I probably don't use this phone to its fullest capability but I'm always finding out new things it can do. It's easy to use and navigate and reacts quick to inputs. The size of the screen is awesome. I only wish it could use the s pen. I like the fact that even without an additional case, it will be fine if i accidentally jump into the water with it in my pocket. I did end up buying the Otterbox Preserver (which is awesome) because I have a habit of dropping my phone and I take it with me when I go paddleboarding in the ocean. I trust the phone would be fine in fresh water but I don't trust the saltwater since the headphone jack is open. I haven't found anything that I don't like about the phone yet either. All in all, it's a smart smartphone that does what it is supposed to do.
The Samsung Galazy S5 is a good highly featured phone. The battery last 2 to 3 days with moderate use. The phone connects well to memorized WiFi sources and the bluetooth works well. The only design flaw is the external "Home" button at the bottom of the screen. While a good idea, it constantly turns the phone on when you have it in a pocket and if you accidentially touch it when retrieving a ringing phone from your pocket, it hangs up the incoming call. Rethink that one Samsung.
I am a 76 year old male who does not have great computer skills so some of the actions that are supposed to be intuitive are not obvious. I think the instruction manual should be more inclusive. Also, I think the contacts section should include an address as well as telephone number.
