Corvus OS Android 12 GSI (Generic System Image) Download + Review

Known populars as a ‘Gaming ROM’, Corvus OS became one of top project amongst custom ROMs in the Android community. Now you too, can try it on your Project Treble-supported Android devices with the GSI build!

---

Nerdizen.xyz — Unlike AncientOS Android 12L GSI I have posted before, Corvus OS is a ROM that is focused more towards features rather than massive Android UI overhauling. People also seems synomized the word of “gaming” and Corvus OS.

Maybe it’s because Corvus OS has features that enrich gaming experience on Android device and help Android gamers with plenty features on gaming activity, or it has performance tweak in mind over customization features? It came back to each other as how we use an Android device is different from person to person.

Quick Review of Corvus OS Android 12L GSI by Tipz Team Builds

Note: The one I have tested running well on my ASUS ZenFone Live L2 Android phone is the older version v. S3.2. I haven’t tested the newer version v. S4.0 so far.

From videos or on social medias, I saw many people said and relates Corvus OS as a gaming ROM. Perhaps, people judge it by features that prebuilt that ease the android gamers, or the ROM is build by prioritizing performance? Perhaps the earlier is closer to why Corvus OS is synomized with ‘gaming’, because they even have special section in the customization features called “Gaming Space”.

But me personally, I rarely play games on my Android phones these days so the only thing I can say about Corvus OS is it is one of well crafted ROM built with many features and some little sweet modifications to the core AOSP system UI.

Bugs

Note that this Corvus OS is GSI, every devices may have less or more bugs depends on device models.
