Sudden drop of session duration

Hi, I'm working in an IT company. Recently, we identified a wired issue in the GA portal. The average session duration of our App drops from 13 minutes to 3 minutes since Feb 15th. The pageview, number of sessions, and unique users doesn't show such a steep drop. We have examined the tracking code, but didn't find any problems. 
 
Is it possible that GA miss some data when processing the traffic?

Hi Zhenzhen,

Did you implement or remove any event tracking on that date? That's because event tracking usually is counted interactively and therefore influences bounce rates and session durations.

Any campaign or other sources variations on that date?
