5G phone with a physical keyboard

I love to have a 5G phone with a physical keyboard like the Astro Slide 5G but the screen size turns me down . I wish some body will create/invent a 15.6 inches "360 degrees foldable" "Touchscreen" "Auto-rotate" 5G Cellular Laptop (regardless of the Operating System being used , regardless whether it is INTEL-based or ARM -based) with telephone/phone functionality , so that we can use it as a 5G Laptop , so that we can use as a 5G Tablet ( due to it's foldable design it can be turn into a 5G Cellular Tablet ) , and BEST OF ALL , so that we can use it as a 5G smartphone ( can make telephone calls to any landline telephone/number and reply telephone calls from any landline telephone/number. This is a true and a real Laptop/Tablet/Smartphone(ALL-in-ONE) machine which I have been advocating for several years now . Perhaps PLANET COMPUTERS or any hardware/software manufacturer out there should take a closer look on this kind of machine , perhaps , it could benefit mankind .
