Few weeks ago, sources revealed that Galaxy S3 and Note 2 won’t be upgraded to Android 4.2.2. Instead, Samsung is straight away going to release Android 4.3 update for these devices. But it will take some more time for them to build this update. Since building process involves lots of testing, we might expect Samsung to roll out Android 4.3 update somewhere in the Q4 of this year (say in between September & October). Being a high end device, this might feel embarrassing for Note 2 owners. But on the other hand, they’ll be getting a direct upgrade to latest Android 4.3. So, that much delay is worth waiting for an official update to come out (especially for Android 4.3).
Though Android 4.3 is a little update over previous Android 4.2.2, it includes some of the captivating features such as virtual surround sound, permission manager, enhanced dial pad, Location detection through Wi-Fi, faster user switching, enhanced photo dream, additional international language support etc. Some of the hardware related features are: improved Linux kernel, Bluetooth Smart support etc. Sounds interesting, doesn’t it? But as I mentioned earlier, you’ll be seeing these features (or the whole update) after the span of some months.
But why one should wait for an official update to show up? Being an open source OS, Android source code can be compiled by anyone i.e. developers can make their own custom OS (by compiling original source) based on this code. Compilation and porting of original Android source code is often called as AOSP ROM (Android Open Source Project). But the result of an OS made by tweaking the same by our own way is called a Custom ROM. Currently, there are many custom ROMs available for huge number of Android devices but some of them are quite famous. The list includes- Cyanogenmod, AOKP, ParanoidAndroid, RootBox, LiquidSmooth, Carbon etc.
Currently, only Cyanogenmod has built a ROM based on Android 4.3, known as Cyanogenmod 10.2 (in short CM10.2). Courtsey to XDA Recognized Developer pulser_g2. CM 10.2 offers lots of new features over stock Android. This includes- pre-rooted firmware, new theme engine, focal camera, CM’s own customization settings etc. As of now, CM 10.2 is in experimental phase i.e. you may experience some bugs after installation of the same. But no worries! As developers are working hard on this project, those bugs will be fixed soon in the upcoming updates.
