The two are not the same.Hey, everyone! The Security Status page doesn't correctly show the Google Play System Update date.
In the pictures, the Security Status page shows: "February 1, 2021". However, the About Phone > All Specs page shows: "2022-02-01".
Or maybe, the Google Play System Update and Android Security Update can have different dates? (Last time I checked, they were the same.)
Security updates are part of the ROM, while Google Play Services update can be pushed by Google, see eg:
Not only does Android get a big yearly firmware update, but there are smaller monthly updates as well. Google Play Security Updates are one such update, and they're different from the monthly security patches. Here's what they do.
On my Mi 9T, MIUI 12.5.2 Stable (last Xiaomi.eu for that phone), the two dates were always different (and in fact, I never got a push from Google to update Google Play Services - it's even two months older than Security update)
PS:I attached also Security Update info from my 11 Lite 5G NE (Lisa), running the stock (not Xiaomi.eu) MIUI 12.5.8, and the dates are different: Security: December, Google Play System: February
