In the era of digital communications, the need to quickly share information from a smartphone screen arises constantly. Whether it’s a screenshot of correspondence, instructions or an interesting article, users are looking for ways to capture exactly the desired fragment, and not the entire screen. The standard function of capturing the entire image often requires subsequent cropping, which is inconvenient and takes up unnecessary time.
Fortunately, modern versions of the operating system Android and add-ons from manufacturers offer built-in tools for capturing an arbitrary area. This allows you to instantly highlight and save only the part of the content that matters. In this article, we will analyze in detail all the available methods, from system gestures to the use of third-party utilities, so that you can choose the most suitable option for your device.
It is worth noting that the set of tools may vary significantly depending on the model of your gadget and the firmware version. Some brands, such as Samsung or Xiaomi, implement their own unique image processing algorithms. Therefore, it is important to take into account the features of your specific smartphone when searching for the desired function in the settings menu.
Standard capabilities of the Android operating system
Starting with certain versions, pure Android and many custom skins received native support for cropping screenshots immediately after taking a picture. This process is intuitive and does not require the installation of additional software. After you have taken a regular screenshot, a thumbnail of the image appears at the bottom of the screen.
Clicking on this thumbnail takes you to the editor, where there is often a “Crop” button or a special icon in the form of a frame. By activating it, you can move the selection borders, leaving only required area. This is a basic method that works on most devices running Android 10 and newer without any additional settings.
However, if the standard editor does not have a random selection function, the system may offer the “Long Screenshot” mode or scrolling. While it's not exactly the same as taking a partial screenshot, this tool is useful for capturing long lists or conversations. In some cases, the system itself analyzes the content and offers to select text or a table.
It is important to understand that the operating algorithms of standard tools depend on the manufacturer. On some devices, the cropping feature is only available after the file is saved to the gallery, and not when the photo is taken. Check the Screen settings in your menu to make sure there is a quick editing option.
If the standard editor does not allow you to select the desired area the first time, try zooming in on the image before cropping for greater accuracy.
Using Google Assistant for smart capture
Google's voice assistant has a wide range of functionality, including the ability to create screenshots via voice commands or interface. This is especially convenient when your hands are full or when you need to quickly capture information without using physical buttons. The function is called “Screen capture” and is integrated directly into the assistant.
To use this method, just activate Google Assistant with the phrase “Ok Google” or by long pressing the “Home” button. After this, say the command “Take screenshot” or select the corresponding icon in the menu that appears. The assistant will create a photo and immediately offer options for action, including editing and highlighting an area.
The advantage of this method is its versatility. It works on almost all smartphones with Google service installed, regardless of the device brand. In addition, the assistant can recognize the text in the image and offer to copy it, which adds functionality to a simple screenshot.
To activate the function, make sure that screen access is allowed in the assistant settings. Sometimes you need to additionally enable an option in the Settings → Applications → Google → Settings → Google Assistantsection. If the item is missing, your version of the software may not have received this update yet.
Branded solutions from smartphone manufacturers
Large vendors often expand basic functionality Android, adding unique gestures and menus for working with the screen. For example, devices Samsung with a shell One UI allow you to draw with your finger on the screen to take a picture, and then immediately proceed to editing. This significantly speeds up the process of saving the desired fragment.
Smartphones Xiaomi i Redmi offer a convenient way to capture an area through the notification menu. After taking a regular screenshot, the “Crop” button appears, which launches a special selection mode. The user can select a rectangular area, save it, or immediately share it in the messenger. The “Long Screenshot” function is also available for scrolling pages.
Devices from Huawei i Honor use the “knuckle” gesture. By tapping your knuckle on the screen and drawing a line, you can select an arbitrary area of any shape. This is one of the most elegant methods, allowing you to trace objects of complex geometry, not just rectangles. The system automatically detects borders and creates a clean photo.
⚠️ Warning: Control gestures may conflict with actions inside some applications, especially games. If the function does not work, try changing the touch sensitivity in the system settings.
Below is a table comparing area capture methods from popular manufacturers:
| Brand | Activation method | Editing features | Accessibility |
|---|---|---|---|
| Samsung | Edge panel / Gesture | Smart object selection | One UI 2.0+ |
| Xiaomi | Screenshot menu | Quick cropping and sharing | MIUI 11+ |
| Huawei | Knuckle finger | Free-form selection | EMUI 9.0+ |
| Google Pixel | Google Assistant | Integration with search | Android 10+ |
Proprietary gestures often work faster than standard buttons, but require habituation and precision of movements.
Third-party applications for advanced screenshots
If the built-in tools of your smartphone do not meet your needs, specialized applications from Google Playcome to the rescue. They offer advanced functionality: scheduling screenshots, capturing scrolling pages, watermarking, and sophisticated editing tools. One of the popular solutions is the application Screen Master.
Such utilities often have a “Floating Button” mode, which is always on top of other windows. By clicking on it, you can instantly select the area to capture. This is especially useful when working with maps or documents where you need to frequently capture different areas of the screen. Some applications also support text recognition (OCR) directly on the image.
When choosing third-party software, pay attention to the requested permissions. For the screen capture feature to work, the application must have the right to display on top of other windows and access storage. Avoid suspicious apps with a lot of advertising, as they can slow down your device.
Many advanced tools allow you to create collages of several screenshots or add arrows and comments before saving the file. This turns your smartphone into a powerful tool for creating instructions and presentations. However, it is worth remembering that the constant running of such applications in the background can increase battery consumption.
Why do some applications prevent you from taking a screenshot?
Banking applications and services with confidential data block the ability to take screenshots at the Android security level. This is protection against information leakage, and it is impossible to bypass it using standard means.
Configuring and optimizing the saving process
To make the process of creating screenshots of part of the screen as efficient as possible, it is recommended to correctly configure the saving folder and file format. Most smartphones by default save screenshots to a folder Screenshots in the internal storage. You can change this path in the gallery or file manager settings to organize your files.
The choice of file format also plays a role. Standard JPEG provides good compression, but may lose quality with repeated editing. The format PNG saves the image without loss, which is critical for screenshots with text or graphics, but takes up more space. Check your camera or screenshot app settings to see which option is best for you.
Regularly cleaning out your screenshots folder will help free up space on your device. Screenshot files often accumulate and take up gigabytes of memory. Use built-in cleanup tools or third-party file managers to remove outdated images that are no longer needed.
You can use macros or scripts for automation if your shell supports it. For example, you can configure the action so that when you take a screenshot, the editor or the Share menu immediately opens. This reduces the number of touches and speeds up the workflow.
☑️ Optimizing work with screenshots
Solving problems and limitations
Despite the abundance of methods, users may encounter situations where they cannot take a screenshot of part of the screen. Most often this is due to application security policies. Banking clients, instant messengers with secret chats and streaming services block the screenshot function at the system level to prevent data leakage or copyright infringement.
In such cases, the screen may turn black when attempting to capture, or the system will issue a notification about the prohibition. It is impossible to bypass this limitation by legal means without obtaining root access, which is not recommended for ordinary users due to the risk of loss of warranty and system instability. The only way out is to take a photo of the screen with another device.
Another problem may be incorrect operation of the sensor or gestures. If you use the knuckle or swipe method, make sure there is no protective film on the screen that will interfere with accurate touch recognition. Also check if the “Work with gloves” mode is enabled, which can change the sensitivity of the display.
⚠️ Attention: Interfaces and menu names may change after updating the firmware. If you do not find the described function, use the search in your phone settings by entering the keyword “screenshot” or “screen.”
Sometimes the problem lies in the lack of RAM. If the device is heavily loaded, image creation and processing may be interrupted. Close background applications before performing complex operations with screenshots, especially if you use heavy editors.
To bypass screenshot blocking, in some cases, turning off the Internet before entering the application helps, but this does not always work and depends on the specific software version.
Is it possible to take a screenshot of part of the screen on an old Android?
On Android versions below 9.0 there is usually no built-in function for cropping an area. You will have to take a full screenshot and then crop it in any photo editor or gallery. You can also install a third-party application that emulates this function.
Why is the screenshot blurry?
Blur can occur when using digital zoom before taking a photo or when saving in JPEG format with a high level of compression. For clarity, use the PNG format and take a photo at the native screen resolution without prior scaling.
How to take a screenshot in incognito mode?
Browsers in incognito mode often block taking screenshots for privacy reasons. In this case, standard methods will not work. The only option is to take a photo of the screen on another device or use the screen recording function if it is not blocked.
Where are screenshots of part of the screen stored?
By default, all snapshots, including cropped areas, are saved in the same folder as regular screenshots. Usually this is a directory DCIM/Screenshots or Pictures/Screenshots in the internal storage. The file name may contain a note about editing.
Does taking screenshots affect the battery?
The image capture process itself consumes a minimal amount of energy. However, using third-party applications with constant screen tracking or video recording functions can significantly speed up battery drain.
