The Xiaomi Redmi 7 is still a popular choice for years, thanks to its balanced features and flexible MIUI firmware. However, many users do not realize that a powerful tool is hidden under the hood of the system - the developer mode. This hidden section opens up dozens of additional settings from animation acceleration to debugging over USB, which is especially valuable for enthusiasts of customization and software testing.
Turning on the developer mode on Redmi 7 takes less than a minute, but requires a precise follow-up. It is important to understand that activating this mode does not invalidate the warranty (unlike unlocking the bootloader), but allows you to fine-tune the system to your needs. In this article, we will discuss not only the standard way to turn on, but also alternative methods for cases where the About menu behaves incorrectly, and you will learn which settings should be changed first and which should not be touched without experience.
Why you need a developer mode on Xiaomi Redmi 7
Developer Options (or Developer Options) is originally designed to test and debug applications, but its features are useful for ordinary users, as well.
- 🔧 Speed up the interface: reducing window animation and transition time (window animation scale settings).
- 📱 Emulation of other screen resolutions: useful for adapting the interface to the tablet mode.
- 🔌 Debugging by USB: mandatory point of operation ADB, Firmware through Fastboot or using tools like Scrcpy.
- 📡 Advanced network settings: forced VoLTE enabled, network type choice (2G/3G/4G) or displaying the signal level in dBm.
- 🔄 Background Processes: Limiting the number of running applications to save battery.
On Redmi 7 with MIUI 10–14 firmware, the developer mode also allows you to bypass some system limitations, such as turning off automatic memory optimization, which sometimes closes the desired applications, or turning on an error log to diagnose problems. However, it is important to remember that not all settings are safe. Changing settings associated with OEM Unlock or MI Unlock can lead to a data reset or lock the bootloader.

Alternative Incorporation Methods (if Standard Incorporated Does Not Work)
In rare cases, the standard method may fail due to system failures or customized firmware, and here are two proven workarounds:
Method 1: Through ADB (for power users)
If you have access to your computer and have ADB drivers installed, do:
adb shell settings put global development_settings_enabled 1
adb shell am broadcast -a com.android.settings.APPLICATION_DEVELOPMENT_SETTINGSAfter that, the developer mode will appear in the settings, and this method works even if the About Phone menu is not available.
Method 2: Resetting the pressure counter
Sometimes the press counter gets knocked down to drop it.

Security: What not to do in Developer Mode
Developer mode allows low-level access to the system, so some actions can harm the device.
- 🚫 Enabling Unlocking OEM Unnecessarily: This weakens the bootloader’s protection and may result in the device being locked the next update.
- 🚫 Background check settings change: Disabling background check makes phone vulnerable to malware.
- 🚫 Demo Mode Activation: This mode hides notifications and real charge levels, which can be misleading.
- 🚫 Manually configure Mobile data always active: Forced activation of mobile data in the background quickly drains the battery.
Particular care should be taken with settings related to firmware and bootloader. For example, enabling Advanced Reboot adds Recovery and Fastboot items to the off menu, which is convenient for advanced users, but can lead to an accidental data reset.
💡
Developer mode does not void the warranty on its own, but careless changes (such as unlocking the bootloader) can lead to its loss. Always back up before experimenting.
