Design

The size of the screen (measured diagonally).
Display type

OLED/AMOLED

The type of technology used in the display.
The device is dustproof and water-resistant. Water-resistant devices can resist the penetration of water, such as powerful water jets, but not being submerged into water.
The first number of the IP rating refers to protection against dust, while the second number refers to protection against liquid. E.g. a first number of 6 denotes that it is completely dustproof, and a second number of 7 denotes that the device can withstand full immersion in water.
The ATM rating indicates how much water pressure a device can withstand. 3 ATM is one of the lowest ratings and means that the device can only withstand splashes of water, whereas 20 ATM is one of the highest ratings and means that the device can be used for snorkeling and water sports.
pixel density

Unknown. Help us by suggesting a value.

Pixel density is a measurement of a screen's resolution, expressed as the number of pixels per inch (PPI) on the screen. A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience.
resolution

Unknown. Help us by suggesting a value.

Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.
refresh rate

Unknown. Help us by suggesting a value.

The frequency at which the display is refreshed (1 Hz = once per second). A higher refresh rate results in smoother UI animations and video playback.
