Median cold-launch time on A13-and-older devices rose from 1.10 s to 1.48 s in build 2.3.0. Sessions that launch slower are 2.1Γ more likely to end on the first screen. Measured on device β no profiling build required.
Cold-launch timing sampled on-device β no profiling build required.
The regression tracks the new onboarding assets loading synchronously at startup.
The sessions this was drawn from β replay any of them.
