comment Does Android encryption really prevent law enforcement access?
Google still seems to be able to remotely unlock a device even when using a PIN or password as of Android 4.4. On the Android Device Manager, the existing screen lock mechanism can be replaced with a password entered in the web interface. I haven't checked what happens in case the device is encrypted, though (since this would theoretically bring the lock screen password and the encryption password out of sync).

comment Is building an NFC payment app without a secure element like Apple Pay fundamentally insecure?
Based on the content of your question, do you actually mean something like "is creating an NFC payment app using HCE, i.e. without a secure element, inherently insecure"? Apple Pay is only one of various mobile payment systems that use a secure element.
