So i'm looking to trade my iPhone 5 and really wanting a S5 or HTC one m8 but still have a few months before I can upgrade. So i've been looking to swap and have found a few people that want to trade their S4 for a iPhone. Is the S4 still good phone? Its over a year old and i'm not to sure on Samsung and them keeping their phones updated. I'll probably end up getting something when my upgrade becomes available but i'm just tired of iOS and want to try something else for a little while.
