themountofmint Android 5.0, Lollipop, if I remember it correctly (barely anyone I know was using stock/default then, almost everyone was on custom ROMs so it’s difficult to say for sure). CyanogenMod used to have it in 7.1 (Nougat) for sure. Samsung phones haves them in One UI 6.0 (probably before also), so Android 14 (holding one in my hand right now), and so on.
But my previous comment was somewhat weirdly phrased, I get it now after reading it again (typed it in a hurry while waiting for my food to get ready 🤓), my bad; what I meant to say is that Google/AOSP/Android is not copying something from others when that already exist(ed) in Android, for many years at this point.
Example would be - why is there no volume slider in Nothing OS in the control panel/quick settings? But there is once you press any volume button! Why does a Flashlight only work on or off, why can’t you press and hold it to get a slider pop out and get adjustable brightness strength? All those features exist in Android by default, it’s just Nothing choosing to remove them for some reason.
Or this dumb crap - why does WiFi tile only work in 1×1 or 1×2, why can’t it be as Bluetooth tile 1×1, 1×2 or 2×2? (resizable in One UI, Hyper OS, Pixel OS, even iOS which is not Android at all… everywhere but in Nothing OS 🤷♂️)? I mean look at it, lol:

God, do I miss that Windows on Mobile (or whatever the name was, I forgot). It was amazing on Lumias (and 520 is especially dear to me, lovely little phone 🥰), but it failed because everyone was already on Android and iOS so people were lazy to switch to something objectively better back then, meh.
