The U12 is almost guaranteed to come with the Snapdragon 845 chipset under the hood. The smartphone found itself on a list of devices allegedly powered by Qualcomm’s lagship processor, leaked by a Weibo user. The list also contains flagships like the Galaxy S9, LG G7, and Google Pixel 3.
The HTC U11 launched with 4 and 6 GB of RAM, paired with 64 and 128 GB of storage respectively. Things likely won’t be much different with its successor, though HTC could kill the 4 GB model and only offer 6 GB of RAM, as well as provide a 256 GB storage variant.

The U11 and U11 Plus have a single shooter on the back. A dual-camera setup has almost become a new standard for flagships, so we expect to see it on the upcoming U12, with the latest rumors pointing toward a dual main camera with 12 MP and 16 MP sensors.

HTC has to innovate in the imaging department to keep up with the competition. The Galaxy S9 Plus is believed to have one of the best cameras around and P20 series could include a model with a triple-camera setup.
