Samsung S3, Galaxy Note 2, iPhone 5?

[Winston]

It's obvious that out of those 3 the Note II is better. Has the most features out of the 3. All 3 phones are basically capable of doing the things you want. The camera on all 3 phones are pretty much identical (no really, they use the exact same cameras made by Sony). The S III and Note II is a bit like the Xperia Arc S (since they run the same OS), but it runs on a newer version which makes it a very good experience. But since you're in year 9, I don't think you need such high end phones. But since you insist, Galaxy Note II FTW!

S III Pros:
Large HD Super AMOLED Screen
Runs on Android 4.1.2
Decent specs.
Can add SD card for memory expansion

S III Cons:
Most fragile phone I've ever seen (a case is a must)
Screen has a pentile matrix which kinda makes images look fuzzy when it shouldn't (considering the HD resolution)

Note II Pros:
It's everything that the S III is but better
Better battery
1 version: has 4G
Massive screen (no pentile so quite sharper compared to S III)
Durable
Stylus
Faster

Note II Cons:
Not for me but for you, might be too big

iPhone 5 Pros:
Compact
Fast
Easy to use

iPhone 5 Cons:
Limited
Relies heavily on iTunes
Too basic, can't do a lot
App Store has more paid apps than free apps (compared to Google Play)
