Xiaomi’s modern smartphones are famous for their huge displays that provide incredible immersion in content, but often create problems when controlling one hand. Owners of models with a diagonal of more than 6.5 inches know that it is almost impossible to reach the top corner of the screen with your thumb without intercepting the device.
This feature allows you to instantly reduce the active area of the display, shifting all the controls to the bottom of the screen, making them accessible to the thumb. enabling this option does not require complex manipulations or superuser rights, however, the location of the settings can vary depending on the version of the MIUI shell or the new HyperOS.
In this article, we will analyze in detail the activation algorithms for different versions of firmware, consider the features of the gesture and answer frequently asked questions. You will learn not only to turn on the mode, but also to customize it to your habits, making the use of a large-format gadget as comfortable as possible in any situation.
What is the mode of one hand on Xiaomi smartphones
One-Hand Mode is a software feature of the Android operating system, adapted by Xiaomi developers for MIUI and HyperOS shells. Its main task is to scale the interface: the screen visually shrinks, occupying about two-thirds or half of the display area, and moves to one of the lower corners, which allows the user to reach all the elements of the interface without letting the device body out of the palm.
It's important to understand that this is not just zoom, but a complete change in the input and display area of content. System fonts, application icons and navigation buttons retain their proportions, but become more compact relative to the physical dimensions of the matrix, which is critical for people with small hands or for situations where the second hand is occupied, for example, in public transport.
The feature is integrated deep into the system layer, which ensures its stable operation in almost all applications, including instant messengers, browsers and system menus. However, it is worth noting that in some games or video players running on the full screen in landscape mode, activation of the mode may be limited or impossible due to the orientation of the interface.
History of the emergence of the function
Activation of the function in modern versions of MIUI and HyperOS
In current firmware versions like MIUI 14 and the latest HyperOS, the path to customization has become more logical, although it requires care. The settings interface has been redesigned for unification, so menus may look different than in older versions.
Find the section that provides additional system settings. Depending on the regional version of the firmware (Global, Chinese, Russian), the name of the item may vary slightly, but the logic remains the same. You will need to find a category associated with additional features or special features.
☑️ Algorithm for initiation of the regime
Once the main switch is activated, the system will suggest you choose the call method. The most popular and convenient is the use of a special gesture that does not require touching the screen buttons. You can also use a floating button, but it takes up space on the screen and can overlap the content in some applications.
⚠️ Note: In some models with a camera cutout or dynamic islet, the gesture activation area may be shifted to avoid conflict with system elements. If the gesture does not work the first time, try swiping your finger just below or above the standard zone.
Customize gesture and size of the reduced screen
One of the key features of this feature in Xiaomi smartphones is the ability to fine-tune it. Once you turn the mode on, you have a slider that adjusts the size of the reduced window, you can make the screen very small for maximum convenience, or you can leave it large enough to read text comfortably.
In addition to the size, the window position is also customized; by default, it shifts to the bottom right corner, which is convenient for right-handers; left-handers can change their position to the opposite side to control the smartphone with their left hand without crossing their fingers; switching between sides is instantaneous.
The gesture mode calling mechanics requires a certain skill, and you need to swipe from the bottom of the screen (from the navigation buttons or the bottom edge when you're controlling gestures) diagonally to the center, and the movement should be smooth but confident.
💡
To quickly change the side of the screen in active mode of one hand, you do not need to climb into the settings. Just swipe your finger from the side of the reduced window in the opposite direction, and the interface instantly moves.
There is also the possibility of completely deactivating the gesture if you accidentally call this mode too often, in which case it is better to leave only the program button or turn off the function altogether, since constant false positives can be annoying when typing actively.
Using a floating button to control
If gestures seem uncomfortable to you or often don’t work because of the protective glass with curved edges, a great solution is to use a floating button. This interface element is a small round icon that can be dragged around the screen.
When you activate this option, you have a button on the screen that shows you a hand or a smartphone, and you tap it instantly turns the interface into one hand, and you press it again, and you get the screen back to its original size, and you don't have to remember complex finger movements.
The floating button has its advantages, especially for people with limited motor skills or those who prefer tactile response over swipes, but there is a downside to this method: the button can overlap important elements in games or when watching videos, if not pushed back into the corner.
Specifics of work on different models of Redmi and POCO
While the software is uniform across devices, hardware features can make adjustments, such as on low-end Redmi models with less-performing processors, screen-curling animations can take a fraction of a second longer than on the flagships of the Mi or Xiaomi 13/14 series.
Gamer-oriented POCO devices sometimes have a modified interface logic in Game Turbo mode. In some cases, when a game is launched, one-hand mode can be blocked by the system to prevent accidental taps and it will have to be activated manually through the toolbar.
On very high-resolution (2K or 4K) models, zooming out can make the text too small to read comfortably without squinting, and in such cases, it is recommended to increase the font size in the main system settings in parallel using one-handed mode.
| Series of devices | Features of activation | Recommended window size |
|---|---|---|
| Xiaomi (Flagships) | Instant response, support for all gestures | 60-70% of the screen |
| Redmi Note | Standard implementation of MIUI | 50-60% of the screen |
| POCO (X/F series) | Possible conflicts in Game Turbo | 65-75% of the screen |
| Budgetary models (C/A) | Slow-motion animation of the interface | 50% screen |
Problem Solving and Troubleshooting
Despite the system's fine-tuning, users may encounter situations where the mode is not turning on or is not behaving correctly, most often the problem lies in a conflict with third-party launchers. If you are using an alternative desktop from Play Market, the system gesture may simply not be processed.
Another common reason is the enabled Sensitivity feature in screen settings, which sometimes interprets swipe for one-handed mode as a normal touch or scrolling, in which case it is worth trying to calibrate the sensor or temporarily disable the sensitivity boost.
If the mode is turned on but the screen remains black or distorted, this may indicate a temporary failure of the graphics driver.Rebooting the device 90% of the time solves this problem. Also make sure that the phone has the latest available security update.
⚠️ Warning: Do not attempt to activate one-handed mode during the system update or data recovery process. At these times, the interface may be blocked, and an attempt to zoom will cause the touchscreen to freeze until the reboot.
💡
If standard methods don’t work, check to see if you have modified interface scaling (DPI) developer mode enabled, as this may conflict with one-handed system mode.
