Which smartphone suits me well?

[Anwar]

Guys I really, really need help with this. I'm new to Yahoo and I hope to get answered.
I'm 14, I need a good smartphone that suits me well. Note that I don't have a lot of money, the only two good smartphones I like that are not expensive with good qualities are iPhone 4s and Galaxy Grand Duos (I specified to help you know how much money I have).
I need it for gaming (Racing, surfing etc), and I need it for browsing the internet which helps me with studying, I also need it for apps such as Facebook, Twitter and photo editing apps.
I've had an iPod touch 4g and I loved it, it had amazing apps and everything suited me great. Well, maybe I need a faster smartphone but whatever.
Oh and one last thing, I want it to stay with me for a long time and not get old (which is one of the reasons I don't want to buy the iPhone 4s). I want to keep using it for like 3-4 years.
So, which smartphone should I get? iPhone 4s, Galaxy Grand Duos or other (specify)?
Thanks in advance!

If I buy the iPhone 4s, will it get all the updates the next two years? (iOS updates and new games).

You're asking for a lot since you're not willing to shell out the money. A fast smartphone for gaming AND internet AND social media that's cheap but won't get old in 3-4 years? That's impossible, sorry. Even high-end phones like the iPhone 5S and Galaxy S4 will be old in a couple of years. Heck, the 4S came out two years ago, and you already think that it's outdated.

I recommend saving up. If you can save up to about $100, then you can get an iPhone 5c on-contract. If you're not willing to do that, then you're pretty sunk. Sorry.

Since you say you use your phone for playing games, I would say get the iPhone 4s since it's app store has a better game selection than the play store. Either way, both phones will be old and slow within 3 to 4 years.

Galaxy Grand duos is cheaper . But do not get the Galaxy Grand duos because it's not as good as good as the iphone 4s. If you are planning to get the Galaxy grand duos then just get the s4 or the HTC one.I recommend iphone 4s because it's almost the same as iphone 5s. I am not saying that there's no difference. But not a huge difference between those two. Iphone 5s is basically a minor update from Iphone 4s. Since Iphone 4s has ios7 I am sure it will last another 2-3 years. And i am sorry, unfortunately nothing will last forever. Things will get older eventually. IMO I think you should just save up and get a better phone.
