The Galaxy S5 came out in 2014. I got mine new from PureTalk for $200. Unfortunately they only had a few of them. That was about 5 or 6 months ago.
When I got it the battery was dead. It had probably been sitting in a warehouse somewhere. It charged up just fine but by that time I'd already bought a new battery. It's been a good phone.
Replacing the battery, which I rarely have to do, takes less time than the phone needs to start up again. Maybe 10 or 15 seconds.
It came with Android 5 but within half an hour of turning it on it updated to Android 6 something. I forget the exact version number.
Samsung makes their phones more difficult to use than plain vanilla Android but it's not bad and it does everything and it's very fast. This was the fastest Android phone on the market till the Galaxy S6 came out. I don't play many games with it but I have a few times and it's good.
I'd rather have this than a Galaxy S6 because that lacks an easily replaceable battery and doesn't have expandable storage. I have a 128 gig card in mine, although I'm not really sure why.
The manager of my retirement home has an Iphone 6, or 6s, I forget which. She's always trying to figure out how to do things that mine does easily, such as watching videos converted from a DVD. She's been watching how easily I do things like and she's swearing her next phone will be Android.
By the way I think I've figure out the secret of the Iphone's success. When you use it it emits an addictive chemical that turns you into mindless zombies who wander around with their arms sticking out in front of them muttering "Iphone, Iphone".
