[Nullard]

Hi!
I have a clon Samsung note3 SM-N900 ; build number : JSS15J.N900ZCUBM15
I show you what is written on my device info
device name : galaxy note 3 SM-N900
android version : 4.4.2
kernel: 3.4.0-1590669 se.infra@R0304-14#1 wed Sep 11 23:59:42 KST 2013
Now I would like to verify and
Here is the diagnosis of my device given by various apps of Google play:
TEST SYSTEM '/Tacoty App. / System Info pro / DROID information, all give as result: Samsung SM-N900 Ja3g / processor MT 6572 / DUAL CORE / ANDROID 4.2.2/ 540 X 960 px.
However, ANTUTU Benchmark v.5.6 and CPU-Z give a completely different result for the same device: Samsung SM-N900 / [b]processor MT 6589 / QUADRICORE / ANDROID 4.4.2 (with CPU-Z); ANDROID 4.2.2 (with ANTUTU) / 1080 X on 1920

I need to know exactely the component of my device because it is very important especially if I want to flash which ROM or to upgrader the device.
Thank you to help me.

Mtk droid tools will tell the truth...
Then make a backup of your phone before you flash!
