No doubt samsung provide their best in inventing flagship phones. Perfection in galaxy S5 is on peak. I use my friends S5 more than 15 days.
Big screen with 3 gb ram performs very well in gaming and other tasks. Battery bacup is averafe but good. Design is very crafty but not stylish. Features like heart rate monitoring make them a unique phone.
However it is complete package with big qualcomm processor. I bet you can easily fall in love in first use.
So buy this phone from amazon and keep travel in this tech era.
