The arrival of the S6 and S6 Edge has finally spelled the end of the Galaxy S3. The Galaxy S4 comes in at 136.6 x 69.8 x 7.9mm, the same dimensions as the S3, meaning it feels pretty tiny in the hand compared with todays super-sized smartphones.
Samsung usually excels with its screens, and the S4 offers a 5-inch display with Full HD resolution. Thats no longer a big deal when compared to the QHD offerings of todays top handsets( such as the 5.5-inch LG G3) but its still good enough for the likes of the HTC One M9.
I should also note that the Galaxy S4 is considerably smaller and lighter than its successor, the Galaxy S5, despite conceding a mere 0.1 of an inch in screen size. This is evidently a result of the S5s tougher water and dust-resistant construction, but not everyone will count this as a worthwhile compromise.
The Galaxy S4 shares a lot with the other top smartphones of its era. Both the Sony Xperia Z1 and the HTC One have screens that use the same resolution, but neither of them have the still impressive clout of the Super AMOLED HD screen on offer her
