Samsung Galaxy Grand, the 5 inch Dual-SIM device has an update. The 60.42 MB update is available over the air and is meant to fix stability issues. So far users in India had previously reported two updates available, one 27.86 Mb for stability improvements and the second one related to blocking mode on the phone. The one I got here was for improved stability.
You will need to do the search for updates to get this if it hasn’t already come via automatic updates. Head on to settings, scroll down to About device, tap on software updates and tap update. The update will work over the air and if it doesn’t you can always use the “beloved” KIES. 
Currently I still have issue with the Galaxy Grand in that it doesn’t have a shortcut at the notifications area to turn off autosync with a tap unlike with other devices, you have to go to settings>accounts and turn it on or off individually for each app. Otherwise I am enjoying the device and the productivity it offers on the 5 inch screen. I like working on smartphones, you know!
