My cousin is using this phone for over a month. It feels very solid in hand and the soft plastic at the back gives better grip on the handset. The fingerprint scanner security is good if no other family member touches your phone, otherwise it will be matter of tussle.
The quality of the speaker is a very decent and produces a pretty clear sound. It boasts a high-definition display so the colors are very vibrant and crunchy with a lot of contrast, great viewing angles and brightness. With the high-end specs it gives a very smooth and snappy performance.
The S5 performs as smooth as expected from it even on games. Its camera includes a plethora of settings suitable for shooting at different conditions. The photos look very colorful, sharp and vibrant and it does a great job with sharpness and details. In low light photos loose a lot of quality they look very grainy and noisy.
