Electronics unveiled its flagship smartphone, Galaxy S5 in February after months of speculations, but it disappointed many as most of the rumoured features were not seen in the device. However, the smartphone received mixed reaction from critics after its release on Friday with some describing it as "Samsung's best phone" while others think it's "boring."

The device received a rating of four and a half out of five from CNet. "It (Samsung Galaxy S5) looks good, it performs very well, and it has everything you need to become a fixture in nearly every aspect of your life. But, like a candidate running for reelection, the GS5 gets where it is today based on experience and wisdom, not on flashy features or massive innovation," wrote CNet in its review.

"With the exception of a few nonessential hardware and software additions - like the fingerprint scanner and novel heart-rate monitor - and a few design tweaks, you're pretty much looking at the same phone Samsung released in 2013. The S5 is more of a Galaxy S4 Plus than it is a slam-the-brakes, next-generation device; it makes everything just a little smoother and faster."
