Install Android 4.2 Jelly Bean on Galaxy Tab 2 10.1 with CyanogenMod 10.1 ROM

Recently, a host of Android devices are getting the latest Jelly Bean update - Android 4.2 - via the popular CyanogenMod 10.1 (CM10.1) custom ROM. Samsung Galaxy Tab 2 10.1 is the latest to taste Android 4.2 Jelly Bean update, with due credit to popular CyanogenMod developer codeworkx.

Galaxy Tab 2 users can now enjoy the latest Jelly Bean features including lockscreen widgets, quick toggles in status bar, multi-user support, 360 degree panorama mode with Photo Sphere, Daydreams screensaver mode while charging, Gesture Typing keyboard for Swype-like typing, and enhanced performance, besides high level of customisation capability.

Users should, however, note that the ROM is still under development and so, may harbour a few untested bugs or broken features. CM10.1 will not include any Samsung-specific features or native apps found on the stock ROMs, as it is an AOSP based release borrowed from the Nexus devices that comes without any bloatware and skins.

Here is the list of recently reported known issues from the developer's website:

    •  P3113/P5113: no IR-Blaster support
    •  The home screen is always in landscape mode
    •  The screen many a times does not respond to touches for unlocking, needed to reboot the tablet.
