Responding to a question on how has implemented security and encryption for fingerprints read by Nexus Imprint, the team said, "fingerprint features are securely encrypted on the device, and processed in the secure Trustzone protected area of memory." The team also said that Android 6.0 Marshmallow fingerprint APIs deny apps access to the fingerprint material. The team also revealed that the USB Type-C port implemented on the two Nexus smartphones only supports the USB 2.0 specification. "So, ease of plugging in + fast charging + optimizing for thinness made us double down on Type-C instead of wireless." Furthermore, implementation of wireless charging also added to the thickness of the smartphones. Both phones feature fast charging technology in any case, the team added. The Nexus team said it had decided to ditch Qi Wireless charging support in the Nexus 5X and Nexus 6P because the handsets now support USB Type-C, which is more convenient due to being reversible. Starting with the handset names, the team said that the 'X' in the Nexus 5X represents the core of the NeXus brand, and the 'P' in Nexus 6P means 'Premium'. They also talked about how the team worked on the design of the handsets and how they felt when they came across numerous leaks and rumours. The group consisting of Hiroshi Lockheimer, David Burke, Krishna Kumar, and Sandeep Waraich answered questions related to the new Nexus handsets, including queries about the the new fingerprint security, the missing wireless charging feature, and the Nexus 6P camera bump. A Google Nexus team on Wednesday held a Reddit Ask Me Anything (AMA) session following the launch of the new Nexus smartphones.
