Developer options on Android: how to enable and why you need it

Hidden Developer options in Android provide access to dozens of additional functions that manufacturers usually hide from the average user. This isn't just a "secret menu" for programmers - it can speed up interface animations, debug applications, enable USB debugging, or even simulate a secondary display. But how to get there if the item is not in the standard settings?

Enabling this mode takes less than a minute, but requires knowledge of the “secret code” - a combination of clicks in the menu About the phone. The procedure is the same for most devices based on Android 5.0 and newer, but there are nuances for smartphones Samsung, Xiaomi or Huawei. In this article, we will analyze all the activation methods, tell you which settings should be changed first, and which ones are not recommended to be touched. And yes, on some devices, after resetting to factory settings, the developer options are automatically disabled - you will have to enable them again.

Why do we need developer options?

Most users do not even suspect that their smartphone can do much more than what is shown in standard menu. Developer mode (Developer Options) was originally created for testing applications, but over time it has turned into a powerful tool for fine-tuning the system. Here's what you can do with it:

• ⚡ Speed up the interface - disable or reduce the animation of windows, transitions and animators (this really makes the smartphone "faster" to the eye).
• 🔌 Enable USB debugging - without this it is impossible to connect to Android Studio, flash the device via fastboot or use ADB.
• 📱 Simulate a secondary display —useful for streamers or those who connect a smartphone to a monitor.
• 🛠️ Force applications to run in the background —even if the system “puts them to sleep” to save money charge.
• 📡 Change data transfer standard —for example, force turn on LTE instead of 5Gif the connection is unstable.

But there is also a downside: careless changes can lead to deterioration of performance, increased battery consumption or even unstable system operation. For example, if you turn on Do not turn off the screen during charging, the display will remain on constantly - this will shorten the life of the matrix. And activation GPU acceleration for all applications can cause graphic artifacts.

⚠️ Attention: On devices with Android 12 and newer, some developer options may be blocked by the manufacturer. For example, Samsung restricts access to settings OEM Unlock (unlocking the bootloader) through the security policy.

The standard way to turn it on on most Android devices

The instructions are suitable for “clean” Android (for example, on smartphones Google Pixel, Nokia, Motorola) and most devices of other brands. The main condition is that the system version is not lower Android 4.2 (released in 2012). If you have an older firmware, update it via Settings → System → Software update.

The algorithm is simple:

1. Open the application Settings (gear icon in the menu or on the desktop).
2. Scroll down and select About phone (on some devices it may be called About tablet or Device information).
3. Find the line Build number (sometimes it is hidden in the submenu Software information or Android version).
4. Click on Build number 7 times in a row. After the first 3-4 clicks, a pop-up notification will appear: "You're almost on target!".
5. After the 7th click, the system will show the message: "You have become a developer!".

Done! Now in the main menu Settings a new item will appear - For developers (usually it is located in section System or at the end of the list). On some devices (for example, Xiaomi) this item may be called Advanced settings.

Features of enabling on smartphones Samsung, Xiaomi, Huawei and other brands

Manufacturers often modify the interface Android, so the path to the developer options may vary. Below are current instructions for popular brands (at the time of writing). If your model is not in the list, try the standard method or look for the path to Build number Manually.

Brand	Path to "Number" assembly"	Features
Samsung (One UI)	Settings → Phone information → Software information → Build number	After activation, the item will appear in Settings → Developer options. On new models, you may need to enter a PIN code.
Xiaomi (MIUI)	Settings → About phone → MIUI version (press 7 times)	The item is called Advanced settings and hidden in Settings → Advanced.
Huawei (EMUI)	Settings → About phone → Build number	Some models require you to enter your account password Huawei ID.
Realme/Oppo (ColorOS)	Settings → About phone → Software version → Build number	The item will appear in Settings → Additional settings → Developer options.
Google Pixel	Settings → About phone → Build number	The "cleanest" Android - the item will appear immediately in the main menu Settings → System.

If you did not find your model in the table, try using the search in the settings (magnifying glass icon in the upper right corner of the menu SettingsEnter). request "build number" or "build" —the system will tell you where to look.

⚠️ Attention: On devices Samsung with Android 13 and newer, the item OEM Unlock (unlock bootloader) may be hidden even after enabling developer options. To unlock it, sometimes you need to connect the device to the PC and run the command. adb shell.

Top 5 useful settings in the developer options

Now that you have activated the mode, it’s time to figure out what can and should be changed here. We have selected 5 most useful optionsthat will not harm the system, but will significantly improve the user experience. It is better not to touch the remaining settings without a clear understanding of their purpose.

• 🚀 Animation acceleration: Go to Window animation, Transition animation and Animator duration —set the value 0.5x or Off. The interface will respond instantly.
• 🔋 Background running of applications: Enable Do not limit background processesif you notice that messengers or music applications “fall asleep” when minimized.
• 📶 Forced LTE: In the section Network select Only LTEif 5G it is unstable, but your tariff supports 4G.
• 🖥️ Simulate secondary display: Activate Simulate secondary displayif you connect your smartphone to the monitor via HDMI or USB-C.
• 🔍 Error log: Enable Enable error logif you want to track application failures (useful for reporting to developers).

Here's what it is not recommended to turn it on unnecessarily:

• ❌ Do not turn off the screen - shortens the life of the matrix.
• ❌ GPU acceleration for all applications - may cause graphic glitches.
• ❌ Disable absolute volume level —disturbs the sound balance in Bluetooth headphones.

How to disable developer options

If you no longer need advanced settings or want to hide them from strangers (for example, before selling your phone), there are two ways to disable them:

1. Through the settings menu:
   1. Go to Settings → System → For Developers.
   2. At the top of the screen, find the switch Developer options and move it to Off.
2. Through a factory reset (if the first method did not work):
   1. Open Settings → System → Reset.
   2. Select Reset settings (do not confuse with Factory reset —this will delete all data!).
   3. Confirm action.

After disabling, the item For developers will disappear from the settings menu. To return it, you will have to press again Build number 7 times.

⚠️ Attention: On some devices (for example, Xiaomi s MIUI 14) resetting the settings does not remove the developer options. In this case, only a full factory reset will help, but it will delete all data from the phone!

Common problems and their solutions

Sometimes users encounter difficulties when trying to enable developer options. Here are the most common situations and ways to solve them:

• 🔄 Notification does not appear after 7 clicks:

  Check that you are clicking on Build numberand not on neighboring items. On some devices (for example, Sony Xperia), you need to click on Kernel version.

• 🔒 The "For Developers" item is gray and inactive:

  This means that the parameters are enabled, but blocked by security policy (often happens on work phones with MDM). Try disabling it through Settings → Security → Device Administrators.

• 📱 After updating Android, the settings disappeared:

  This is normal - after major system updates, some settings are reset. Just click on Build number 7 times again.

• ⚠️ Security risk warning has appeared:

  Some manufacturers (for example, Huawei) show a warning when enabling developer mode. This is not an error - just confirm the action.

If none of the methods helped, check to see if custom firmware or root accessare installed on your device. They may block access to standard settings. In this case, try returning your smartphone to the factory firmware.

What to do if developer options are not enabled on Samsung?

On devices Samsung s One UI 5.0 and later, additional confirmation is sometimes required. After 7 clicks on Build number you may be asked to enter your PIN code or account password Samsung. If you forgot your password, recover it through the website account.samsung.com.

Security: dos and don'ts in Developer Options

Developer mode gives you great power, but with great power comes great responsibility. Careless actions can:

• 🛡️ Reduce data protection —for example, enabling USB debugging allows the connected PC to access files.
• 🔋 Increase battery consumption —if you disable background optimization processes.
• 📉 Worse performance - incorrect settings GPU or CPU can cause lags.

To avoid problems, follow these rules:

• ✅ Enable USB debugging only if necessary (for example, for flashing or working with ADB). After use, disable it.
• ✅ Do not change settings related to OEM Unlockif you do not plan to unlock the bootloader.
• ✅ Before experiment, create a backup copy via Settings → System → Backup.
• ✅ Do not turn on Do not turn off the screen on an ongoing basis - this shortens the life of the display.

If you accidentally changed a critical setting and your smartphone starts to become unstable, try resetting the developer options to default values. To do this:

1. Open Settings → System → For Developers.
2. Click on the three dots in the upper right corner (menu).
3. Select Reset settings.

💡

Developer options are a powerful tool, but most changes do not require root access. Be careful with settings related to security (OEM Unlock) and performance (GPU acceleration).
