Huawei applies for “4D Touch” trademark

If the phrase “4D Touch” sounds strangely familiar, it's probably because it reminds you of 3D Touch, Apple's pressure-sensitive screen technology that debuted with the iPhone 6s. What's 4D Touch, though? Right now, we have no idea, but we do know that it's some sort of technology or feature that's under development at Huawei. The manufacturer has applied to register a trademark called “Huawei 4D Touch”; sadly, not much is known beyond the name itself.
