Modern Android smartphones have powerful image processing tools, which are often hidden behind a simple interface. Users are often faced with the need to highlight a specific detail in a photo in order to focus the interlocutor’s attention on it or to save important information for later analysis. This can be done in several ways, from standard screenshot functions to special editing applications.
Depending on the version of the operating system and the installed shell, the methods may vary significantly. Owners of Samsung, Xiaomi or Google Pixel devices have access to different sets of tools, but the basic principle remains the same.

We'll also touch on the advanced selection techniques available in the latest Android updates.
Using the built-in editor after taking a screenshot
The fastest way to select an object on the screen is to use the instant editing panel that appears immediately after taking a screenshot. In most modern firmware, such as MIUI, One UI or pure Android, when you press the combination of the volume and power buttons, a thumbnail appears at the bottom of the screen.
By clicking on this thumbnail, you are taken to the quick edit mode. A selection of drawing tools are usually available here, including a marker, a pen, and a selection tool. You can choose a bright color and simply trace the desired element with your finger. The system will automatically smooth the lines, making the stroke neat.
Please note that the lifetime of this panel is limited. If you close the notification or switch to another app, the thumbnail will disappear and you'll have to look for the photo in your gallery. For operational work, this method is the most effective solution.
⚠️ Attention: On some models of budget smartphones, the quick editing panel may be missing or work with a delay. In this case, the image is immediately saved to memory, and you will have to edit it through the Gallery application.
It is also important to take into account the resolution of your screen. When taking high-resolution screenshots, fine details may be lost during compression if you plan to send the file via instant messengers without losing quality. Use the settings Image compression in the system settings, if such an option is available.
To quickly open the screenshot editing panel, try swiping up from the bottom corner of the screen immediately after taking a photo (the gesture may differ depending on the model).
Editing photos through the standard Gallery
If you need to circle an element on an existing photo taken with a camera or downloaded from the Internet, you should turn to the standard Gallery application. Almost every manufacturer preinstalls its own editor, which contains a section Markup or Drawing.
The process usually looks like this: you open the image, click the edit button (often a pencil icon) and select the brush tool. In the advanced brush settings, you can change the line thickness, transparency and even the type of tip, which allows you to create more expressive accents.
Device from Samsung deserve special attention. Their proprietary editor has a function for automatically selecting objects. You can click on an item in the photo, and the system itself will outline it, creating a sticker or cut-out element. This greatly simplifies working with complex shapes.
- 🎨 Select the Marker tool to create a semi-transparent highlight of an important area.
- ✏️ Use the Fine Pen to accurately trace small details of text or numbers.
- 🔲 The Shapes tool will help you select an object a neat rectangle or circle.
After finishing editing, do not forget to save a copy of the file. Many editors will overwrite the original by default, which can be inconvenient if you need the original image in the future. Look for the option Save as a copy in the export menu.

Advanced tools in Google Photos and new versions of Android
The Google ecosystem offers some of the most intelligent processing tools. In the application Google Photos, which is installed on most certified devices, the markup function is integrated very deeply. It is available not only for screenshots, but also for any images in your library.
Starting with Android 12 and higher, the system offers contextual hints when editing. If you choose a drawing tool, algorithms may suggest straightening your line or turning your sketched circle into a perfect geometric shape. This is called the Drawing Assistant feature drawing assistant.
In addition, recent updates have introduced the ability to use stylized markers. You can choose not just a solid line, but dashed, dotted or even a line with a glow effect. This is especially useful when creating instructions or training materials directly on your phone.
| Function | Where to find | Feature |
|---|---|---|
| Markup | Edit button -> "Markup" | Basic set of brushes |
| Magic eraser | Tools -> Magic eraser | Removing unnecessary objects |
| Focus | Tools -> Blur | Selecting an object by blurring the background |
It is worth noting that some advanced functions of Google Photos may require a Google One subscription or the presence of specific hardware for neural networks to work on the device. If the option is not available, check your cloud sync settings.
Why aren't all features available for free?
Some AI-powered tools require significant processing power from Google servers, so the company limits access to them for premium subscribers.
Third-party apps for professional annotation
When the built-in tools are not enough, specialized applications from the Google Play Store come to the rescue. There are many solutions focused specifically on creating screenshots with notes and professional annotation of images.
The leader in this niche has long been the application Markdroid or Annotate. They provide an expanded set of tools: arrows with automatic alignment, numbered lists directly on the photo, text blocks with different fonts and the ability to add blur (blur) to hide confidential information.
Another popular option is to use general-purpose graphic editors such as PicsArt or Snapseed. Although they are focused on artistic processing, the drawing tools in them are implemented at a very high level, allowing you to create complex compositions.
- 📐 Built-in rulers and grids for ideal positioning of elements.
- 🔒 "Pixelization" function to hide passwords and personal data before sending.
- 💾 Automatic saving to a specified folder without cluttering the main gallery.
When choosing an application, pay attention to the permissions it requests. To work with photos, access to the multimedia storage is sufficient. If a app requires access to your contacts or microphone for no obvious reason, it is better to refrain from installing it.
⚠️ Attention: Free versions of popular editors often contain intrusive advertising that may block the work area. Consider purchasing the Pro version or using open source analogues.
Features of working on devices from different manufacturers
The fragmentation of Android means that the interface and editing capabilities are highly dependent on the brand of your smartphone. Understanding these differences will help you quickly find the desired button in the menu.
Xiaomi and Redmi devices use the MIUI (or HyperOS) shell, where the editor is built right into the screenshot preview. There is a separate tab with markers, stickers, and even the ability to recognize text for subsequent copying.
Samsung smartphones with the One UI shell offer perhaps the richest functionality. Here you can not only draw, but also cut out objects, change the background and use the S Pen for maximum precision on Note and Ultra models. Pen strokes are recognized as handwriting, which is useful for taking notes.
On Google Pixel and Motorola smartphones with close to stock Android, the interface is more minimalistic. The main functions are hidden in the "Share" menu, where among the sharing options there is often a "Markup" option. This saves space on the screen, but requires unnecessary action.
Owners of custom firmware, such as LineageOS or Pixel Experience, should know that the functionality can be reduced to a basic level. In such cases, installing a third-party application is the only way out for comfortable work with graphics.
Frequent mistakes and tips for optimizing the workflow
When frequently using annotation tools, users make a number of common mistakes that complicate further work with images. The most common one is using a line that is too thin on a bright background.
If you outline an element with a red marker on a red background, the mark will be invisible. Always choose contrasting colors: white or black with a border, bright green or yellow for dark areas. This ensures that the recipient of the message will immediately see the accent.
Another problem is saving in an unsuccessful format. For screenshots with text and diagrams, the best format is PNG, which does not lose quality when compressed. The JPEG format can create artifacts around clear stroke lines, making them blurry.
Recommended format: PNG-24
Not recommended: JPEG (for diagrams and text)
It is also worth organizing the storage of such files. Create a separate "Instructions" or "Tagged Screenshots" album so they don't get lost among thousands of regular photos. Many galleries allow you to automatically sort photos by content type.
Contrast and file format are key parameters for the readability of your annotations. Always check the result before sending.
FAQ: Answers to popular questions
Is it possible to circle an element on a video directly in the gallery?
This function is rare in standard galleries. It is usually possible to take a screenshot from a video and then markup it. However, some advanced editors, like the video editor from CapCut or Samsung's built-in tools, allow you to overlay graphics on top of the video during the editing process.
How to make sure that the stroke does not overlap the text in the photo?
Use the Blur or Pixelate tool for the background under the text, or select a translucent marker. Some applications have an "Outside the Line" mode that blurs everything except the outlined area, making the text inside more readable.
Why does the stroke color change after saving?
This is due to the color profile conversion when saving to JPEG. The sRGB color space may differ from what your screen displays. Try to use standard colors from the editor's palette and save files as PNG.
Is it possible to send a photo with a stroke without saving it to memory?
Yes, many instant messengers (Telegram, WhatsApp, Viber) have a built-in editor. When choosing a photo to send, tap the pencil icon, circle the item, and send. The file will be sent to the interlocutor, but will not be saved in your gallery as a separate edited image.
How can I remove the stroke if I made a mistake?
Most editors have a “Undo” button (back arrow) in the top panel. If you have already saved the file, you can only return it to its original state if a copy has been made. Otherwise, you will have to use the Eraser tool, if it is provided by the application developer.
