Samsung Galaxy S26 Update: Why the 'Hey Plex' AI Assistant Feature Was Removed

Samsung's newest flagship lineup, the Galaxy S26 series, arrived with a suite of advanced AI capabilities designed to outshine its predecessors. Among the most talked-about additions was the integration of the Perplexity AI assistant, which allowed users to trigger the service using the "Hey Plex" voice command. However, early adopters have noticed a surprising change following the device's very first software update: the convenient voice-activation feature for Perplexity appears to have vanished entirely.

The Disappearance of 'Hey Plex' Detection

When the Galaxy S26 Ultra first hit the market, it boasted a unique advantage over the Galaxy S25 Ultra: the ability to set Perplexity as a primary voice assistant. Within the Perplexity app settings, users could toggle a "Hey Plex detection" switch. Once configured, the phone would instantly wake up and launch the Perplexity interface upon hearing the wake word. This provided a powerful third alternative to Samsung’s own Bixby and Google’s Gemini.

The initial setup process was seamless, allowing the device to recognize the user's voice and integrate the AI tool directly into the daily workflow. Below, you can see the original settings as they appeared when the device was first launched.

Changes After the First Software Update

The situation changed abruptly following the release of the first system update for the Samsung update, which rolled out this past Monday. After installing the patch, users discovered that the "Hey Plex detection" option had been completely removed from the Perplexity app. Consequently, the wake word "Hey Plex" no longer triggers the assistant.

With this modification, the Galaxy S26 series is now restricted to only two hands-free assistants: "Hi Bixby" and "Hey Gemini." While the Perplexity app can still be used manually, the seamless voice integration that was a highlight of the launch experience is currently unavailable. The screenshot below confirms the missing menu item in the updated version of the software.

There is a possibility that Perplexity itself pushed an app update that disabled the feature, though many users do not recall a specific app update occurring simultaneously with the system firmware. It is more likely that the system-level integration was altered in the latest Samsung build. Whether this is due to a technical bug, a licensing shift, or a strategic move to prioritize Gemini and Bixby remains to be seen.

What was the "Hey Plex" feature on the Galaxy S26?

The "Hey Plex" feature was a voice-activation command that allowed users to summon the Perplexity AI assistant hands-free, similar to how one uses "Hey Google" or "Hi Bixby."

Which Galaxy S26 models are affected by this change?

The removal of the feature has been observed across the entire Galaxy S26 lineup, including the standard S26, the S26 Plus, and the S26 Ultra.

Can I still use Perplexity on my Samsung phone?

Yes, the Perplexity app is still functional. You can open it manually and use its features, but you can no longer trigger it using the "Hey Plex" voice command after the latest update.

Why did Samsung remove the voice detection for Perplexity?

Neither Samsung nor Perplexity has provided an official reason for the removal. It could be due to a software conflict, a decision to streamline assistant options, or an update from the app developer.

Will the "Hey Plex" feature return in the future?

It is currently unknown if the feature will be reinstated. We are waiting for an official response from Samsung regarding whether this change is permanent or a temporary bug.

🔎 The removal of the "Hey Plex" feature marks a curious turn for the Galaxy S26 series, which was marketed heavily on its flexible AI ecosystem. While Bixby and Gemini remain capable assistants, the loss of a third-party voice trigger limits user choice and customization. As AI continues to evolve on mobile platforms, it will be interesting to see if Samsung restores this functionality or if the push toward a more consolidated assistant experience becomes the new standard for the brand.
