Speaking of the “sweet phone” in the smartphone industry, many people would think of the HTC HD2 without ROM and flashing, but in fact, Samsung Galaxy S III also has many supporters, who have been silently continuing to develop this flagship released in May 2012. Let its lifespan be extended continuously. After making the Galaxy S III support dual-boot Sailfish OS and support Linux, some developers even upgraded this phone to Android 12.
The developer of the discussion forum XDA-Developers “html6405” released his development results a few days ago. He successfully launched Android 12 on the Galaxy S III 3G (model I9300) using Exynos 4412 processor, with data connection, camera, and Wi-Fi. , Bluetooth, hardware and software accelerated video playback can all work normally. The Android 12 used by “html0645” comes from the unofficial LineageOS 19.0 custom ROM, but most of the exclusive functions of LineageOS have not been added, after all, this is just the result of the initial development.
This kind of single-person development projects will inevitably have some bugs. Currently, the SIM card PIN code cannot work normally, formatting the microSD will cause constant restarts, and the NFC function is temporarily disabled. All of the above are to be solved by “html0645”. . If you have a qualified Galaxy S III and are interested in upgrading it, you can go to the XDA-Developers discussion area to have a look.
