谷歌分析ios sdk V2.0短会话持续时间

The app I'm working on is used on an iPad in a retail display. The device has auto-lock turned off, and the app will show a video loop as a type of screensaver after a minute of inactivity. We are using the GA iOS SDK 2.0 beta to track sessions, with a session timeout of 60 seconds. The app starts a session on startup, and also when the screensaver is dismissed by a touch. This is all working fine except for the multiple 0-10 second long sessions we get, with average duration of 0:00. We can start the app, go through a couple of 60 sec. sessions, then get those sessions reported along with 2-3 of the 0-10 sec. sessions. From what I can see the app only starts sessions when it is supposed to, so I'm wondering if this is related to how Google calculates a session. I haven't seen anything in the documentation that explains this and I'm stumped.The app I'm working on is used on an iPad in a
