This is a good chart to compare differences on IOS and Android:
http://www.diffen.com/difference/Android_vs_iOS
There are many many hardware manufacturers with special features and optimizations for different applications available. So think of this as a generic OS Phone Comparison only.
Just the straight scoop.
Uh, no, It is actually a poor chart as there are many errors on the iOS side, and even some on the Android side, which is to be expected since it is obvious compiled by someone who isn't familiar with iOS and what is possible or available. Here, let me correct a few mis-conceptions, and let me bring it somewhat up-to-date.
