Question [Q] Help with S4 Clone

I bought an unlocked TMobile GSM S4 and it appears to be a clone. I've put down below the information I've observed so far.
I'd like help understanding which source of information would be correct, CPU-Z & Antutu, or the Genuine Galaxy App. And since the OS is halfbaked, is there a stock OS I should be looking for?

Any advice, suggestions, insights would be greatly appreciated!!!

1. OS is very possibly a custom
- Upon hard reset, there are no TMobile apps.
- Samsung app opens into a Korean counterpart store-type app
- Antutu and CPU-Z are pre-installed
- Calendar, FM Radio, and several other apps seem partially complete (empty spaces, tabs don't work)

2. Home screen pages: pages return after a restart (that is after I have already removed several pages and left just home page)

3. IMEI and S/N check out fine on several verification websites (e.g, etc); I can see mfr was Samsung, made in Vietname, production date and

warranty information all present (Could this all check out OK even with a clone?)

4. Antutu and CPU-Z Information (CPU-Z in parentheses if different from Antutu)
- Phone model: GT-i9500 (CPU-Z: GT-I9500 JA3GXX)
- CPU Hardware: Universal5410 (CPU-Z: Samsung Exynos Oct 5410 1.6)

5. Camera showing 13mp, but clicking sound when focusing. Picture quality not better than my Note2

uninstall CPU-z, antutu, reinstall. Look on the results, compare if not changed with previous ones (both apks on clone can be fake).
find service codes for SGS4, check what works on your phone and what results (especially in service menu) you have.

Galaxy S4 has no FM Radio by default, not only this, it's very unlikely it'd come with CPU-Z and Antutu, and the Genuine Galaxy app shows different results from the other 2 apps. Let's see each of them...

Antutu and CPU-Z shows genuine results, now what worries me at most is the Genuine Galaxy app.

Model - Yes, it exists

Device Brand - It's right

CPU HW - SMDK4X12 is a processor found on fake Galaxy S3s

CPU Model - ARMv7 is right, before editing my post I confused it with architecture, the model is right.

CPU Cores - Here is the killing thing, if it showed 4 it could be that the app confused with the big.LITTLE architecture used in Exynos Octa-Core, but as it's showing only 2...

Total RAM - 469MB is supposedly a 500MB device, so it's 4 times less than the real S4

Total ROM - 950MB is supposedly a 1GB device, which is clearly way less than it supposed to be

Screen Resolution - This is the screen resolution of low end devices

Camera - 8MP is not what it should be, the sensor may be another killing point...

It reminds a lot a fake Galaxy S3 (, but it's even lower in specifications, but the site that I just linked could be lying about some parts, so it's very likely you got a fake S3... One thing is certain, it's NOT an original S4, sorry, but you've been scammed.

Can't uninstall cpuz or antutu. There is only a disable option.
As for the service codes, I searched for the codes and this is what I have so far:

Sensors: only Accelerometer Sensor showing up
* #1234#
*#12580*369# to check software and hardware information.
RF CAL: 2013.4.25
HW REV: MP 1.300
*#0228# Battery status (ADC, RSSI reading)
*#32489# Service mode
*2767*4387264636# - show the product code
*#0011# - Service Menu

Seems very likely that it's a fake or clone. And the OS has so many glitches (empty calendar app, s memo etc..)

Thank you for assessment. Surely is a scam. It's there a way to install a better stock like Rom? And wouldn't a reinstall affect the cloned imei? Is installing a Rom on a cloned phone more challenging than a regular phone?
