The giant South Korean Samsung company plans to launch two,different-sized models of its smartphone Galaxy S8, while reports assert that the new phone will add more weight, which will make other phones on the market look smaller.The latest speculation suggests that the South Korean firm will launch a 6.2-inch version of the S8, which will be called the Galaxy S8 Plus. The smaller S8, meanwhile, will feature a screen measuring 5.8 inches.
For comparison, the ill-fated Note 7 – Samsung’s flagship large-screened handset before it was recalled and discontinued – used a 5.7-inch display, and last year’s S7 and S7 Edge used a 5.1-inch screen and 5.5-inch screen, respectively.
The iPhone 7 Plus, Apple's largest smartphone, has a 5.5-inch display.
One of the reasons behind Samsung’s seemingly super-size approach is the Galaxy S line’s striking new design.
The S8 is expected to feature a dual-edge curved “infinity display”, which is said to cover 83% of the handset’s front panel. 
That should help the company keep the new handsets relatively compact, but most users will still struggle to reach all areas of those screens with one hand.
