I’m also interested in this foldable phone, but it’s said you must pay much higher price than Huawei official price to get the second hand units(the 2 hand mate X is new original, unused and box-unopened).
Many buyers in China buying this huawei Mate X 5G phone just aim to re-sell it at a higher price so as to earn some money. The key problem is Huawei provides very very limited qty to sell online every Tuesday and Thursday on Huawei mall.
