We have Flurry and GA running on both Android and iOS apps. However, seeing 30% more sessions on Flurry than on GA for the same period of time.
Has anyone experienced this as well? Ideally don't want to run both.

In Flurry, you notify the Flurry SDK every time one activity starts/stop. If once the activity has been stopped, it is not started in more than 10 seconds, Flurry considers the new interaction as a new session. http://support.flurry.com/index.php?title=Analytics/FAQ
In Google Analytics that time threshold seems to be 30 minutes. https://support.google.com/analytics/answer/2731565?hl=en
This could explain the different number of sessions reported.
At the en of the day, what is a session in Android? Such concept does not exist. Analytics SDKs need to define the concept somehow, and if they use different criteria you will get different numbers.

Agreed! The sessions at Google Analytics are 30 min by default, but you can manually change them to shorter sessions if you haven't. I would match the length of time on each session and then compare data after that. Good luck!
