How are you securing the PIN entry? It looks like that happens on the same screen as the random 3rd-party apps get to run on, leaving open the potential for an app to intercept the PIN. As i understand the PCI stuff, anything that the PIN hits is fully in-scope.

We designed a solution to keep the switching logic between standard touch and PIN entry within PCI scope such that PIN entry is not even visible at the lowest levels of Android (and thus 3rd-party apps). Also, 3rd parties do not get to run on or take control of that screen.
The same question here. Anyone can develop and 3rd-party app to capture the PIN on the same screen from the payment app.

A rogue app asking for PIN on the merchant facing screen ? not sure there's anything much we can do about that other than making sure we catch that during the review process. Whenever there is a need for the consumer PIN entry, it's driven by the second payment processor - not from the android side.

Should be able to prevent PIN information from getting accepted by any means other than your locked-down PIN entry screen. So, any app that wants to grab people's PIN entry would either require them to enter their PIN twice, or block the transaction from going through, which should be very visible.
