I had the G3 and really liked it but the G5 is even better! I had the option to get a G6 but I'm one of those people that likes access to the battery and the option for expandable memory which I now have with a micro sd. It's a pretty phone. I like the feel of it in my hand. Not too big not too small. The larger screen is so crisp and vibrant it's easy to enjoy viewing videos and pictures. And by the way, this thing takes AMAZING pictures and has some really cool camera features. I would DEFINITELY recommend the Samsung Galaxy S5 to ALL my friends!
Samsung allows you to customize your phone the way you want. It's waterproof and has many, many features, including being able to multitask, LED indicator, and amazing.
