Putting aside the lack of end-to-end encryption support, one of the most annoying things for Apple iPhone users about communicating with Android users via SMS are all the iOS features that get lost in translation. Having a visual effect translated to a deadpan “(sent with Balloons)” ruins whatever impact you intended the effect to have, and it clutters up your message history with extraneous text.

On that second front, Apple’s Tapback feature is especially annoying. When using iMessage, this short list of half a dozen reactions is a handy way to signal acknowledgement or enjoyment, or just to bump a message thread to the top of someone’s list. On Android phones, each individual Tapback generates an entirely new block of text with a text description of the reaction and the entire original text. As a fallback option for non-smartphones or an accessibility feature, this isn’t necessarily a bad thing. But it can quickly make SMS group-text threads chaotic and unreadable for Android users.
