What developer options are and why you might need them

Developer options are hidden settings that let you access advanced features on your phone or computer — things like USB debugging, performance monitoring, animation controls, and mock location services. They are hidden by default because changing them can break your device or expose security risks if you do not know what you are doing.

You might need developer options if you are testing an app you built, debugging code on a physical device, speeding up your phone by disabling animations, or installing software outside the official app store. Once enabled, developer options stay visible in your settings until you turn them off again.

Key Takeaways

  • On Android, you enable developer options by tapping the build number seven times in the About Phone section of Settings.
  • On iPhone, developer options are called Developer Settings and are found under Settings > Privacy & Security > Developer Mode, available on iOS 16 and later.
  • On Windows, you turn on Developer Mode through Settings > System > For Developers and choose between Developer Mode or Program Developer Mode.
  • On Mac, you open Terminal and run a single command to enable the Developer Mode option in System Settings.
  • Enabling developer options does not require special permissions or administrator approval, but changing settings within them can affect performance or security.

Enabling developer options on Android

On Android phones and tablets, the process is the same across most manufacturers. Open Settings, scroll down to About Phone (or About Tablet), and find the Build Number field. Tap it seven times in quick succession. After the fourth or fifth tap, you will see a message saying you are getting close to developer mode. After the seventh tap, a notification will appear saying "You are now a developer."

Once enabled, go back to the main Settings screen. You will now see a new section called Developer Options or Developer Settings, usually near the bottom of the list. Tap it to open the full menu. Common options here include USB Debugging (which lets your computer communicate with your device over USB), Show Layout Bounds (which outlines every element on screen), and Animation Scale (which slows down or speeds up transitions).

If you cannot find the Build Number, check whether your device uses a custom Android skin. Samsung phones call it Software Information instead of About Phone, and some Chinese manufacturers hide it in different locations. A quick search for "[Your Phone Model] build number" will show you the exact path.

Enabling developer options on iPhone

iPhone developer options are only available on iOS 16 and later. Go to Settings > Privacy & Security and scroll down to find Developer Mode. Tap it and toggle the switch on. Your phone will ask you to restart — do so, and when it comes back up, you will see a Developer Mode card on your lock screen asking you to confirm. Tap it and enter your passcode.

Once confirmed, Developer Mode stays on. You can now access developer tools like Xcode over wireless connection, enable detailed logging, and use advanced debugging features. The Developer Mode toggle itself stays in Settings > Privacy & Security so you can turn it off at any time.

If you have an older iPhone running iOS 15 or earlier, developer options are not available through the Settings app. You can still use Xcode on a Mac to debug apps on your device, but you will need to connect it with a USB cable and have Xcode installed.

Enabling developer options on Windows

On Windows 10 and 11, open Settings and go to System > For Developers. You will see several options: Developer Mode, Program Developer Mode, and Device Portal. Choose Developer Mode if you plan to sideload apps (install software outside the Microsoft Store) or use advanced debugging tools. Choose Program Developer Mode if you only need to run unsigned apps without full developer features.

Toggling Developer Mode on will prompt you to confirm and may require a restart. Once enabled, you can sideload apps by dragging and dropping .appx files onto your desktop, use Windows Sandbox to test software in isolation, and access advanced performance monitoring tools.

If you see a message saying you need to enable it through Group Policy, your computer is managed by a workplace or school network. Contact your IT department — they control which settings you can change.

Enabling developer options on Mac

On Mac, enabling developer mode requires the Terminal app. Open Terminal (search for it in Spotlight or find it in Applications > Utilities) and paste this command: sudo /usr/sbin/DevToolsSecurity --enable. Press Enter and type your password when prompted. You will not see the password as you type — this is normal.

After running the command, open System Settings and go to Privacy & Security. You should now see a Developer Mode section. Toggle it on. This unlocks features like running unsigned code, using advanced debugging tools, and accessing system-level performance data.

If you do not have administrator rights on your Mac, you will not be able to run this command. Ask whoever manages your computer to enable it for you.

Common settings you will find in developer options

USB Debugging (Android) lets your computer connect to your phone and run commands through Android Debug Bridge (ADB). This is essential if you are testing an app you built or fixing problems on a device. Turn it off when you are done — leaving it on is a minor security risk.

Animation Scale (Android) lets you slow down or speed up screen transitions. Setting it to 0.5x makes your phone feel snappier; setting it to 0 disables animations entirely. This is useful for testing but can make your phone feel less polished in daily use.

Show Layout Bounds (Android) draws colored outlines around every UI element on screen. This helps you see how apps are structured and is mainly useful if you are designing or debugging interfaces.

Wireless Debugging (Android 11 and later) lets you connect to your computer over Wi-Fi instead of USB. This is more convenient but requires you to enter a pairing code the first time.

Performance Monitoring (available on most platforms) shows real-time CPU, memory, and battery usage. This helps you spot apps that are draining resources or running slowly.

Turning developer options off

On Android, go back to Settings > About Phone, tap the Build Number seven times again, and a notification will say you are no longer a developer. The Developer Options section will disappear from Settings.

On iPhone, go to Settings > Privacy & Security and toggle Developer Mode off.

On Windows, go to Settings > System > For Developers and toggle Developer Mode off.

On Mac, open Terminal and run: sudo /usr/sbin/DevToolsSecurity --disable, then toggle off Developer Mode in System Settings.

Turning off developer options does not undo any changes you made within them — if you slowed down animations, you will need to reset that setting manually before disabling developer options.

Frequently Asked Questions

Will enabling developer options slow down my device?

Simply turning on developer options does not slow anything down. However, some settings within developer options — like Show Layout Bounds or Performance Monitoring — do use extra resources. Disabling animations or enabling battery saver mode can actually make your device feel faster.

Can I break my phone by enabling developer options?

Enabling developer options itself is safe. Changing settings within them can cause problems — for example, enabling USB Debugging and then connecting to a malicious computer could expose your data, or changing system animations could make your phone unstable. If something goes wrong, you can usually fix it by resetting the specific setting or restarting your device.

Do I need developer options to sideload apps?

On Android, you need to enable Unknown Sources in Security settings, which is separate from developer options. On Windows, you need Developer Mode. On iPhone, you cannot sideload apps without using Xcode and a Mac, which requires developer mode on the Mac, not the iPhone.

What is the difference between Developer Mode and Program Developer Mode on Windows?

Developer Mode gives you everything — sideloading, Device Portal, advanced debugging, and unsigned app execution. Program Developer Mode only lets you run unsigned apps. Choose Program Developer Mode if you only need to test one specific tool and want to minimize security changes.

Can my workplace block me from enabling developer options?

On personal devices, no. On work-managed devices (phones or computers enrolled in Mobile Device Management or Group Policy), yes — your IT department controls which settings you can access. Contact them if you need developer options for work purposes.
