Reportedly, Huawei is preparing to announce a new foldable smartphone next month in China. Due to launch alongside the Watch D, the foldable will have a clamshell form factor like the Galaxy Z Flip3. Huawei's alternative should undercut Samsung's flagship on price, though.

I will wait until 2023 to buy a Huawei phone. China starting to ramp up 14nm. By 2023 mass production of 14nm should be available to Huawei. Combined with Huawei expertise in stacking 3D chips, Huawei phones will make a big comeback in 2023 with 3DSoCs. 14nm chips stacked together will have equal performance to 7nm. Huawei will also produce another 3DSoC equivalent to 5nm for high-end phones and tablets.
