    Could you share some more information? For example, a demo project could reproduce this issue.

    @REJAH - Are you using HockeyApp, MobileCenter etc.?

    I've had a quick play with this today, and have seen the same thing when starting an app on Android. Shows the splash screen and then hangs. Unfortunately, it hasn't done it when using the debugger, and it doesn't happen every time. Unfortunately, I'm out of time today and probably won't be able to look at this again for another week.

    My suspicion, and that's all it is, is that some interaction with another component (I'm thinking HockeyApp, but could be wrong) results in a deadlock, livelock, or simply a race condition when the device's date/time is moved into the past. As we have just changed from summer time to winter time (a change of daylight saving time), I wonder if it might somehow relate to that - possibly a local time to/from UTC conversion problem. That's just a suspicion - if I had time, that's where I'd start investigating.

    A few version numbers for reference: Xamarin.Forms version="" Xamarin.Android.Support.* version="" HockeySDK.Xamarin version="5.1.2" Microsoft.Azure.Mobile.Client version="4.0.2"
