Emojis have become an essential part of modern digital conversations, helping users express emotions, ideas, and concepts with a single character. For many iPhone users, emojis add flavor to everyday texting, social media posts, and emails. However, not all emojis appear the same across every device, and in particular, some newer emojis don’t show at all on older iOS versions. This leaves many users confused when they receive strange symbols or blank boxes in place of the expressive icons they expect. But what’s causing this?
TL;DR: New emojis are tied to iOS software updates. When Apple releases new emojis, they’re bundled with new Unicode standards and updated emoji fonts. Older iOS versions don’t recognize these new characters, which is why users see blank boxes or question marks instead. Updating to the latest iOS version is the only way to see and use the newest emojis.
Understanding the Emoji Ecosystem
Emojis are not just cute symbols. They are actually standardized characters encoded by the Unicode Consortium, the organization that assigns a unique code to every character, including emojis, used across global digital platforms. Every year, Unicode releases new emoji recommendations. After that, device makers like Apple, Google, and Samsung design their versions of those emojis and integrate them into their systems via software updates.

When Apple supports a new set of emojis, it updates its iOS operating system to include the new Unicode characters and the matching emoji designs. This means that unless an iPhone is running the iOS version that supports those new emojis, users won’t be able to see or use them.
Why New Emojis Don’t Work on Older iPhones
The inability to see emojis on older iOS versions boils down to two primary reasons:
- Unicode Incompatibility: Each new batch of emojis is tied to a specific Unicode version (such as Unicode 15.1). If an iOS version doesn’t support that Unicode level, it can’t recognize the new emoji characters, leading to blank boxes or question marks.
- Missing Emoji Fonts: Even if you somehow send or receive a Unicode emoji that the OS technically recognizes, the operating system still needs the right font file—or emoji rendering engine—to display it correctly. Older iOS versions lack these updated fonts.
So in essence, there needs to be both recognition of the character code through the Unicode standard and proper rendering capabilities through updated fonts. That’s why even copying and pasting new emojis into an old iOS device doesn’t magically make them visible.
How Software Updates Solve the Problem
Apple updates iOS frequently not just to improve performance or security, but also to introduce new features—including emojis. Each emoji-related update includes:
- Support for new Unicode characters
- Visual assets for rendering those characters as images
- Bug fixes that improve emoji consistency
This is why the only sure way to gain access to the latest emoji set is to update the device’s operating system to at least the version that includes them. For example, the “melting face” emoji was introduced in Unicode 14.0 and appeared on iPhones starting with iOS 15.4. Any iPhone running an earlier version wouldn’t see it.
The “Tofu” Phenomenon: Why You See Boxes Instead of Emojis
Users often describe seeing a white or gray box in place of an emoji. This is called a “tofu”—a placeholder symbol shown when a device can’t render a specific character. It’s not a rendering glitch; it’s the system admitting, “I don’t know what this is.”

This can disrupt communication if someone is trying to send context or emotion via a newer emoji to a recipient on an older device. What was supposed to be a laughing face might end up looking like a mysterious black square.
Compatibility Between Devices and Platforms
Another variable in emoji visibility is platform compatibility. Emojis sent from an Android device might appear differently on an iPhone, even if both support the same Unicode version. That’s because each company adds its unique design layer over the Unicode standard. But if an emoji on iOS isn’t supported on the recipient’s Android version—or vice versa—it becomes unreadable.
Cross-platform communication can also be affected when social media platforms like Twitter or WhatsApp implement custom emoji renderers. Although these platforms sometimes bypass system fonts using image-based rendering, device OS compatibility still plays a big role in emoji usability.
What Users Can Do
If someone notices that some emojis aren’t showing up, here are a few things they can do:
- Update the Device: Always ensure the iPhone is running the latest iOS version available for the device model.
- Encourage Friends to Update: If someone sends an emoji and the recipient sees a blank box, it’s likely the recipient needs to update their OS.
- Check Compatibility Guides: Resources like Emojipedia provide breakdowns of which emojis are compatible with which iOS versions.
Why Apple Won’t Back-Support New Emojis in Old iOS Versions
Some users wonder why Apple doesn’t simply offer emoji updates as standalone downloads, separate from full iOS versions. The main reasons are:
- System Integration: Emojis are deeply tied into the operating system’s font management, keyboard, and input logic. Updating them without changing other components could break features.
- Security and Performance: Apple uses emoji updates as incentives for users to stay current. Supporting old systems with new features increases development and QA complexity.
Simply put, updating emojis requires more than just fresh images—it means altering how the system recognizes, interprets, and displays text data.
Conclusion
Emojis are more advanced than many people realize, functioning as internationally coded characters backed by Unicode and rendered specifically by each platform. When a new emoji shows up blank on an older iPhone, it’s because the device lacks the Unicode and font updates required to support it. Since these changes are bundled with iOS updates, users must keep their devices current to enjoy the latest emoji expressions. As digital communication evolves, so too must the tools we use to express ourselves within it.
FAQ
- Why do I see blank boxes instead of emojis on my iPhone?
- This typically means your iPhone is running an older iOS version that does not support the Unicode standard or emoji set for that character.
- Can I install new emojis without updating iOS?
- No. Apple only adds new emojis through official iOS updates, which also update the system fonts and character maps.
- What is a “tofu” emoji?
- “Tofu” refers to the empty box or square that appears when a device can’t render a character, often due to missing font support.
- Will jailbreaking my phone allow me to get new emojis?
- Jailbreaking may offer a workaround, but it poses significant security risks, may void warranties, and can lead to instability and app incompatibility.
- How often does Apple release new emojis?
- Typically once or twice a year, often aligned with Unicode updates and major iOS version releases.
- Can someone on an older iPhone send newer emojis?
- No. They won’t have access to the new emoji keyboard options unless their system has been updated to the version that includes them.
