WhatsApp custom emoji reactions iPhone: how it would work

References to WhatsApp custom emoji reactions for iPhone have turned up in WhatsApp for iOS beta version 26.32.10.16, hinting that the app may eventually let iPhone owners swap out its six standard reaction icons for their own picks (WABetaInfo, last week). Right now, every iPhone user sees the same fixed lineup, 👍, ❤️, 😂, 😮, 😢, and 🙏, when they long-press a message, with no built-in way to change it (Cult of Mac, today). The reference surfaced in that TestFlight build, though the feature isn't enabled for any tester yet (Cult of Mac, today).

Nearly all of this WhatsApp iOS beta custom reactions reporting traces back to one source. WABetaInfo dug the code references out of the build, and 9to5Mac, MacObserver, and Cult of Mac have largely echoed rather than independently confirmed the findings, including the claim that the feature may be reserved for WhatsApp Plus subscribers (9to5Mac, last week). Treat the premium angle as reported, not established.

How WhatsApp's default reactions setting would work

WABetaInfo found references to a "Default reactions" setting in the TestFlight build that would give users a dedicated screen, reached through app settings, for building a personalized reaction tray (WABetaInfo, last week). Cult of Mac frames the goal of that screen as letting people build a tray that actually matches how they text (Cult of Mac, today), though that description comes from the outlet's reporting rather than a WhatsApp statement.

It helps to separate three things that currently look similar but work differently. The six standard icons are the first row anyone sees on long-press. Behind those sits a horizontally scrollable strip of commonly or recently used emoji, which already varies somewhat by user. Beyond that is the full emoji keyboard, opened by tapping the "+" button, which is where anyone has to go today to react with anything outside the fixed six (9to5Mac, last week). So far, the reporting describes a setting that touches only the first of those three, letting users replace the six fixed defaults with emoji of their choosing. It does not describe any change to the recently-used row or the keyboard itself, and there's no indication the tray would grow beyond six slots.

Users would reportedly be able to replace one, several, or all six defaults with emoji pulled from the full keyboard, and restore the original set at any point (9to5Mac, last week). That's a narrow, specific change: which six icons appear first when someone long-presses a message, not a redesign of how reactions work.

How to change WhatsApp reaction emojis on iPhone: not possible yet

There's no way to do this today. The setting is inactive for all beta testers, including those running the TestFlight build in which WABetaInfo found the references (9to5Mac, last week).

WABetaInfo reports that the custom reaction tray is being built specifically for WhatsApp Plus subscribers, as part of what it calls the "second set" of premium features (WABetaInfo, last week; Cult of Mac, today). If that reading holds, the feature would give WhatsApp Plus subscribers a faster way to reach preferred emoji than everyone else gets. WhatsApp has not confirmed that limitation, named WhatsApp Plus as an official subscription tier, or announced a release date for either the reaction tray or the premium features it's reportedly bundled with (WABetaInfo, last week).

That leaves the premium framing resting entirely on one outlet's reading of unreleased code. It's worth watching, not treating as settled.

Limited context: WhatsApp's Status reaction precedent

A distinct, older change is worth keeping apart from this one. WhatsApp began rolling out an iOS Status reaction sticker to some beta testers in late 2025, letting Status creators pick any emoji, rather than a fixed icon, as the default reaction prompt displayed on their shared images or videos (WABetaInfo, last year). That system works nothing like message reactions.

Viewers of a Status update normally swipe up to choose from eight preset emoji, an extra step the sticker was designed to skip by putting one chosen emoji directly on the screen (WABetaInfo, last year). It's a narrow precedent for WhatsApp personalizing emoji choices on iOS, not evidence that the message-reaction tray discovery will ship, or ship in the same form.

What this means for iPhone users right now

There is currently nothing to enable or install. The feature exists only as code references inside an inactive beta build, and neither WhatsApp nor any of the outlets covering it has described a testing rollout, let alone a public launch.

If it does ship, the practical upside is straightforward: pinning a go-to emoji to the long-press menu instead of digging through the full keyboard every time, with the option to restore the default six if the swap doesn't stick (9to5Mac, last week). That's a small change in mechanics with an outsized effect on how often people actually use the reaction they mean, rather than whichever of the six is closest at hand.

What remains open is whether it launches free or Plus-only, when it arrives, and whether the tray stays capped at six positions (WABetaInfo, last week). Those three unknowns are what separate a code reference from a feature anyone can actually use, and none of them have answers yet.

What to watch next

The clearest near-term signal is whether WhatsApp flips the "Default reactions" setting on for any beta tester. That would confirm the feature has moved past internal code and into something people can actually try, which hasn't happened at any point in this reporting so far (WABetaInfo, last week).

A second signal is any direct statement from WhatsApp or Meta, either about the reaction tray itself or about WhatsApp Plus as a formal offering. Everything written about Plus to date comes from beta-tracking outlets working off code, not from the company.

A third is whether the setting eventually surfaces in a stable release rather than staying confined to TestFlight builds, since beta references don't always make it to production unchanged or on any predictable schedule. Until one of those three things happens, the feature remains a documented possibility rather than a product.
