The folks of Mobilegeeks went in depth with this story and tried to figure out if it’s real or not. The result of the investigation is mind blowing: HP Slate 7 VoiceTab Ultra is the MediaPad X1, the Slate 8 Plus is the MediaPad M1 and the Slate 10 Plus is the MediaPad 10 Link+. One of the ways to figure out which is which is for example the visual resemblance between HP Slate 7 VoiceTab Ultra and the Huawei MediaPad X1.
They also have identical specs, including a 7 inch IPS display with a 1920 x 1200 pixel resolution. Both models rely on the Kirin 910 Hisilicon CPU, a quad core Cortex A9 1.6 GHz chip and 2 GB of RAM. Even the 13 MP camera is the same. Same goes for HP Slate 8 Plus and the Slate 10 Plus, who share the specs of the Huawei models mentioned above.
