Apple is currently testing end-to-end encrypted messaging between iPhones and Android devices in the first developer beta of iOS 26.5. This feature was initially pulled before the release of iOS 26.4 but is now making a comeback.
What’s Being Tested
The feature in focus is end-to-end encryption (E2EE) for RCS messages. RCS, or Rich Communication Services, is the modern texting standard that replaces the older SMS system. It adds features like read receipts, high-quality photo sharing, and typing indicators. Apple introduced RCS support for iPhones in 2024, but messaging between iPhones and Androids lacked the privacy protections found in iMessage chats between two iPhones.
End-to-end encryption ensures that only the sender and recipient can read a message. Not Apple, not Google, and not your carrier can access it. You can think of it like a sealed letter that only you and your recipient can open. Without this encryption, RCS messages between iPhone and Android are akin to postcards that anyone handling them could potentially read.
Apple first tested this encryption during the iOS 26.4 beta but later confirmed it wouldn’t be included in that update. Now, with iOS 26.5 beta 1 available to developers since March 30, 2026, the encryption code has returned, as reported by 9to5Mac.
Why This Took So Long
Implementing encryption across iPhone and Android isn’t as simple as flipping a switch. The two platforms rely on different software ecosystems, requiring both sides to agree on and implement the same encryption standard. The standard in use is part of the broader RCS Universal Profile specification, which the GSMA, an industry body, has been working on to include E2EE across all carriers and devices.
Apple has traditionally kept iMessage exclusive to Apple devices due to its robust encryption. Extending similar protection to cross-platform RCS chats involves collaboration with Google, which manages the RCS infrastructure on Android, as well as wireless carriers worldwide. The fact that Apple has moved this feature into a second beta cycle indicates that the technical groundwork is likely in place, although it’s not yet ready for public release, as MacRumors noted.
What Else Is New in iOS 26.5
The RCS encryption feature isn’t the only interesting development in iOS 26.5 beta 1. Apple is also testing Live Activities support for third-party accessories in the European Union. Live Activities are real-time notifications that show up on your iPhone’s lock screen and Dynamic Island, displaying updates like sports scores or food delivery countdowns. This EU expansion would allow accessory makers—think smart home devices or fitness trackers—to utilize that same display system, which is currently limited to apps on the iPhone. This change aligns with the EU’s Digital Markets Act, requiring Apple to open more of its platform to third-party developers in Europe, according to 9to5Mac.
| Stat | Detail |
|---|---|
| iOS 26.5 Beta 1 Release | March 30, 2026 |
| Previous Beta Test | iOS 26.4 beta (feature did not ship) |
| Encryption Standard | RCS Universal Profile E2EE (GSMA spec) |
| Platforms Affected | iPhone to Android RCS conversations |
| Additional Feature | Live Activities for third-party accessories (EU only) |
What This Means
If this feature launches, it would enhance privacy for anyone texting between iPhones and Android phones. This covers a significant share of everyday conversations, especially in the U.S., where iPhone usage exceeds 55 percent. Currently, those green-bubble chats lack true privacy. Once E2EE is implemented for RCS, your messages to Android-using friends, family members, or coworkers will enjoy the same basic privacy protections as iMessage. You won’t need to switch to a third-party app like Signal or WhatsApp for encrypted messaging—it’ll work seamlessly in the default Messages app.
What People Are Saying
“Finally. I’ve been telling my parents to use WhatsApp for years just because iMessage doesn’t encrypt cross-platform. If this ships, it’s a huge deal for normal people who don’t want to manage five different apps.”
“Apple tested this in 26.4 and pulled it. The fact that it’s back in 26.5 is a good sign, but I’ll believe it when I see it in the release notes.”
What To Watch
- iOS 26.5 beta cycle: Additional developer betas will be released in the coming weeks. Keep an eye out for whether Apple removes the RCS encryption code again or continues refining it toward release.
- WWDC 2026: Apple’s annual developer conference is anticipated in June 2026. The company could officially announce RCS E2EE as a completed feature if testing goes well.
- Google’s response: For this to function on Android, Google’s Messages app must also support the same encryption standard. Any announcements from Google regarding RCS E2EE compatibility will be a key indicator that a public launch is nearing.
- EU Live Activities rollout: If the accessory Live Activities feature launches in Europe, it could hint at whether Apple plans to extend similar openness to other markets under future regulatory pressure.
