Google has released the Jelly Bean source code, in addition giving developers an opportunity to port the Android 4.1.1 Jelly Bean to existing devices. Samsung Galaxy Tab 10.1 (Wi-Fi) owners can get their hands on Android 4.1.1 Jelly Bean. An XDA Senior Member MapleSyrup has ported the Android 4.1.1 Jelly Bean on the Galaxy Tab 10.1.
"I've compiled android 4.1.1 for the Galaxy Tab 10.1 Wi-Fi only (GT-P7510, p4wifi)," claims MapleSyrup on xda-developers. "It's really EXPERIMENTAL, only for those curious to see Jelly Bean working," he adds. However, ROM lacks some functionality such as camera, audio, Wi-Fi and keyboard dock. The developer notes that the keyboard dock worked but it was not stable. For more details you can check the official thread at xda-developers.
