Slow Sessions (games only)

In Android vitals, a slow session is a session in which more than 25% of the frames are slow. A frame is slow if it is not presented less than 50ms after the previous frame (equivalent to 20 FPS). Android vitals also reports a second Slow Sessions metric with a target of 34ms (equivalent to 30 FPS). Using Slow Sessions, you can understand the frame-rate performance of your game, which impacts how smooth and fluid your game feels to users.

In due course, Play will start steering users away from games that cannot achieve 20 FPS on their phones. Note that Android vitals only begins monitoring frame rate after your game has been running for one minute.
