I have the Galaxy S5 and really enjoy it. The case I got for it is heavier than the phone itself! It also has expandable memory. I plopped a 32 gig card in there. Battery life is good. Make sure you turn off location, when not in use, as well as Bluetooth.
I have the Galaxy S4 with a 64GB card. My wife has the S5 in the waterproof version. I am looking to get the S6 this spring in the waterproof version, if there is one. Will also get a 128GB card. I have about 25 full length movies on my card, along with almost every episode of Seinfeld and Deadwood.
Oh, that’s yet another thing that you can do with a Samsung but cannot with an Apple.....expand the memory.
I’ve had mine for 5 months and I love it. The battery life surprised me. I couldn’t live without my Swype feature. My friends with iPhones tried to download the app when I first got it on my previous phone, but they were informed that Apple doesn’t have such a feature. Not sure if that’s still true, but my Swype feature is better than ever on my new Galaxy S5.
I got the Note 4 in November. Absolutely love it. It is so light, speedy. Put a 64 GB card in it. Haven’t made a dent in the storage capacity I have available.
