Huawei first unveiled the Mate X foldable smartphone in February last year but it wasn’t until September that the device was launched. The device was only made available in limited quantity due to mass production challenges. The tech giant is readying a successor to the Mate and may have just filed a patent for the device. 
The patent was filed with the European Union Intellectual Property Office (EUIPO) for a new foldable smartphone. The description and schematics show that the device will come with Stylus support. The patent describes a form factor similar to the first-gen Mate X, but there are some differences.

The most spectacular difference is that the patented phone utilises an inward-fold design while the Mate X folds outwards. Another interesting aspect is the camera setup onboard. The device packs a whopping six-camera setup as against four cameras on the Mate X. Two of the sensors are housed on the front housed on the vertical sidebar, and four at the back.
The sidebar looks different from that of the Mate X. It sports the secondary display and houses the stylus. You can check out the sketches of the device from below.
