WhatsApp is preparing to end support for Android 5.0 and 5.1 devices in September 2026, while separately testing AI agent chats on Android.
WhatsApp is set to end support for Android 5.0 and 5.1 in September 2026, which means phones stuck on those versions would no longer be able to keep using the app. The change affects older Android hardware that cannot upgrade past Android 5.1, while iPhones are not part of this cutoff and Android 6.0 or newer remains supported for now. Separately, WhatsApp is also testing third-party AI agent chats on Android, but that feature is still limited to a small group of users in select countries.
September 2026 is the Android 5 cutoff
For operators still running WhatsApp on aging handsets, the practical issue is simple: devices that top out at Android 5.0 or 5.1 are heading toward a hard stop in September 2026. Once support ends, those phones would lose ongoing access to WhatsApp, making this less about a minor compatibility warning and more about device replacement planning. Newer Android phones are not the target here, and the current baseline still covers Android 6.0 and later.
That makes the at-risk pool relatively specific. It is older hardware that cannot move beyond Android 5.1, not the broader Android base and not iPhone users. For businesses that still keep legacy phones in the field for support, sales, routing, or line-specific WhatsApp use, the immediate takeaway is to check OS versions now, update devices where possible, and back up chats before the cutoff arrives.
Third-party AI agents move into a limited Android test
The separate product change is a new third-party AI agent system inside WhatsApp for Android. Instead of dropping an agent into an existing thread, WhatsApp is testing a model where each agent opens in its own dedicated conversation. That keeps the feature closer to a separate contact or assistant chat than a layer added across normal inbox activity.
Setup appears to sit inside an Agents area in settings. From there, users can assign the agent a name, add a profile picture, and generate an API key to link the external service to WhatsApp. The feature has been spotted in WhatsApp beta for Android version 2.26.35.3, but access remains very limited, with only a small number of Android users in select countries able to try it so far.
The limits still matter for operators
The boundaries around the agent test are as important as the feature itself. It is not broadly available yet, and rollout timing beyond this early Android test remains unclear. Group chats and communities are not expected to support agents, which narrows the immediate use case to one-on-one agent conversations rather than team threads or shared customer handling flows inside group spaces.
WhatsApp is also designing the feature so agents stay isolated from a user's other chats, contacts, and media. That separation helps define the tool as a contained conversation surface rather than a bot with wide account access. At the same time, the privacy and data-handling model is still not fully explained, so operators considering future use will need clearer detail on message handling and developer access before treating the feature as deployment-ready.
For now, the two developments serve different planning horizons. The Android 5 cutoff is a concrete compatibility deadline for anyone still depending on old phones, while the third-party agent feature is an early Android test worth watching rather than a tool most teams can use today.
