Do the Nexus 5X or 6P finally have hardware encryption support ?
I didn't notice any mention of those, specially because they failed miserably last year parading full disk encryption on Nexus 6 and got bitten when reviews showed the performance degradation and lack of hardware encryption.
It's a good question, I've looked and the Qualcomm Snapdragon 810 has the support needed, but I don't know if it'll be enabled by default or not in Android 6.
If it's not, then Google are starting to take the piss..
Android 5 has full disk encryption but was disabled by default on the Nexus 5 (and most other phones) due to performance issues.
