I found an online site "whatismyandroidversion.com" which has identified 9 Pie as the operating system. Since this is an independent site it leaves me even more confused.
That's only going by what the browser tells it, via the Browser ID String. Which I suspect has been doctored as well. Suggest you try one of the diagnostic info apps I posted, like CPU-Z.
It's really what's in the YT video review
@Hadron posted, that I saw what this thing really is. Specifically the Settings screen, which looked very spartan for Android 9, but is typical for Android 4.x.
Then there's this....
Apparently the Android security patch level is two years before Android 9 even came out?
The Baseband identifier string corresponds to the
discontinued Mediatek MT6580 SoC. See my previous comments about Xgody using old or recycled parts.
Also the 3.10 Kernel version, which is from 2013 and was used in Android 4.x.
Of course that's in addition to having the stock Android 4.x icon set, I've already mentioned.
If it looks like a lemon, smells like a lemon, tastes like a lemon, then it very likely is a lemon.
I didn't buy from Wish or Ali Express and I have heard of Xgody. I would be fascinated to know how you could tell what OS my phone was running from the rather scanty information I have posted
I'm familiar with Xgody in China, theirs any many other cheapo products are usually sold by street sellers and night markets around here, along with the counterfeit iPhones and knock-off Gucci bags, etc.

The Xgody in the video was bought from Wish. Whereas the mainstream brands like Samsung, Huawei, Xiaomi, Sony, Apple, etc, are sold in reputable brick'n'mortar stores, or online directly from the manufacturer.
