I have a Xamarin.Forms 184.108.40.20674 in witch I have a TabbedPage inside a MasterDetailPage.
The TabbedPage have multiple tabs (child pages) and works correctly on WP.
However on Android only the last added page (tab) is showed.
Follows a sample to examplify the bug:
Notice that on Windows Phone the app show 3 tab while in Android it only show 1 (the last added).
I have checked this issue and with the help of attached sample I am able to reproduce this issue.

We'd be happy to help you resolve this issue.I have tried a smaller sample and i m not being able to reproduce the problem.
Can you please check the sample i attached, and see if this is similar to what you are trying to achieve. So we can figure out the smaller reproduction possible for the issue.
Xamarin Forms Team
Hello Rui Marinho,
Your sample is actually working, but it is very diffent from the sample (a proof of concept I'm developing).
Since my sample render correctly on Windows Phone (with 3 tabs) but not on Android and iOS (which on shows the last added tab) I'm really sure it is a kind of bug with Xamarin.Forms. Authogh I'm didn't find out where exactly the bug is in my sample. I think the Xamarin team could help find that and if confimed fix the issue on Xamarin Forms.
I think that if it was not a bug on Xamarin.Forms, my sample should be behaving as the same on the three platforms.
I'm really sorry Rui,
It was my fault, since I'm using Autofac to use DI and conditionaly registered my tabPages as single instance for Android and iOS it was generating only on instance of my tab page.
Sorry for the inconvenience and thanks a lot for you attention.
