On the iPhone 7, Apple replaced the mechanical home button and added the latest Taptic Engine vibrator to this button. The exterior looks the same, but the internal technical content is quite different. Below the glass button is the tactile feedback device of Taptic Engine, which can realize different functions through finger touch. Taptic Engine is an exclusive vibrator developed by Apple. Unlike the rotor vibration motor of a conventional mobile phone, richer feedback can be achieved by different pressing. On Apple Watch, the main function of Taptic Engine is tactile feedback, just like someone knocks on your wrist.
The original camera of iPhone 7 has been upgraded. The optical module became 6 pieces of glass, and the aperture changed from? /2.2 Increase to? /1.8, increasing the light input by 50%, changing the number of flash lamps from 2 to 4, and both one large and one small mobile phones support optical image stabilization; The front lens is upgraded from 5 million pixels to 7 million pixels; The true color tone on the back is changed from double LEDs to four LEDs, which doubles the brightness and can still be adjusted according to the ambient color temperature, making the skin color more natural in dark light.
The screen size and resolution have not changed, but the screen brightness has been upgraded to 625cd/m2 (previously 500), which will be clearer in strong sunlight; In addition, more importantly, the color performance is better. The full sRGB standard used for many years on iPhone has been upgraded to DCI-P3 wide color gamut.
IPhone 7 supports IP67 waterproof (1 meter deep without flowing clear water), adopts polymer coating, and USB bareheaded exposed interface is waterproof, which ensures the unity of appearance and practicality to the greatest extent. The layout design of the sensor and flash hole remains unchanged, the camera is highlighted, and the printed antenna is exposed, but the position is moved to the top and bottom of the fuselage.
The iPhone 7 continues the Scandinavian design style of pursuing simplicity in the iPhone 6 period. It maintains a fairly simple positive look and feel, and at the same time, it has a relatively rounded border to take care of the grip.
