Same here. 
Plain typescript starter tabs gives a WSOD on the Moto G device with Android 5. Just like my own project.
BUT the actual conference app DOESN’t have this problem. Runs fine on the Moto
So there must be a difference between these two…
Perhaps it’s a general nav issue, like here: White screen on TABS starter
But all apps are running fine in my emulators, using beta.4.
@mhartington can you please check this on a real Android device?
