” indicating success.
This secret sequence is designed to prevent casual users from stumbling into developer settings unintentionally.
Step 5: Enter Lock Screen Credentials
If your phone is protected with a PIN, pattern, or password, the system will now ask you to verify your identity. This security checkpoint ensures that only an authorized user can activate Developer Mode. Enter your credentials to proceed and finalize the activation.
How to Access Developer Options After Enabling It
Once Developer Mode is activated, the Developer Options menu will appear in the Settings app. You won’t find it under “About Phone”—instead:
- Open Settings again.
- Scroll down to System (on some devices, it appears under Additional Settings).
- Tap Developer Options to access the advanced configuration tools.
This menu stays visible until it’s disabled or hidden manually. You can revisit it anytime to enable or disable specific developer-related features.
Most Useful Features in Developer Mode
1. USB Debugging
This feature allows your Android device to communicate with your computer using Android Debug Bridge (ADB). It enables developers to push apps, inspect log files, issue commands via terminal, and debug applications in real-time. Even if you’re not a developer, USB Debugging is essential for tools like Titanium Backup, scrcpy (screen mirroring), or recovering data using PC software.
Keep in mind that while this feature is powerful, it should be turned off when not in use to avoid security vulnerabilities.
2. OEM Unlocking
Enabling this option allows the bootloader to be unlocked—a necessary step if you want to root your device or install custom firmware like LineageOS. Once the bootloader is unlocked, you can flash third-party ROMs or recovery tools such as TWRP.
However, this option wipes all your data, voids warranties on many devices, and disables key security features. Only enable OEM Unlocking if you know exactly what you’re doing.
3. Stay Awake While Charging
Activating this setting prevents the screen from turning off while the device is charging. This is useful during app testing or development sessions where you need constant access to the UI. It’s also handy for kiosk setups or long monitoring sessions during system diagnostics.
4. Limit Background Processes
This option allows you to limit how many apps can run in the background simultaneously. It helps conserve RAM, CPU, and battery life, especially on older or less powerful devices. Setting a lower background process limit can improve performance during heavy multitasking but may cause certain background-dependent apps (like music or messaging apps) to misbehave.
5. Animation Scales (Window, Transition, Animator)
These settings control the speed of UI animations across the device. By reducing or disabling the Window Animation Scale, Transition Animation Scale, and Animator Duration Scale, you can make your phone feel significantly faster and more responsive. These settings only affect perception, not real speed, but the effect can make the phone seem snappier in daily use.
6. Show Taps and Pointer Location
This is especially helpful for developers creating tutorials, app demonstrations, or UI testing. Show Taps displays a visual indicator wherever the screen is touched, and Pointer Location overlays crosshairs and touch coordinates, providing granular input tracking. These tools are also useful for diagnosing touchscreen issues or showcasing interactions during screen recordings.
How to Disable or Hide Developer Mode
Option 1: Disable Developer Options Manually
Go to Settings > Developer Options and toggle the switch at the top to Off. This deactivates all developer tools while keeping the menu available for future use. It’s the safest way to temporarily stop using advanced features.
Option 2: Completely Hide Developer Mode
If you want to remove the Developer Options menu altogether:
- Go to Settings > Apps > Settings > Storage
- Tap Clear Data
This will reset all system settings (excluding your personal data) and remove the Developer Options menu from visibility. To use it again, you’ll need to re-enable it by tapping the Build Number seven times.
