    Crash-free regression on Android TV, app 3.4.1 - PlaybackSurface.onSurfaceDestroyed

    Acknowledged at 14h. SimpleStream asked for the symbolised stack, which was in the original bundle.

Description

Crash-free sessions on Android TV fell 0.59pp within 36 hours of the 3.4.1 rollout, against a stable 30-day baseline. Crashlytics attributes 71% of the new crashes to one signature in the playback surface. The novelty detector flagged this signature as previously unseen. Retention consequence is already measurable: D7 for users who crashed at least once is 22.4pp below the cohort baseline.

Suggested action

Hold the 3.4.1 Android TV rollout at its current share and request the symbolised stack for signature PlaybackSurface.onSurfaceDestroyed.
