The screen size, slightly larger than my S3, is a plus. The Android version is crisp. Sound quality is good.
I only have 2 disappointments: 1) the USB 3,0 cable for charging is difficult to get into the port (and I use USB 3.0 on a lot of devices, so this is not a user training issue), and 2) I have yet to find a way to balance the screen lighting to make it visible in bright sunlight ... it is great everywhere else.
This phone is fast, battery is incredible. Features are amazing especially the battery extender. The only negative thing I could say is the plastic back is cheap cheap cheap. It had cracked at 2 months of owning and best buy would nor replace and that is even being in aq body glove case. The battery pet cover broke as well. Other than those things it is amazing.
Is very fast in the menus and taken pictures, the quality of photos is great. The width is fantastic. The battery life most be enhance. Is a great product
I've run through several cells over the years but the S5 wit KitKat is the best so far. I can see it in daylight, it works well with my Pebble, it's waterproof (which you don't want to need but may). Just the right size - any larger and it wouldn't work for men who put them into their front pockets. Overall just right.
