CyanogenMod 10 port brings Jelly Bean to LG Optimus S

The LG Optimus S has received an unofficial upgrade to Android 4.1.1 Jelly Bean via a direct CyanogenMod 10 port. Even though it may be a work-in-progress build, this is definitely good news for those who want to tinker and tweak around with their old but functional Optimus S. This 4.1.1 port brings quite a few working bits while some are still untested or not working. The calling functionality of the phone, including the microphone, has been tested and is working. Sending and receiving SMSs is working as well. Connectivity options including 3G data and Wi-Fi are working, along with GPS support. The couple of sensors on board, accelerometer and proximity sensor have been tested to work and also the graphics acceleration for the user interface. 


Unfortunately, the sound works through the phone speaker, but it doesn’t work through headphones. Bluetooth has been untested yet, it switches on though. Camera, MMS and Google Now aren’t working at the moment.

It is important to note that this ROM is available and is meant only for the LG Optimus S and will be usable on the ZVG baseband/ radio. This is a direct port and not a source build. It’s good to see that though phone manufacturers choose to ignore older handsets, they still chug along for a few more years thanks to support of communities.
