The Samsung Galaxy S2 Android 4.1.2, JellyBean update leaked at the end of last week in the form of a new ROM.
This new firmware appeared for installation in XDA-Dev threads and packs some of the latest features now available to those using the official build of JellyBean.
The official firmware is currently in test mode and its build number is I9100XXLSJ. It is expected to be rolled out in the very near future. This new leaked version is said to be pretty close to Samsung's when it finally is released for the Galaxy S2.
The leaked firmware's features include TouchWiz with Direct Call, AllShare Play, notification bar enhancements, S-Cloud, Pop Up Play and Google Now.
There is still no word on whether or not the multi-window mode will be available on the Galaxy S2 when it receives the JellyBean update.
In other Samsung news, the Galaxy S4 specs could include a 1080p 4.99-inch Super AMOLED display.
Samsung is expected to unveil these new screens at the Consumer Electronics Show set to take place in the beginning of next year.
The company has already begun producing these new displays that have a resolution of 1920 x 1080 with a pixel density of more than 441ppi. This is twice as many pixels as Apple's Retina display found on the iPhone.
Another Samsung Galaxy S4 specs leak revealed that the new device will feature a 13-megapixel camera.
This information derived from a document that surfaced on the internet this week.
A higher amount of megapixels will make it more challenging for Samsung to have the handset perform well in low light conditions, since pixels get smaller and noise gets in easier in those conditions.
This 13-megapixel sensor was originally planned for the Galaxy S3 and second-generation Galaxy Note, but when the time came to release the two devices, Samsung chose to stick with an 8-megapixel sensor for efficiency.
A 13-megapixel shooter would be capable of capturing images with 4208 x 3120 resolution. This camera would require more processing power and extra RAM if Samsung were to include it on the fourth-generation Galaxy S.
