Xiaomi smartphone owners often face a situation where the interface suddenly becomes unreadable due to too large elements. This can happen by accident if the zoom function is activated in the pocket or bag, or after updating the MIUI and HyperOS firmware, the display settings may be confused. The image becomes so large that you can not press the back button or get into the desired menu, turning the use of the device into torture.
The problem is solved quickly enough if you know where to look for switches. In Android, which is the shell of a Chinese manufacturer, there are several different parameters for this. You need to distinguish between a simple enlargement of the font, a magnification mode for the visually impaired and a global size of interface elements. In this article, we will discuss in detail all possible causes and ways to eliminate them.
Don't panic if your screen is gone. It's a software setup, not a matrix or a touchscreen breakdown. A good calibration will bring back the comfort of your gadget in a few minutes. Next, we'll look at step-by-step algorithms to get back to the standard values.
Disabling the magnification mode for the visually impaired
The most common reason for this dramatic zoom change is the accidental activation of a special accessibility feature that is designed for people with poor vision, and allows you to triple-press the contents of the screen or create a floating window of a magnifier, and if you have a magnifier on your screen or an image twitches when you touch, then this mode is active.
To remove this effect, you need to get into the system settings. Since the screen can be greatly enlarged, use gestures to move around the desktop to find the settings icon. You need to go to Settings → Additional settings → Special features. In some versions of the firmware, the path may look like Settings → Advanced settings → Special.
In the menu that opens, look for "Increase" or "Magnification." Inside this section, there will be a switch that you need to put inactive, and it's also worth checking the settings "One-touch Increases" or "Three-touch" to prevent accidental activation in the future.
⚠️ Warning: Don't confuse this mode with the usual zoom in a gallery or browser. If the image is only enlarged in specific applications when dividing your fingers, it's a regular feature, not a system failure.
Why is the magnifying glass activated?
Once the function is turned off, the screen should immediately return to its normal size. If this does not happen, try restarting the device by pressing and holding the power button. In rare cases, it is necessary to re-energize and turn off the display to apply the changes.
Setting the font size and interface elements
If the visually impaired mode is disabled, but the text and icons still look unnaturally large, the problem lies in the display settings. MIUI allows you to flexibly adjust the font size regardless of the size of the interface elements themselves. Often users change these settings in an effort to improve readability, and then forget how to return everything back.
To correct, you need to follow the Settings → Screen → Text Size path. Here you will see a slider. Move it to the center position or select the default value. Note that there may be a separate switch for Large Font in the same menu, which you must deactivate.
Separately, it is worth checking the size of the elements. This parameter affects buttons, indentations and widgets. It is usually located next to the font settings or in the section Additional → Element Size. The optimal value is an average, which provides a balance between information content and convenience.
Changes are instant. You can experiment with sliders by watching the previews on the screen until you find a comfortable option. You don't recommend setting minimum values, as this can make the text unreadable to others.
Resetting special features settings
Sometimes manually disabling features doesn’t help because of software conflicts or errors in the Google Play Services, and in such cases it’s more effective to reset the special settings completely, returning all availability settings to factory values without affecting your personal data, photos or contacts.
To do this, go to Settings → Applications → All apps. In the list, find "Special Opportunities" or "Accessibility." Click on the three dots in the upper right corner (or "More") and select "Reset Settings." The system will request confirmation of action.
Once confirmed, all services such as TalkBack, Voice Access and zoom in will be disabled, a guaranteed way to remove any imposed interface changes related to access.
☑️ Post-dump check
It's important to understand that after resetting, you'll have to reconfigure the features you want if you're actually using them, but this is one of the most effective ways to address the problem of sudden screen enlargement.
One-Hand Mode and Its Impact on Scale
On the big screens of Xiaomi Redmi and Poco smartphones, "One Hand Mode" is often active, and when it is turned on, the contents of the screen are compressed and shifted into a corner, which can visually be perceived as a zoom change, although technically it is a decrease, not an increase. However, the incorrect operation of this mode can cause display artifacts.
You can check the status of this feature in the Settings menu → Additional settings → One-hand mode. If the slider is active, try turning it off. Also pay attention to the activation method: it is often turned on by swipe down the bottom navigation bar or the Home button.
It happens very often, and you may not notice that you've hit the bottom of the screen and the interface is compressed. You usually exit by tapping a special arrow or swiping again, but the easiest way to turn it off is to turn it off completely in the settings if you're not using it.
⚠️ Warning: One-hand mode is not an increase, but it creates similar navigation problems.Make sure you don't confuse interface compression with font enlargement.
If you prefer to use your smartphone with one hand, set up activation on schedule or only at a certain position of the proximity sensor to avoid accidental switching on.
Problems with screen resolution and DPI
More advanced users may have experienced a change in DPI (dot per inch) or screen resolution, often after custom themes are installed, system modifications or an engineering menu, and the change in pixel density drastically changes the size of all objects on the screen.
Return the standard value DPI You can use the developer menu. → The phone. → Press "Versions" MIUI" 7 times → Additional settings → For developers, look for the "Smallest width" option).
The default value varies depending on the model. For most modern Xiaomi smartphones, this number is in the range of 360 to 411 dpi. If you see a value of 100 or 800 there, it is clearly not the norm.
| Smartphone model | Standard permission | Recommended DPI | Pixel density |
|---|---|---|---|
| Xiaomi Redmi Note 10 | 2400 x 1080 | 392 dpi | ~441 ppi |
| Xiaomi Mi 11 | 3200 x 1440 | 392 dpi | ~515 ppi |
| Poco X3 Pro | 2400 x 1080 | 392 dpi | ~395 ppi |
| Xiaomi 13 | 2400 x 1080 | 392 dpi | ~395 ppi |
Type the correct value for your model and click "Apply." The screen may blink and the interface will return to its normal proportions. Be careful: setting a DPI too high can make text microscopic, and too low can break the layout of some applications.
💡
Write down your model's standard DPI value on paper or in the cloud before you experiment, which will save you if the settings go wrong again.
Use of Engineering Menu and ADB (for Advanced)
If standard methods don't work, you can use deeper customization tools, the MIUI Engineering Menu allows you to test the display, but also contains hidden settings, and you can log in via the Phone app by typing code ##6484##.
But the most powerful tool is ADB (Android Debug Bridge) debugging, which is that if you plug your phone into your computer, you can reset any scaling settings with your command, and that requires a PC and drivers installed.
The command to reset the density of the screen looks like this:
adb shell wm density resetPerforming this command instantly returns the pixel density to the factory one, and you can also reset the display size:
adb shell wm size reset⚠️ Attention: Use ADB The wrong commands can cause the interface to become unreadable, and only a complete reset can restore access).
This method is recommended only for those users who understand what they are doing, and for most cases, the settings inside the phone are enough.
💡
Using ADB is "heavy artillery," and only use it if the software settings on the phone's menu are locked or not working.
