HTC Desire 10 Pro specs leaked by GFXBench?
The phone is powered by the Snapdragon 820 SoC with a quad-core 2.1 CPU and the Adreno 530 GPU. 4GB of RAM is inside along with 32GB of native storage. A 12MP camera adorns the back of the unit with a 5MP front-facing camera handling selfies and video chats. Android 6.0.1 is pre-installed.
Besides the HTC Desire 10 Pro, you might have briefly considered this to be the Nexus Marlin. But the size of the screen, and the use of Android 6.0.1 instead of Android 7.0 quickly puts the kibosh on that thought. So we will go with the Desire 10 Pro for now. The phone, and its lower-end sibling, are both expected to be released next month.
