Unlegacy-Android started out as the OMAP4-AOSP Project. It was created in late 2015 in order to maintain a clean and organized place for pure AOSP support for various OMAP4 devices, such as the Galaxy Nexus and the Samsung Galaxy Tab 2 series. Over time this evolved to support more than just these devices, but still maintains its roots of supporting "legacy" devices that no longer receive "official" updates: hence Unlegacy Android was born. In our opinion, these ROMs are how the official updates would look.
On top of AOSP, we only include changes which are necessary to support the hardware, be secure, and get acceptable performance. Current features for hammerhead include:
- BFQ IO scheduler (official kernel 3.4 release), set up so GUI processes have the highest priority
- Last upstream (kernel/msm) hammerhead kernel tag merged
- Enhanced backlight map for lower min brightness
- Night display blue light filter (GLES-based)
- KCAL & PCC color temperature interfaces
- Other security patches & minor bug fixes
- F2FS support from K4.4 backports
- SELinux in Enforcing mode
It's important that /system needs to be unmounted before installing the ROM - some recoveries tend to leave it mounted after performing operations on it.
If you're planning to install GApps, be sure to read the second post.
Aside from these, installation and upgrading is no different than on other ROMs.
- No known issues for hammerhead yet.
See: http://builds.unlegacy-android.org. Our automated builds ensure that we always have the latest Android security patches merged in, without having to manually start and upload builds
Also, we'll have a built-in OTA updater (just like stock) soon (it's a work in progress).
There isn't much to say here - this is AOSP, if you install GApps, you pretty much get the same thing that's running on the Nexus devices (see second post). The aim of this project is to create a fast and stable ROM, as close to AOSP as possible without diminishing usability. Occasionally, small non-AOSP features may be implemented, provided there is a clear need and they make sense on hammerhead.
