Android large empty storage marked as full (new phone) So I purchased this brand new X27 Plus with 64Gb storage, the phone shows 63Gb of free space when checking but I keep getting "your storage is full" errors.

When I plug it as MTP on my computer it actually shows the 64Gb disk as used space while it's empty. When I plug it as USB storage, it divides it as a full 1.25Go G: disk and an unreachable H: disk. I tried to access it with "DIR/A h:-s" and get "the device is not ready".

Any ideas of what's going on and how to get this working ?
Do not unlock the bootloader because you will lose warranty.
Check the following command to proof it's a fake X27 plus or install this app  

adb shell cat /proc/partitions
