5 Ways The BlackBerry Z30 Is Not The Samsung Galaxy S4

LCD Screen

Both devices are built around 5-inch super active-matrix organic light-emitting diode (AMOLED). The "super" part just means that it's brighter and contains more pixels than regular AMOLED. In Samsung's case, it's a lot more. Resolution of the Z30 is 1,280 x 720, which calculates to 295 pixels per inch. And while the BlackBerry screen actually looks quite sharp and is plenty bright enough, it's practically blurry next to Samsung's. The Galaxy S4 faces the world with a full HD display -- 1,920-x-1,080 pixels. That's a whopping 441 ppi. Both offer multitouch capability, have proximity sensors and automatically adjust brightness based on ambient lighting conditions.
