Rcs 4.0 lands with video calls and crypto, but users just want the blue bubble to die
44 % of 665 people polled by PhoneArena don’t care about HD video, stronger spam shields or even cross-platform encryption. They want one messaging app that works for everyone, everywhere, right now. The stat is a slap in the face to every carrier slide-deck that promised RCS would “fix” texting.
Apple sits on 2.4 while the world races to 4.0
Google flipped the switch on RCS Universal Profile 4.0 last week, packing native 1080p calls, 8 000-character group threads and enterprise-grade scam filters. The GSMA calls it the biggest upgrade since Rich Communication Services was christened in 2016. Yet Apple’s iPhones still speak version 2.4, a spec frozen when the iPhone 12 was news. The lag is not a technical hiccup; it’s a retention strategy. Internal Apple emails revealed in the Epic trial show executives calculating that opening iMessage to Android would “remove a barrier” to leaving the ecosystem. Translation: the lock-in is deliberate.
Google isn’t innocent. It has whipsawed users through Allo, Hangouts, Duo, Meet and now RCS, each launch promising “this time it’s unified.” The body count of dead messaging apps is why even Android loyalists greet RCS 4.0 with a shrug. Still, the search giant has shipped every new profile within months; Apple won’t commit to a 3.0 roadmap, let alone 4.0.
Encryption sounds sexy until no one can read your text
Only 26 % of respondents called end-to-end encryption their deal-breaker. That number feels large until you realize Apple’s test builds of encrypted RCS live only in the iOS 26.4 beta, disabled by default and missing in the public release notes. Cross-platform crypto is Schrödinger’s feature: simultaneously promised and unavailable. Without Apple’s participation, RCS messages between iPhone and Android fall back to the same old SMS-style packet, readable by carrier servers and friendly NSA analysts alike.
The remaining 30 % split between built-in video calling (20 %) and spam filters (9 %). Both already exist in standalone apps that work today. WhatsApp, FaceTime, Google Meet and Signal deliver crisp video and zero-day scam detection without waiting for carriers to flip a bit. Users know this, and they vote with their apathy.
The business model is the bug
RCS was conceived as a carrier play to claw back revenue lost to WhatsApp and iMessage. Every “enhanced” text rides the SMS billing rails, giving telecoms a reason to cheer. Apple, meanwhile, monetizes differentiation: blue bubbles sell phones and watches, and exclusive Memoji stickers keep families locked into iCloud subscriptions. Google profits by keeping Android users inside its own ad stack. No one earns a dime from true interoperability, so fragmentation is baked into the P&L.
Regulators in Europe and India are nibbling at the edges—forcing USB-C ports, sideloading gates, default browser ballots—but messaging remains untouched. Until an antitrust ruling treats iMessage like a utility, Apple will continue to treat RCS as a courtesy guest star rather than a cast member.
The brutal truth: the protocol isn’t broken; the incentives are. RCS 4.0 could launch tomorrow on every iPhone and Android device simultaneously, and most users would still need WhatsApp to reach their cousins in São Paulo, WeChat for business in Shenzhen and Telegram for the group trip to Lisbon. The dream of a single inbox died not from lack of Technology but from an excess of quarterly earnings calls.
So we keep three apps on the home screen, battery gauges dipping under the weight of redundant notifications. The next great messaging revolution won’t come from a spec sheet. It will come the day a CFO decides lock-in costs more than openness. Don’t hold your breath; the spreadsheets say that day isn’t in this fiscal year.
