According to @LlabTooFeR leaker, the HTC's U12 will indeed have a 5.99-inch QHD+ screen and will be powered by Qualcomm's latest Snapdragon 845 SoC, backed by 6GB of RAM, just like it was rumored earlier. On the other hand, the leak also adds a couple of other interesting pieces of information including the dual rear camera setup with 16- and 12-megapixel sensors, 8-megapixel front camera, 256GB of internal storage, 3,420mAh, IP68 and Android 8.0 OS, with HTC Sense 10 on top of it.
It also mentions the Edge Sense 2.0, HTC Face Unlock feature, and full Treble support for Android OS.
Surprisingly, the leaker also puts the launch date for sometime in April.
