Hidden Developer options in Android 11 open access to dozens of additional settings that manufacturers usually hide from the average user. This mode is initially intended for testing applications, debugging the system and fine-tuning performance, but even ordinary smartphone owners can benefit from it. For example, here you can speed up interface animation, enable USB debugging to work with ADB, or force activation GPU acceleration for individual applications.

Unlike newer versions Android (starting from 12th), where Google has tightened control over some options, Android 11 keeps most of the “developer features” in their original form. However, the process for activating this menu is not obvious: it cannot be found in the standard list of settings. In this article we will look not only how to enable developer optionsbut also which settings should be changed first and which ones are not recommended to be touched. We will pay special attention to the nuances for devices from Samsung, Xiaomi and other manufacturers, where the interface may differ.

Why developer options are hidden by default

Google and smartphone manufacturers deliberately hide this menu, and for good reason. Firstly, most of the options here are intended for professional developers and can lead to system instability if changed at random. For example, forcibly enabling 4x MSAA (anti-aliasing in games) on weak devices will cause lags, and disabling restrictions on background processes will drain the battery in a few hours.

Secondly, some settings directly influence security. Thus, activation USB debugging allows the connected computer to gain expanded access to smartphone data - this can be dangerous if the device falls into the wrong hands. For the same reason, Android 11 there is an additional confirmation when this option is enabled.

  • 🔧 Risk of instability: Changing kernel or GPU parameters may lead to overheating or sudden reboots.
  • 🔒 Security threats: USB debugging and unlocking OEM Unlock open access to system partitions.
  • ⚡ Impact on autonomy: Options like Do not turn off the screen or Background activity quickly drains the battery.

However, proper use of the developer mode allows increase interface performance by 15-20% by disabling animationsto improve display quality in games or even restore the device’s functionality after a failure. The main thing is to know which settings are responsible for what.

Step-by-step guide: how to enable developer mode

The activation process is the same for most devices on Android 11, but may vary slightly depending on shells (for example, One UI y Samsung or MIUI y Xiaomi). We will look at the universal method, and then point out the features for popular brands.

  1. Open Settings your smartphone.

  2. Go to the About phone section (sometimes called About device or Information about phone).

  3. Find item Build number (or MIUI version for Xiaomi, Software build number for Samsung).

  4. Click on this item 7 times in a rowAfter the first three clicks, a notification will appear indicating that you are close to unlocking the mode. developer.

  5. On the 7th press, the system will display a message You have become a developer! or similar.

Now in the main menu Settings a new section will appear - Developer options (may be in the submenu System or Advanced). On some devices (for example, Huawei) this item is called For developers.

Click on "Build number" 7 times|

The notification "You have become a developer!" has appeared|

A new section "Developer Options" has appeared in the "Settings" menu|

Reboot the device (optional)-->

⚠️ Attention: On devices with MIUI 12+ (for example, Xiaomi Redmi Note 10) after activating the developer mode, additional confirmation may be required in the section Accessibility → Settings developer. Without this, some options will not be available.

Where to find developer options after activation

After successful activation, the new section may be “hidden” in different places depending on the firmware. Here is where to look for it on popular devices:

Manufacturer Shell Path to developer options
Google Stock Android Settings → System → Developer options
Samsung One UI 3.x Settings → Advanced → Developer options
Xiaomi MIUI 12/13 Settings → About phone → Advanced → Developer options (or via search)
Huawei/Honor EMUI 11 Settings → System and updates → Developer options
Realme/Oppo ColorOS 11 Settings → Additional settings → Developer options

If the section is not displayed even after 7 clicks on Build number, try:

  • 🔍 Use search by settings (enter "developer").
  • 🔄 Reboot the device - sometimes the menu appears only after a reboot.
  • 📱 Check if the section in the submenu is hidden (for example, System → Additionally).
⚠️ Attention: On some devices Samsung after updating to One UI after updating to Android 11 developer settings may be reset. In this case, you will have to click on Build number.

Top 5 useful settings in developer options

From hundreds of available options, we have selected those that will bring real benefits to the average user without risk to the system Remember: do not change parameters whose purpose you do not understand.

1. Speed ​​up the interface (disable animations)

Default Android uses smooth animations when opening applications, minimizing windows and switching between screens. Disabling them will make the interface visually faster (although actual performance will not change).

  • Window animation scale → No animation or Animation 0.5x
  • Transition animation scale → No animation
  • Duration animator → Disable

2. Enable USB debugging (for ADB)

This option is necessary for working with a computer via Android Debug Bridge (ADB. With its help you can:

  • Install applications in bypass Play Market.
  • Back up system data.
  • Unlock bootloader (if supported).

To enable:

  1. Activate USB debugging.
  2. Connect your smartphone to your PC and confirm your trust in the computer.
💡

If USB debugging does not turn on, check whether your antivirus or corporate policy is blocking it (on work phones).

3. Force GPU acceleration to be enabled

This option forces the system to use the GPU to render the interface, which can speed up work on weaker devices. However, on some smartphones this leads to overheating or artifacts.

  • Forced use of GPU → Enable (experimentally).
  • Display hardware overlays → Enable (for testing performance).

4. Allowing OEM unlocking

If you plan to install custom firmware or receive root access, this option must be activated before starting manipulations. On some devices (for example Samsung) it is automatically disabled after a reboot.

  • OEM unlocking → Enable.

5. Error log and process log

Useful for diagnosing problems. Here you can:

  • Enable Process log (shows active applications).
  • Activate Strict mode (highlights slow operations).
💡

Changing parameters Dalvik VM or Background process limit can lead to system crash. You should not touch them unless absolutely necessary.

What NOT to do in the developer options

Some settings may disable the device forever or make it vulnerable to attacks. Here is a list of the most dangerous options:

  • 🚫 Change Kernel settings - this can lead to a “brick” (inability to turn on the phone).
  • 🚫 Disable Data protection - makes the device vulnerable to malware.
  • 🚫 Change Settings Wi-Fi manually —risk of losing the network.
  • 🚫 Activate Fake locations unnecessarily - it disrupts the operation of geoservices.

Also not recommended:

  • Enable Do not turn off the screen —this will quickly drain the battery.
  • Change Bluetooth settings manually—may break pairing with devices.
  • Disable Optimizing MIUI (on Xiaomi) - will lead to lags.
What will happen if you reset the developer options?

When Resetting all settings (Resetting settings in the developer menu) will return to default values, but the section itself will remain accessible. To completely remove it, you need to manually delete the file /data/property/persist.sys.dev_opts (root required).
