Xiaomi Redmi Note 7, powered by MIUI, hides a powerful tool from users: the developer mode. This hidden section of settings allows you to fine-tune performance, debug applications, and even overclock hardware. But how do you activate it when the manufacturer has hidden access?
Unlike standard settings, developer settings are not displayed in the default menu, but must be unlocked through a special sequence of actions known only to advanced users. In this article, we will go through all the steps from preparing the device to checking for successful activation, and also explain what functions become available after the mode is turned on.
Why the developer’s options are hidden on the Redmi Note 7
Xiaomi and the MIUI team are deliberately hiding these settings from ordinary users, for several reasons:
- 🔧 Danger of incorrect settings – changing parameters without understanding can lead to system failures or overheating of the processor
- 🛡️ Protection from accidental actions – many options directly affect the safety and stability of the work
- 📱 Android compliance – Google recommends hiding these settings for mass users
But for enthusiasts and developers, this mode offers unique opportunities, from debugging through ADB to changing the animation interface. On the Redmi Note 7 with its Snapdragon 660 and 3/4 GB of RAM processor, these settings are especially relevant for optimizing performance.
Preparation of the smartphone before switching on the mode
Before activating the developer’s parameters, follow the mandatory preparatory steps:
- Check the MIUI version in Settings → About Phone → MIUI version
- Make sure your battery is over 30%, which will prevent a sudden shutdown.
- Backup important data through Settings → Additional → Backup
On the Redmi Note 7 with MIUI 12.5 and later, the activation algorithm may be different from the older versions. If your smartphone runs Android 9 Pie (which is typical of this model), the procedure will be standard.

Where to find the developer's settings after activation
After successful unlocking, the new section will appear mainly in the settings menu, but its location depends on the version of MIUI:

|---|---|---|
| MIUI 10-11 | Settings → Advanced settings → For developers | You may need to include a slider at the top of the screen. |

- 🔄 Background processes – limiting the number of running applications to save battery
- 📡 Debugging by USB — necessary for the operation of ADB custom-made
- 🔒 Unlocking OEM — mandatory step before unlocking the loader
