If you are a fan of the popular custom ROMs available for various Android devices, here is good news. The Android Open Source Project (AOSP) team has started rolling out its latest work, CyanogenMod 10.1, based on Android 4.2.1 Jelly Bean (Build: JOP40D), for a bunch of Samsung devices, including Galaxy Note 2 (N7100) and the major U.S. variants of Galaxy S3.

The users must note that Samsung Galaxy Note 2 in question is the international version of the device with the model number N7100. Therefore, Galaxy Note 2 N7105 or the LTE-enabled Note 2 is not included.

The CyanogenMod 10.1 updates are in the nightlies stage now. Nightlies are daily releases that have the latest patches and developments included, Android Authority has reported.

“Unless you read the change logs, you really can’t tell what will work and what won’t in the next release,” said the report. “However, if these are official, it’s safe to assume that most of the big things like calling, texts, data, etc should work pretty well.”

As Sammobile pointed out, “CyanogenMod is a free, community built, aftermarket firmware distribution of Android 4.2 (JB), which is designed to increase performance and reliability over stock Android for your device.”

CyanogenMod offers features and options that are not found in the official firmware distributed by vendors of the supported devices. According to reports, as of Aug. 24, 2012, CyanogenMod had recorded over 3.1 million installs on a multitude of devices.
