Samsung recently announced that they are committed to delivering Android and Security Updates as much as 3 years which is big news if I may add, but this does come with some negatives as well.
For starters, they are only committing to these 3 years of updates for their flagship devices which are the S, Z, and Note Series Smartphones. Now on one hand I am a little bit happy that at least they have said that they will deliver but on the flip side, it also looks like they don't give that much importance to their other Series Smartphones which is definitely a bummer.

There is also the point that they haven't mentioned the timeframe in which their devices will receive the updates so all of this could mean nothing at all as they push updates at their own pace.
I am also kinda disappointed at Samsung for not grabbing the huge opportunity/void left due to the growing anti china sentiment in India. I believe they could have taken a huge chunk of the market cap if they decided to be a little aggressive in the pricing segment.

Well it is what it is.
