Ok, no fake. But your Android version is strange: 4.2.1, HongMi is on 4.2.2.
Looks like you have a ported Developer ROM from another device installed.
Did you install this or was it installed when you bought it?
Check this thread carefully

It was allready installed (with root ) from merimobiles when I bought it.
Later today I will try the SP flash tool.
Thank you.
