Some emoji characters might not display correctly on these devices:
- An iOS device or Mac that's not up to date
- An iOS device that's on another carrier's network
- A non-Apple device (such as an Android, Windows, or BlackBerry tablet or phone)
If recipients have an iPhone, iPad, or iPod touch with iOS 8.2 or ealier, or a Mac with OS X 10.10.2 or ealier, they might see an unexpected alien character. This can happen when the sender changes the skin tone of emoji in iOS 8.3 or later. Or recipients might see boxes with a two-letter country code when the sender uses some of the flag emoji in iOS 8.3 or later.
If recipients have a non-Apple device, they might see blank spaces, boxes, equal signs, question marks, or line breaks when they get a message from someone using an Apple device. This depends on how the recipient's device handles emoji.
