Developer mode on Android is a hidden settings section that allows access to advanced features of the operating system. It is designed for testing applications, debugging performance and fine-tuning the device. However, many users are not even aware of its existence, although some features (for example, accelerating animation or enabling USB debugging) can be useful even to ordinary smartphone owners.

In this article we will look in detail at how to activate developer settings on different versions of Android, what functions are hidden there and how to use them without risk to the device. You will learn not only the standard method of switching on, but also alternative methods for devices with non-standard shells (MIUI, One UI, ColorOS and others). We will also warn about potential risks and give recommendations for safe use of the mode.

Why do you need developer mode on Android?

Many people mistakenly believe that developer menu only programmers need it. In fact, there are hidden functions here that are useful for:

  • 🔧 Speed up your smartphone — you can disable transition animations, which will make the interface more responsive.
  • 📱 Debugging connections — enable USB debugging required for working with ADB, firmware via a computer or data recovery.
  • 🎮 Game optimizations — forced use of the GPU for rendering or enabling the mode Force 4x MSAA improves graphics in games.
  • 🔍 Problem diagnostics —error logs, CPU/GPU usage statistics and other tools help identify the causes of slowdowns.

However, not all functions are safe. For example, changing parameters Dalvik VM or enabling Strict Mode can lead to unstable operation of the system. Therefore, before activating any parameter, it is recommended to study its purpose.

The standard way to enable developer settings

On most devices with Android 4.2 and newer, the developer menu is hidden, but it is easy to activate via build number. The instructions are suitable for “pure” Android (Pixel, Nexus, Android One) and most proprietary shells:

  1. Open Settings → About phone (sometimes About device or Software information).
  2. Find item Build number (may be called MIUI version, Software version or similar way).
  3. Tap on it 7 times in a row. After the first 3-4 clicks, the notification “You are almost there!” will appear, and after the 7th - the message “You are became a developer! data-i="90">Settings
  4. Return to main menu Settings - a new section will appear there For developers (sometimes he hides in Advanced or System).

On some devices (for example, Xiaomi or Huawei) after activation, you may need to enter your account password or pattern key. This is a security measure that prevents accidental activation of the mode.

Alternative activation methods for different manufacturers

Some brands change the standard activation path. Here are the features for popular ones. shells:

Manufacturer Shell Inclusion features
Samsung One UI Path: Settings → Phone information → Software information → Build numberAfter activation, the developer menu appears in Settings → Developer.
Xiaomi MIUI You need to tap on MIUI version (in Settings → About phone). hidden in Settings → Advanced → For developers.
Huawei/Honor EMUI Path: Settings → About phone → Build numberAfter activation, the section appears. in Settings → System → For developers.
Oppo/Realme ColorOS Tap on ColorOS version (in Settings → About phone). developer - in Settings → Additional settings → Developer options.
⚠️ Attention: On devices Samsung c One UI 5.0+ After resetting the settings, the developer menu may disappear. You will have to re-enable it.

How to find hidden functions in the developer menu?

After activating the mode, you will see dozens of options. safe ones:

  • ⚡ USB debugging —required for connecting to ADB, flashing or restoring data. Enable only if necessary!
  • 🖥️ Do not turn off the screen —useful when watching long videos or using a navigator.
  • 🎯 Show touches —visualizes touch points (needed for recording the screen or streams).
  • 🚀 Animation of windows/transitions —setting the value 0.5x or Off speeds up the interface.
  • 🔄 Background processes — limiting the number of background applications saves battery power.

Beware of changing parameters related to:

  • 🛑 OEM unlocking —may lead to data reset or bootloader locking.
  • 🛑 Root access —violates warranty and security.
  • 🛑 Mock Location — used to deceive geolocation, but can break the operation of some applications.
💡

Before changing any settings, make a backup copy of your data. Some settings (for example, limiting background processes) can close important applications.

What to do if the developer menu disappears?

Sometimes the section disappears after a system update or resetting the settings. Here's how to return it:

  1. Repeat activation - tap 7 times on Build number again.
  2. Check the search filter - enter in the search settings "developer".
  3. Update the software —on some firmware the menu is hidden due to bugs that are fixed in new versions.
  4. Use ADB (for advanced users): 
    adb shell settings put global development_settings_enabled 1

    adb shell am start -n com.android.settings/.DevelopmentSettings

⚠️ Attention: If the developer menu does not appear after 10+ taps, your device may have modified firmware (for example, custom software. In this case, activation may require flashing.

Risks and cautions when using developer mode

Some parameters may:

  • 🔋 Increase battery consumption —for example, enabling Do not turn off the screen or HCI Bluetooth log.
  • 🛡️ Reduce security — USB debugging on public networks risks opening access to data.
  • 🔄 Cause failures - change GPU acceleration or Dalvik VM may cause reboots.

To minimize risks:

  • ✅ Disable USB debugging after use.
  • ✅ Do not change the settings, the purpose of which is unknown to you.
  • ✅ Before experiments, create a restore point (if supported).
What will happen if you reset the developer settings?

When you reset all settings (in Settings → System → Reset), the developer menu will turn off. It will have to be activated again using the build number. The parameters themselves changed in this menu will return to their default values.

Useful ADB commands for working with developer mode

If you connected the device to the computer and turned it on USB debugging, you can control some functions via ADB. Here are some useful commands:

# Enable/disable developer mode (1 - enable, 0 - disable)

adb shell settings put global development_settings_enabled 1



Set window animation scale (0.5 - acceleration)


adb shell settings put global window_animation_scale 0.5


adb shell settings put global transition_animation_scale 0.5


adb shell settings put global animator_duration_scale 0.5



Allow installation of applications from unknown sources


adb shell settings put global install_non_market_apps 1



Show FPS (frame rate) in real time


adb shell settings put global show_touches 1


adb shell settings put global pointer_location 1

To execute commands you will need:

  1. Install ADB drivers on your computer.
  2. Enable USB debugging in the developer menu.
  3. Confirm trust in the computer on the smartphone screen.
💡

ADB commands allow you to automate the setup of multiple devices or restore access to the developer menu, if it disappeared after the update.

FAQ: Frequently asked questions about developer mode

Is it possible to enable developer mode without access to the settings?

If the screen is locked or the settings are not available, you cannot activate the developer menu in the standard way. However, on some devices this can be done via Fastboot or Recovery, but this requires unlocking the bootloader and may lead to data loss. For most users, the only safe way is to unlock the device and follow the standard instructions.

Why did the developer menu disappear after updating Android?

This is due to the security policies of some manufacturers (for example, Samsung or Xiaomi). After major system updates (for example, from Android 12 to Android 13), the developer menu may be automatically disabled. The solution is to repeat the activation via Build number.

What developer settings are safe to change to speed up the phone?

Safe parameters for optimization:

  • Reducing animation scale (window_animation_scale, transition_animation_scale) to 0.5x.
  • Limiting background processes to 2–3 (in the section Applications).
  • Enable GPU acceleration (but may increase battery consumption).

Avoid changes to Dalvik VM, Strict Mode or kernel parameters - this may lead to unstable operation.

How to disable developer mode?

There are two ways:

  1. Reset all phone settings (Settings → System → Reset).
  2. Run the command via ADB: 
    adb shell settings put global development_settings_enabled 0

After disconnecting, all changed parameters will return to default values.

Is it possible through the mode developer unlock pattern key?

No, developer mode does not provide tools for resetting the screen lock. To unlock you will need:

  • Recovery via Google account (if synchronization is enabled).
  • Reset to factory settings via Recovery (data will be available) deleted).
  • Use of specialized services (for example, Find My Device from Google).
