I live in India and have bought my Note 2 from Oman in November 2012. Recently, I have been getting too many reminders from Samsung to update my firmware. I am scared that if I download and update the software my phone may crash and since the warranty is covered only in Oman, I will be stranded if something goes wrong. Are my fears unfounded? Should I go ahead and get the updates installed? What are the benefits of updating the software? Do I get additional features?
