The release comes jointly from XDA member king1990 and the ArrowOS team. Features like Bluetooth, RIL, audio/video playback, and Wi-Fi are seemingly working. But given that this ROM is still in its nascent stages, users may experience a few bugs. The release notes claim that features like Wi-Fi Casting and device encryption are non-functional. Further, due to compatibility issues between AOSP and Samsung’s 4G LTE services, Wi-Fi calling and VoLTE are reportedly not working either.
The custom ROM will only work with some variants of the Galaxy S9 and the Galaxy Note 9
Another crucial caveat for this custom ROM is that it only supports the Galaxy S9 and Note 9 variants featuring the Exynos 9810 SoC. This, in turn, means that models running the Snapdragon 845 chipset are incompatible with this new ArrowOS custom ROM. But if you do have the suitable device for this ROM, you will be treated to a stock Android experience. Among the new features include all-new widgets and the newly introduced Privacy Dashboard. While the current release of the custom ROM is far from perfect, future iterations will likely fix some of the bugs. We came across an Android 12-based custom ROM for the Samsung Galaxy S III earlier today. That’s undoubtedly a bigger feat, given that it is almost a decade old. If you own any Samsung flagship from the past couple of years, it’s likely that it has already received the Android 12 update with One UI 4. A recently leaked roadmap indicates that the company’s Android 12 update rollout could carry on until at least July this year. Some devices could make the jump directly to One UI 4.1, which will be revealed with the Galaxy S22 next month.
