Modern correspondence in messengers has long ceased to be just an exchange of text messages. Emoji have become a full-fledged language of emotions, allowing you to convey your mood without unnecessary words. However, users often face an annoying problem: having sent a beautiful message from a new iPhonesmartphone, they receive in response a question about what these strange squares or empty spaces on the recipient’s screen mean with a Androidsmartphone.
This situation arises due to fundamental differences in approaches to updating system fonts between ecosystems Apple i Google. While the Cupertino company introduces new characters along with major updates, the world is much more fragmented. Manufacturers of smartphones based on a green robotic operating system depend on their own schedules for releasing updates and supporting specific models. iOS, world Android much more fragmented. Manufacturers of smartphones based on the green robotic operating system are dependent on their own schedules for releasing updates and support for specific models.
In this article, we will take a closer look at the technical side of the issue, explain why “squares” appear instead of smiling faces, and consider ways to minimize this problem when communicating between different platforms. Understanding the mechanism of operation Unicode will help you avoid awkward situations in business and personal correspondence.
Technical nature of the problem: the Unicode standard and fonts
All modern emoticons are based on the international character encoding standard Unicode. This consortium regularly releases new versions, adding hundreds of new characters to the table, including emoji. When Apple releases a new version iOS, it immediately implements support for the latest version of the standard in its system fonts.
However, the presence of a character code in the standard does not guarantee its display on the screen. In order for the user to see the picture, the operating system must have a corresponding graphic file - a glyph. If the message code contains a character that is not in the font of the receiving device, the system displays a stub. Most often it is an empty square, a question mark in a diamond, or just a space.
Androiddevices are updated unevenly. Flagship models from Samsung or Google Pixel can get support for new emoji quickly, while budget smartphones or models from previous years often remain on the old version of system fonts for years. That is why the emoticon that you just sent from iPhone 15may not be displayed on Androidthat was released just two years ago.
⚠️ Attention: Even if both smartphones are connected to the same messenger, such as WhatsApp or Telegram, the display of emoticons depends on the system font of the device, and not on applications. Messengers use native operating system resources to render text.
The version support gap Unicode is the main reason for incompatibility. Apple often introduces draft versions of the standard or its own variations even before their official approval, which creates a time gap during which characters remain invisible to the rest world.
Main types of invisible symbols and their manifestations
Not all display problems look the same. Depending on the version of the operating system and the specific messenger, the user Android may see different artifacts instead of the emotions you sent. Understanding the type of error will help determine the degree of obsolescence of the software on the interlocutor’s device.
The most common phenomenon is the appearance of so-called “tofu” - empty rectangles. This means that the device has received a character code, but its font library does not have a graphic for that code. Less commonly, you can see a question mark in a black diamond, which indicates the complete impossibility of decoding bytes.
Sometimes there is a situation when a smiley is displayed, but it looks completely different from what was intended. For example, a new professional emoji can turn into a regular yellow circle or a strange hieroglyph. This occurs when the character code has been reassigned in new versions of the standard, and the old device interprets it in the old way.
- 🟥 Empty square - the device does not have a glyph for this Unicode code.
- ❓ A question mark in a diamond - a critical decoding error or a broken byte.
- 🔄 Old version of the emoticon - the device uses an outdated version of the Emoji standard.
Particular attention should be paid to complex compound emoji. Symbols consisting of several parts (for example, a family of several people of different races or flags of countries) require support for sequences Zero Width Joiner. Older versions Android often break such sequences into separate parts, showing instead of one family a set of disparate people or just flags.
⚠️ Attention: Some manufacturers, such as Xiaomi or Samsung, may use their own sets of emoji on top of the standard ones. This can lead to the fact that even with the same version of Android, emoticons will look different on different devices.
The influence of iOS and Android versions on compatibility
The key factor in compatibility is the version of the operating system. Apple supports its devices for quite a long time, but new emoji functions are available only on current versions iOS. The situation is similar in the camp Android, where support depends not only on the kernel version, but also on the manufacturer’s shell.
Below is a table showing the approximate correspondence between operating system versions and supported versions of the emoji standard. This data will help you understand why a particular emoticon may not work for your interlocutor.
| Emoji standard version | Minimum iOS version | Minimum Android version | Year of release |
|---|---|---|---|
| Emoji 15.1 | iOS 17.4 | Android 14 (partially) | 2023 |
| Emoji 15.0 | iOS 16.4 | Android 13 | 2022 |
| Emoji 14.0 | iOS 16.0 | Android 12L / 13 | 2021 |
| Emoji 13.1 | iOS 14.5 | Android 11 | 2020 |
| Emoji 12.0 | iOS 12.1 | Android 10 | 2019 |
As can be seen from the table, the gap can be several years. If you use iOS 17, and your interlocutor is sitting on Android 10, he is guaranteed not to see most of the new emoticons that have appeared over the past three years. Updating the system on Android does not always solve the problem if the device manufacturer has stopped supporting the model.
Owners iPhone should take into account that even within the ecosystem Apple there may be nuances. Older models that are not updated to the latest iOSwill also show squares when receiving new symbols from friends with the latest devices. This is a universal problem of digital inequality of software versions.
The main reason for invisible emoticons is that the recipient's version of Android lags behind the version of the Unicode standard implemented in your iPhone.
Specific cases: flags, professions and gender
The greatest difficulties are caused not by simple yellow faces, but by compound characters. Country flags are encoded not as one picture, but as a pair of special symbols of regional indicators. If the device does not support this logic, instead of the German flag you will see two letters D and E or two separate placeholder flags.
The situation gets worse with the introduction of gender-neutral options and diversity of professions. Emoticons that allow you to select a character's gender or occupation use complex sequences. On older Androidsmartphones, a female doctor can turn into just a woman and a separately hanging stethoscope icon, which completely changes the meaning of the message.
New skin colors deserve special mention. The skin tone modifier mechanism works stably on relatively recent devices, but on systems older than 2018 it often breaks down. Instead of a dark-skinned character, you can see the standard yellow man standing next to a colored square, which should have changed his tone.
Why are flags unstable?
Flags are encoded using a sequence of two regional indicator characters (for example, US for the United States). If the device font is not configured to combine these two characters into one glyph image, they appear as two separate letters or icons. This is a common problem on custom Android firmware.
It is also worth noting the problem with so-called “custom” stickers and effects. iMessage allows you to send animated effects and stickers that are not part of the standard at all Unicode. They work only within the ecosystem Apple. When sending such a message to Android (via SMS or some instant messengers), the recipient will see only a text description of the effect or emptiness.
The role of messengers in displaying emoji
Although basic support depends on the operating system, popular instant messengers are trying to smooth out the corners. Apps like Telegram and WhatsApp use their own font sets or load emoji images from their servers to ensure consistent display across all platforms.
V Telegram, for example, a system has been implemented in which emoticons are rendered by the application itself, almost regardless of the version Android. This means that even on a very old phone, you will most likely see the desired emoji if the application is updated. However, this does not work for all symbols, especially for the most recent innovations.
WhatsApp occupies an intermediate position. The application strives to use system fonts, but has its own set of fallback images. However, if you send the newest emoticon from iOSthat has not yet been added to the server database WhatsApp, users Android may see a stub until the application is updated on their side.
- 📱 Telegram is the least dependent on the OS version, uses its own fonts.
- 💬 WhatsApp - depends on updating the emoji database inside the application.
- 💌 iMessage - full compatibility only between Apple devices.
It is important to understand the difference between sending via SMS/MMS and Internet instant messengers. In classic text messages, the incompatibility problem is most acute, since it uses exclusively the system font without any backup from the application.
⚠️ Attention: Details of the display of emoji in instant messengers may change with each application update. Developers are constantly adding support for new characters, so what didn’t work a month ago can work today after an update.
☑️ Checking correspondence compatibility
Practical tips for comfortable correspondence
To avoid misunderstandings in correspondence with users Android, it is worth adhere to certain rules of etiquette and technical safety. The main rule is not to rely on the newest symbols if you are not sure that the interlocutor’s software is up-to-date.
If it is critically important for you to convey an emotion, use time-tested classic emoticons that have been standard for 5-7 years. They are guaranteed to be displayed on any device, from ancient Android 6 to the latest iPhone. Avoid complex compound structures in important messages.
In cases where you need to send a specific new character, you can duplicate its meaning with text in brackets. For example: “I’m so happy for you! [fireworks emoji].” This will save the interlocutor from guessing what the appeared squares mean, and will preserve the emotional color of the message.
Before an important mailing, send a test message with new emoticons to your old spare phone or ask a friend with Android to check the display. This will save nerves and prevent embarrassment.
It is also recommended to regularly update the messengers themselves. Developers often release patches that add support for new glyphs at the application level, which allows you to bypass system font restrictions Android. Go to Settings applications and check for updates.
Frequently asked questions (FAQ)
Is it possible to install new emoticons on old Android manually?
Yes, it is possible, but requires obtaining root access. Users can replace the system font file NotoColorEmoji.ttf with a newer version downloaded from current devices or third-party repositories. However, this is a risky procedure that can lead to unstable operation of the system or loss of warranty.
Why are emoticons visible in WhatsApp, but not in SMS?
WhatsApp and other Internet messengers use their own rendering mechanisms and often load emoji pictures from the network or use built-in system-independent sets. SMS relies solely on the standard font installed in your phone's firmware.
Does the region of your phone settings affect the set of emoticons?
The Unicode standard itself is global, but some manufacturers may hide or replace certain characters depending on regional settings or firmware localization. For example, some specific characters may not be available in software versions for certain countries.
When will Android completely catch up with the iPhone in terms of the set of emojis?
Full synchronous matching is unlikely to be achieved due to the fragmentation of the Android market. However, with the release Android 14 and implementation of updated modules Google Play System Updates, the gap is closing, and many new emoticons are becoming available faster than before.
What to do if the interlocutor sees a hieroglyph instead of an emoticon?
This means that the character code was reassigned in the new version of the standard, and the interlocutor’s device interprets it according to the old table. In this case, only updating the operating system on the recipient's device or using a text description of the emotion will help.
