Forerunner X1 is a 5G smartphone from China Mobile with a 6.47" AMOLED screen. The whole device has been rendered more compact through a stacking design. The double-sided curved glass around the fuselage is very round and smooth, while on the back two-thirds of the surface has a matte glass finish while the other one-third is polished. This gives the phone a uniquely rich design character, while also making the phone easier to grip.
