Don't Update A51 into UI 4.1

[MrDragone]

In Knox Features TIMA getting disabled via software by Samsung on A51 

Why??

TIMA :-

TIMA or TrustZone Integrity Measurement Architecture incorporates privacy and security functions at the embedded systems level, which acts as buffer between the Android OS Kernel and mobile processor hardware.

What a disgusting things of Samsung. 

Before Update TIMA was 4.1.0

After Update No TIMA

TIMA is a hardware integrated into the chip/motherboard.....so they can't "remove" it bro....

Probably One Ui 4.1 doesn't show that in software information....

Even A52 doesn't show TIMA😀😀

Its hidden, not removed. No One UI 4 device shows TIMA version under Knox.

Thanks for this information. But is Samsung gave any official notification for this? coz it's very crucial system of our device we are making pay extra for it.

You cannot remove a piece of hardware via a software update. And why would Samsung disable a piece of hardware in their devices? You paid for it, true, but they paid to manufacture it too, didn't they? Even S22, S21 and S20 series don't have it shown under Knox settings. Doesn't mean they have disabled it in their flagship devices. Also, I don't think that an official notice is needed for such a small change.

Update: TIMA is no longer supported after Android 12 because its keystore has been updated with Google's keystore2. The hardware will use Google's keystore2 drivers.
