Almost all smartphone users face the need to enter the underscore character every day. Whether it's creating a complex password, entering a username on a social network, or writing technical text, this sign is an integral part of digital communication. However, on a mobile keyboard it is often hidden deeper than the usual letters and numbers, which causes confusion among beginners.
In this article we will look in detail at how to find and use underscore on different versions of the operating system Android. We'll look at standard input methods via the system keyboard, settings for popular third-party applications, as well as specific cases where this character is required in code or system settings. You will learn where to look for this character on the keyboard Gboard, Samsung and other popular layouts.
Don't panic if you don't see the desired character on the main input screen. The interface of mobile devices is optimized for quick text printing, so special characters are often placed at additional levels. Understanding the logic behind constructing a virtual keyboard will help you instantly find any special characters, including hyphens, slashes and, of course, underscores.
Standard input via a virtual keyboard
The easiest way to add an underscore is to use the built-in keyboard of your smartphone. In the vast majority of cases, this symbol is located on the panel with numbers and punctuation marks. To access it, you need to switch from the letter layout. Typically, this is done using a button ?123 or an icon with a symbol =\<located in the lower left corner of the screen.
After switching, you will see a series of numbers and basic symbols. If the underscore is not immediately visible on this screen, try pressing the =\< or 1/2 button to go to the second page of characters. This is where technical characters such as tilde, backslash and underscore (this is the name of this character in English) are most often hidden.
On some keyboards, long pressing the hyphen button “-” brings up a pop-up menu where you can select the underscore “_” without going to other tabs.
The location of the button may vary slightly depending on the device manufacturer. For example, on smartphones Xiaomi or Redmi the path may be shorter than on devices of other brands. It is important to carefully examine all available tabs with special characters, since developers often change the logic for grouping characters in software updates.
The layout switch button (?123) is the main key to searching for any special characters, including underscores.
Features of the Gboard keyboard from Google
The keyboard Gboard is a de facto standard for many devices based on Android, including the line Pixel and many third-party smartphones. In this layout, the process of entering special characters is as intuitive as possible, but has its own nuances. After pressing the button ?123 you are taken to a screen with numbers, where the underline is usually located in the top row, next to the number 0 or plus sign.
If you do not find the symbol right away, pay attention to the button with an arrow or icon <= in the lower left corner. She opens a second set of symbols. There is also a predictive input function that can suggest frequently used combinations, but for a single character it is better to use manual input. This ensures typing accuracy, especially when entering passwords.

It is worth noting that in the latest updates Gboard Google is experimenting with the placement of rarely used characters. Therefore, if you updated the application recently, do not be surprised if the familiar button has moved to a different place.

Inputting a character on a Samsung keyboard
Owners of devices from the South Korean giant use a proprietary shell One UI and pre-installed Samsung Keyboard. Here the underscore search logic is similar to the standard one, but the visual design of the buttons can be confusing. Switch to symbol mode by pressing the 123button. On the first screen you will see basic punctuation.
Accessing technical symbols, including _often requires you to press a button !#1 or similar located at the bottom left. This will open an expanded set of special characters. In some firmware versions, the underscore is placed on a separate tab, which can be found by swiping the screen left or right in character input mode.
⚠️ Attention: On older firmware versions Samsung the underscore could be hidden inside the menu called by a long tap on the hyphen button. If you don't see a separate button, try this method.
Particular attention should be paid to the input mode in notes applications or browser Samsung Internet. Sometimes the input context affects the available character set. For example, in the URL input field, the keyboard can automatically suggest domain zones and special characters needed for web addresses, making things easier.

If you often use underscores, you can add them to the AutoCorrect dictionary. Go to Keyboard Settings -> Manage Words -> AutoCorrect and create a rule, for example, replacing “nh” with “_”.
Using underscores in HTML and code
For developers and webmasters working with Androiddevices through a terminal or mobile code editors, it is important to understand the difference between a visual symbol and its code representation. In markup language HTML the underscore itself does not create the visual effect of underlining text; it is simply a symbol of the text.
If your task is to visually emphasize text on a web page opened from a phone, you need to use CSS properties. The character _ is used in class names, identifiers, or file names where spaces are not allowed. This is a critically important point when designing responsive websites.
| Context of use | Symbol / Code | Purpose |
|---|---|---|
| Text field (password, login) | _ (Shift + hyphen) |
Word separator in the identifier |
| HTML (visual design) | Text |
Tag for underlining text |
| CSS (styling) | text-decoration: underline; |
Property for underlining |
| File name in the system | file_name.txt |
Replacing a space in the name |
When working with mobile IDEs such as Acode or Spck Editor, the special characters panel is often placed in a separate tool menu. This allows you to quickly insert frequently used designs without having to switch the main keyboard. Knowing the hotkeys or the location of buttons in such applications significantly speeds up the work.

Problems with displaying and entering the character
Sometimes users are faced with a situation where the underscore character is either not entered or is displayed as a square or a question. This may be due to the lack of support for this glyph in the used font or specific application. This problem is more common in specialized apps or games that use a reduced character set.
Another common problem is accidental button press Shift. On some keyboards, when active Shift the hyphen button turns into an underscore, but if the layout is confused, you can enter other characters. Always keep an eye on the register indicator on the screen. It is also worth checking whether the number-only input mode is enabled, which blocks the entry of special characters.
⚠️ Attention: If a character is not displayed in a specific application (for example, in a game), try copying it from another source (browser or notes) and pasting it through the clipboard. This will bypass the limitations of the app's internal keyboard.
In rare cases, the problem lies in the system font file itself Android. If you installed custom fonts or themes, they may not contain the full character table Unicode. Reverting to the system default font usually resolves this issue instantly.
To quickly insert repeating characters, use the Clipboard feature in Gboard's keyboard settings. You can pin the “_” character in the buffer and paste it with one tap.
Alternative methods and third-party utilities
If standard methods for some reason do not suit you, there are many third-party solutions. App stores offer rich keyboards, programmable macros, and specialized panels for developers. Applications like Hacker's Keyboard provide a full PC layout right on the smartphone screen.
In such keyboards, the underscore is available directly, as on a physical computer keyboard, usually in a row with numbers. This is ideal for those who often write code or work with configuration files on their phone. Installing such an application requires granting permissions to access input, which is standard procedure.
In addition, you can use voice input. Although dictation of the "underscore" character does not work in all language packs, in English mode Google Assistant or the built-in voice recorder, the "underscore" command is often recognized correctly. This can be useful if one hand is occupied and you need to enter a character.
⚠️ Note: Application interfaces and button layouts may change with software updates. If the path described does not match your screen, check the Help section in your keyboard settings or refer to the device's official user manual.
Frequently asked questions (FAQ)
Why is there no underscore button on my keyboard?
You are most likely on the first page of characters. Press the toggle button (usually =\< or arrow) on the numbers screen to go to the second page where the technical symbols are located. Also check your keyboard language settings.
Is it possible to make the underscore longer?
In a regular text field, you can put several characters in a row (___). If you need to graphically underline text, this is done through formatting (tag <u> in HTML or text style in editors like Word), rather than by repeating a character.
How to enter an underscore if the keyboard is frozen?
Try switching to a different keyboard in your phone settings (Settings → System → Language and input). If the problem persists, restart your device. As a last resort, copy the character from the browser and paste it.
Where is the underscore on the iPhone if I switched from Android?
On iOS the logic is similar: press the 123button, then the #+=button. The symbol _ is usually found on this second page of symbols in the bottom row.
Is it mandatory to use underscores in passwords?
No, this is not a mandatory requirement for all services. However, the use of special characters, including _, significantly increases the strength of the password and makes it more difficult for attackers to guess.
