I like to use Android because of I prefer to use Android for Bitcoin transaction

I think both of them in transactions are totally same in everything.. They way use Bitcoin and speed transfers are same
So what's makes different from them then?

Android since this is my preferred platform and the majority of the phones are vastly superior in features.

i feel like android has smoother bitcoin transactions but i personally prefer ios just because thats the phone i own lol. I hope more apps come out for ios similar to what mycelium for android. that would make ios a even more bitcoin friendly platform.

The idea of storing a larger amount of btc on my phone scares me. So i've only used the android app to test out an ATM machine once.

i think both is same,android and ios have same good for bitcoin transaction,maybe it depending the smartphone specification,but i more like Android for bitcoin transaction,and has been two years use android for bitcoin transaction.

Not a fan of it for multiple reasons, first phones are rarely as secure as PC's and many people tend to forget it's like a PC for being vulnerable for hacking, secondly it is rarely as private as PC since you actually link all your phone data to your BTC, also it requires trust in an intermediate host than typical no centeral authority BTC clients.

There is plenty of choice on Android if one wants to use bitcoin and go for transactions. I personally use Mycelium which I find very handy, simple and secure. But I saw also Copay which seems the easiest BTC wallet ever created so far.
As of now I'll stick to Mycelium.

I like using mobile phones to make transactions because it has a camera to grab are codes. I do think mobiles are more vulnerable to hacks.
