An empty square, a question-mark box, or a crossed-out box usually means the emoji is present in the text but the current font or app cannot draw it. The cause may be an older operating-system emoji font, an app that does not support a newer or combined sequence, or a compatibility gap on the recipient’s device. Start by checking where the box appears: while you type, in one app, across several apps, or only after sending. That pattern is more useful than assuming your phone is outdated or physically damaged.
At a glance
| Symptom | Likely cause | First fix |
|---|---|---|
| Boxed across Apple apps | iOS font or system-level support does not recognize that character or sequence | Install any available iOS update, then test an older, single emoji |
| Correct in Notes or Messages, boxed in a third-party app | That app’s text renderer or emoji support is limited | Update the affected app and compare with a basic text field |
| Correct on your iPhone but boxed for the recipient | The recipient’s device, operating system, or app lacks support | Describe it in words or send an image or sticker |
| Box appears while typing or the emoji is missing from the picker | Keyboard configuration or keyboard implementation issue | Check the Emoji keyboard; refresh Gboard only if its picker or suggestions are wrong |
| Looks correct before sending, then becomes a box afterward | The sending app or recipient cannot render the character or sequence | Check the sent copy in another app and ask the recipient what they see |
| Only one emoji, flag, skin-tone combination, or joined sequence fails | That newer code point or multi-character sequence is unsupported | Update the operating system and app; use a simpler emoji if needed |
| Fails everywhere on one phone | Device-wide font or software compatibility limitation | Install system updates and test on another device before changing keyboards |
What does a square or question-mark box mean?
It is commonly called a missing-glyph or “tofu” symbol. Unicode explains that when text contains a character for which the active font has no glyph, software may draw a white square, a question-mark box, or a box with diagonal marks instead. The box is evidence of a rendering failure, not proof that the message is corrupt or that the phone is broken. See Unicode’s explanation of display problems.
Emoji are Unicode characters assigned to code points and then drawn by an operating-system or app font. Google’s explanation of the “weird box next to my emoji” describes this code-point-and-font relationship and why app compatibility matters on Android: Google’s emoji rendering explainer.

- Check the picker. Is the emoji missing from the keyboard, or does it appear in the picker but turn into a box when inserted? If it is absent from the picker yet displays when pasted, the keyboard and the display font are separate issues.
- Watch while typing. Does it appear as a box while you type? Test the same character in a basic text field such as a new note. If the basic field is correct, the original app is the likely problem.
- Compare apps. Compare Notes, Messages, and the original app that supplied the text. A character that is correct in Notes or Messages but boxed in a third-party app points to that app’s renderer. Conversely, if it is boxed across Apple apps, investigate iOS-level support.
- Inspect the sent copy. Does it look correct before sending but become a box afterward? The sending app may transform or fail to preserve the sequence, or the recipient may be using an older renderer.
- Ask whether it is selective. Does only one emoji, flag, skin-tone combination, or joined sequence fail? Selective failure usually indicates support for that newer code point or sequence, not a dead keyboard.
- Check scope. If it fails everywhere on your device, install available software updates and test another device. If only one app fails, update or troubleshoot that app before changing system settings.
This comparison is a diagnostic inference, not a guarantee: fonts, app renderers, and message services can each affect the result.
Why do newer or combined emojis turn into boxes?
Emoji support is version-dependent. A phone may render older single emoji while lacking a newer addition. Combined emoji add another compatibility requirement: the individual characters may be supported, but the app may not know how to render the complete joined sequence. Unicode’s current emoji specification illustrates sequences joined with a zero-width joiner; see the Unicode Emoji specification update.
Flags, skin-tone variants, family or profession combinations, and other joined designs are therefore useful tests. Try a plain, older emoji beside the failing one. If the plain symbol works and the combination does not, update the operating system and affected app, then use the plain symbol or a written description when compatibility cannot be improved.

How do I fix missing emoji on Android?
Android fixes depend on the operating-system version and the app’s text technology. Work through these steps in order:
- Update the affected app. Open Google Play, view the app’s updates, and install the current release. Test the emoji in another app and in a basic text field after updating.
- Install device software updates. Use your phone’s Settings software-update screen. A newer system may include an updated emoji font, but an update is a sensible check rather than a guaranteed cure.
- Understand the Android version boundary. Android’s Jetpack Compose documentation states that Android 11 (API level 30) and earlier cannot update the emoji font through the system mechanism described there. Apps using that approach must provide their own manual compatibility updates for later emoji. The platform guidance is documented in Android’s Compose emoji documentation.
- Check app-level compatibility. Android’s Emoji2 library is an app-level path for supporting newer emoji on compatible devices. If one app works and another does not, the difference may be whether and how that app implements such compatibility support; see Android’s Emoji2 documentation.
- Refresh the keyboard only when appropriate. Refresh Android’s keyboard, including Gboard, when the picker or suggestions are wrong, an emoji is missing from the picker, or insertion itself fails. If the emoji is boxed in every app after insertion, repeatedly changing keyboards will not replace the system or app font that draws it.
Do not install random font apps or system modifications as a universal fix. They can introduce security and compatibility problems, and the documented causes do not require them. If the emoji works in the basic app but not the original app, keep the system unchanged and focus on updating that app or reporting its rendering bug.
How do I fix boxes on an iPhone?
First decide whether the keyboard is missing or the displayed character is unsupported. Restoring the keyboard helps only when the Emoji keyboard itself is absent.

- Update iOS. Open Settings, choose General, then Software Update, and install an offered release that your iPhone supports. Apple’s release history includes new emoji and emoji-specific fixes, so availability depends on the model and release: Apple’s iOS update information.
- Update the affected app. If the box appears in one third-party app but not Notes or Messages, update that app and test again. A failure boxed across Apple apps is more consistent with system-level support than with a single app.
- Restore the Emoji keyboard only if it is absent. Follow Apple’s path: Settings > General > Keyboard > Keyboards > Add New Keyboard > Emoji. This restores the keyboard for typing; it does not make an unsupported received emoji render correctly. Apple documents the exact path at Add or remove keyboards on iPhone.
- Compare Notes, Messages, and the original app. Paste the same character into a new note, a message draft, and the app where you first saw it. If it is correct in Notes or Messages but boxed in a third-party app, the third-party renderer is the practical focus.
Do not assume every box means the iPhone is outdated, and do not assume the phone is physically broken. A single newer sequence can fail on an otherwise current device, while an app-specific issue can affect only one screen.
What if the recipient sees a box but I do not?
If the emoji is correct on your iPhone but boxed for the recipient, your device has rendered it successfully; the recipient’s device or app may lack the required character or sequence support. This is especially likely with newer emoji, flags, skin-tone combinations, or joined sequences.
Ask the recipient to check the same message in another app and install available system and app updates. Until both sides support the sequence, use a short description in words or send an image or sticker when that fits the conversation. A message that looks correct before sending but becomes a box afterward can also reflect the sending service’s handling of the sequence, so compare the sent copy rather than relying only on the compose window.

When should I change the keyboard?
Change or refresh a keyboard only when the keyboard is the failing stage. If the emoji is missing from the picker, typing inserts the wrong character, or Gboard’s picker and suggestions are incorrect, update or refresh Gboard and test again. On iPhone, restore the Emoji keyboard only if it is absent.
If the same emoji is boxed in every app, do not keep changing keyboards. The keyboard supplies characters; the operating-system font and each app renderer draw them. Concentrate on system and app updates, version compatibility, and a fallback symbol instead.

What is the safest fallback when compatibility cannot be fixed?
Use an older single emoji that all participants can see, write the meaning in words, or send an image or sticker. When only a combined sequence fails, separating it into simpler symbols may communicate the same idea. Keep the original text if its meaning matters, because replacing it with a visually similar character can change the message.

Document the exact emoji, your operating-system version, the app name and version, and whether the problem occurs in Notes or another basic text field. That information lets the app developer distinguish a renderer defect from a missing system glyph.
Frequently Asked Questions
Why do emoji show as boxes in only one app?
That app may use a different text renderer or may not include compatibility support for newer emoji. Update the app, then compare the same text in a basic text field; if other apps render it correctly, report the issue to the affected app’s developer.
Can reinstalling the keyboard make a missing emoji display?
Only when the keyboard itself is the problem, such as a missing picker or broken suggestions. A keyboard does not supply the glyph used to draw received text, so reinstalling it will not generally fix boxes that appear in every app.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsWhy does a flag or skin-tone emoji fail while ordinary emoji work?
Those designs can be sequences made from multiple code points, and support for each part does not guarantee support for the complete sequence. Install available system and app updates, or use a simpler emoji or words when the combination remains unsupported.
Is a box proof that my phone needs replacing?
No. A single newer character can exceed an app or operating system’s emoji support even on a functioning phone. Check the same text in multiple apps and on another device before considering hardware service.
