How to Update Samsung S2 to Android 4.2.2 Jelly Bean OS
As Samsung doesn't specifically mention the Galaxy S2 as a device that will receive Android 4.2 Jelly bean, but the response can be taken as the only piece of official acknowledgement from Samsung that the Galaxy S2 hasn't been forgotten to update this device.
The Samsung Galaxy S2 was originally slated to receive Android 4.2.2 Jelly Bean until insiders and carriers both confirmed Samsung was dropping the project around halfway through 2013. The reason why is still unclear, although whispers indicate that it could have had to do with problems porting over new Touch Wiz features to the older phone. Whatever the case, once Samsung announced in September that it would be scrapping Android 4.2.2 for phones like the Galaxy S3 and Galaxy Note 2 and instead focusing on Android 4.3 for those devices.
