Samsung unveiled its flagship smartphone Galaxy S6 and S6 Edge at the Mobile World Congress in a hush-hush event. The Korean mobile maker has pinned quite high expectations on the two phones as the sales and share in the market of Samsung mobiles have drastically come down over the last one year or so.  Design wise, Samsung has made some major changes, replacing glass with metal for the body. The front and back of the phone is made with glass and the quality looks premium than before.
 
Both S6 and S6 Edge were developed from the project Zero and for the first time, Samsung has excluded the option of expansion of memory and removable battery.
