Samsung has confirmed that Galaxy S III will get Jelly Bean update. Unfortunately, its predecessor, Galaxy S II I9100/I9100G won’t be update, to Jelly Bean.
The reason why Samsung won’t update Galaxy S II is because hardware limitations, including:
- The screen resolution is too low. It only has WVGA resolution (480 x 800 pixels). The recommended resolution is 720 x 1280 pixels.
- The processor only has two cores. A quad-core processor is recommended.
- Jelly Bean flavored with TouchWiz UI won’t run smoothly on the phone.
So, Samsung Galaxy S II phones will remain on Android 4.0 Ice Cream Sandwich unless you use custom ROM with Jelly Bean OS. The same thing happened on first Galaxy S, which won’t get ICS update because of hardware limitations too.
