KM version discrepancy

[gavdoc38]

Not entirely sure if this is an issue, but it is a difference against TS original so I'm highlighting it and you can be the judge! 😊

Device is Samsung Galaxy S9+ (SM-G965F) running custom Lineage OS Android 16.

TS original shows Key Master 3.0

TEE-S shows Key Mint 4.0

Well, you shouldn't compare with TirckyStore.

Instead, you should compare with the result when no module is applied to it.

Ah, well I have broken TEE so I can't do that directly. However, as the S9+ launched with Android Oreo (and finished with Android 10), I believe Key Master 3.0 is correct.

Edit there is also this file / contents, suggesting Key Master v3 in vendor partition:

What is the result of

adb shell ls /system/lib64 | grep hardware

on your device?

Ah, so this may be a result of the custom ROM including libraries that wouldn't have been on the stock device? Result is:

I notice there are keymint files above which do not appear in this stock ROM dump from the same device:

Given the result of your system library structure, I think 4.0 is a appropriate version to return.

TS result is not the golden rule, and this version match hasn't caused any trouble yet.

[gavdoc38]

That's perfectly fine. Like I said I wasn't sure if it was an issue because I've not experienced any problems due to it, and I wasn't meaning TS original is always correct; I just thought it worth highlighting the difference so you were aware.

Thanks for looking it over. 😊
