4. Sanyo Zio
Since I’m not a technology nerd, I definitely had to look up this one. Yes, I know about Samsung, Apple, HTC and Sony Ericsson but about Sanyo Zio, I don’t. Well, it turns out that besides its place on a list of most hackable smartphones, this one could end up on a list of smartphones which you will probably never want to buy. It is a midrange Android phone from Sprint. If you read the review from Phone Arena, security will be least of your worries.
