Overview
- After the first Galaxy S26 software update, the Perplexity app’s “Hey Plex detection” option disappeared and the phrase no longer triggers the assistant.
- Perplexity CEO Aravind Srinivas confirmed the removal is temporary while Samsung and Perplexity switch the wake word to “Hey Perplexity.”
- Voice activation on affected phones now works for only two assistants, Bixby and Google’s Gemini, until Perplexity’s hotword is restored.
- Neither company has provided a reason or a timeline for when the updated wake word will be available.
- It remains unclear whether the change was delivered through the system update or an app update, though SamMobile believes the system update is the likely source.
