Good question.

Imagine a situation like this: You have an Android phone and also an iPhone with almost the same functional performance.

When you want to login to a banking website to do some secure transactions, which phone will you preferably use?

I suppose most people will choose to use iPhone over the Android one.  

If we even are in this case, None is safe though, There are other ways that could be used to "get" "hack" etc etc details or anything. Yes i would even prefer iPhone though, but if my mobile is clean and i'm using it perfectly and keeping checks on my safety i don't see any reason not using it.

I would use neither of the two any where in the world.  Particularly in South Africa there is very high cyber crime rate and these guys have become experts at SIM CARD swapping.  So device doesn't really make a difference.

For those who want to know more about SIM Card Swapping here is a good article about it from Norton Anti-Virus Site:

I think it's one of the highest risk factors in your banking account if you should make your phone number a key to your account.  It's dead easy to get to.  Regardless of which phone you use.

This happened with my friend once there is a online money application called "EasyPaisa" which uses a 4 Digit mPIN and if you forget the mPIN it sends you a OTP. My friend received a call from the official number that we need to do this bla bla bla and he sents his OTP. He lost about 110$. It's still not sure to this day how do they called from the official number, We tried asking the official helpline, I think they might have somehow reversed it.
