Nobody got to update to Marshmallow, most silly as it announced 3months ago universally. This is sammy fly brained attitude. Google has made it mandatory himself to update as when it does toto its nexus devices. Android 66 was updated in October 15. Shame on Samsung. Remember India is the second largest country using Samsung product.
Thats what you do not want your customers to be satisfied. NOT going to prefer this phone to anyone. Just a useless phone and money wasting too.
