Grok Bot

Describe the Bug

On Grok Bot iOS, in-app voice transcription (the app’s own composer mic to text - not iOS keyboard dictation, not voice-call) often crashes the whole app mid-transcription.

Before realtime streaming text, this was a simple record then pause/submit flow and I never crashed. After realtime streaming text was added, crashes started. Short takes are hit-or-miss; ~5+ minute takes crash much more often. When it crashes, the in-progress text is gone and I lose my chain of thought.

I still prefer this feature and keep using it a lot. I don’t avoid it - but long takes are stressful now because a crash wipes the thought mid-stream.

I have never seen this kind of crash on ChatGPT’s voice/transcription. I haven’t tested long voice-call enough to comment on that. Device: iPhone 15. No Android to compare.

Starting point for debugging (hypothesis, not proven): the realtime streaming text path may lean on on-device / edge compute and RAM. I am on an iPhone 15 with limited RAM; stronger phones may not hit this as often, which could also explain why reports are sparse. Worth checking memory pressure / on-device ASR or streaming-text allocation first.

Steps to Reproduce

  1. Open Grok Bot on iPhone.
  2. Start in-app voice transcription in the composer.
  3. Speak for a long take (especially ~5+ minutes) while text streams live.
  4. App may crash mid-take; content is lost.

Expected Behavior

In-app voice transcription should not crash the app, and a failed take should not wipe the in-progress text.

Hey @kenwongch,

What you’re describing isn’t intended behavior, and it isn’t caused by anything on your end or by your iPhone 15. It’s an issue we’re tracking with the live text in the in-app mic on iOS.

Until there’s an update, this should help with long takes:

  1. Use the mic on the iOS keyboard instead of the composer mic. It’s a separate path, so it shouldn’t hit this crash.
  2. If you’d rather keep using the in-app mic, shorter takes lower the odds, though they won’t fully prevent it.

I’ll post here when there’s an update.
