Officially, it has no updates after Android 2.3.6 Gingerbread. The ROM is unofficial build and in beta version, but despite this, the ROM is almost stable in major functional categories which include:
- Calls
- Audio
- WiFi
- Bluetooth
- Proximity Sensor
- Compass
- GPS
- USB Mass Storage
- Camera USB/ WiFi Tethering
- USB OTG
- Micro SD ex-Fat support
What else does an Android user wants? Also KitKat does work with hybrid memory allocation and many other new library and drivers. Team managed to make it work on platform which was unexpected.
I hope this will give rise to development on other abandoned devices with almost same specs as Samsung Galaxy S Plus.
