After struggling hard to get back on its feet after losing little by little to iPhone series, the Galaxy maker Samsung is back again with the all new Galaxy S6. This device which surpasses the olden Galaxy S4 launched 2 years back after failing woefully as a result of no improvement from the earlier device the successful Galaxy S3.
We all knew that and not because Samsung likely lied about the fantasy “Eye scrolling” and ” Air swipe” which we didn’t really have much opportunity to see function as it was echoed all around the world. But better still, the company proves it’s worth ones again with the might device.
Although the overall design of the Galaxy S6 still features some similarities to prior models, the construction of the device itself was revamped, with a metal unibody frame and glass backing instead of plastic. The devices also introduced an improved camera, a streamlined user interface, support for both major wireless charging standards, and support for a mobile payments platform that allows the device to emulate themagnetic stripfrom a creditcard. The S6 features other hardware improvements as well, including a1440pdisplay, a new in-house system-on-chip that utilizes a14 nm Fin FET manufacturing process, and an improved fingerprint scanner. The Galaxy S6 and S6 Edge received mostly positive reviews from critics, who praised the devices’ upgraded build quality over prior models, along with improvements to their displays, performance, camera, and other changes. However, Samsung’s decision to remove the ability to expand their storage or remove the battery was panned as being potentially alienating to power users, and the S6 Edge was also panned for not making enough use of its curved display to justify its increased cost over the standard Samsung Galaxy S6.
Released on the 10th of April 2015, the phone had been a closer rival ever since with the IPhone 6 and 6plus devices.
