A new standard for system animations has been introduced, which improves the app start speed and ensures smooth operating processes. The Mate 20 uses a 6.53in (166mm) 18.7:9 1080p LCD display, while the Mate 20 Pro uses a 6.39in (162mm) 19.5:9 1440p display with curved edges. Both displays contain notches, with the Mate 20 featuring a "teardrop" shape, and the Mate 20 Pro containing a larger tab concealing additional infrared sensors used for a face recognition system. [5] The Mate 20 Pro includes an optical in-screen fingerprint reader. [6] The Mate 20 uses a physical fingerprint sensor on the rear below the cameras instead. Mate 20 Pro model support Qi inductive charging, including "reverse" charging of other Qi-compatible devices from its own battery power. [3] [2] [7] For storage expansion, the Mate 20 utilises a new, proprietary memory card format known as Nano Memory rather than MicroSD, which exactly matches the dimensions of a Nano-SIM card. As such, the devices utilise a hybrid SIM tray where the second slot can be used for either expanded storage or a second SIM card. [8]
The SAR body rating shows the maximum level of exposure to electromagnetic radiation when the device is positioned against the body at the hip. The highest SAR value of mobile devices allowed in the US is set to 1.6 W/kg per 1 g of tissue. It is specified by the FCC and the CTIA follows whether the mobile devices comply with this standard. Silent mode will be enabled by default for notifications from instant messaging apps if you disabled sound and vibration alerts for them before installing this update. The alert mode can be modified in the app settings according to your preferences.a b c d McLellan, Charles. "Huawei Mate 20 and 20 Pro unveiled: More AI, better cameras, wireless charging". ZDNet . Retrieved 2019-02-13. The aperture (f-stop number) indicates the size of the lens diaphragm opening, which controls the amount of light reaching the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening.
GPS (L1 + L5 dual band) / AGPS / Glonass / BeiDou / Galileo (E1 + E5a dual band) / QZSS (L1 + L5 dual band) This special feature allows your devices to work together so that you can get the most out of them. You can mirror the phone on the laptop screen and be more productive with multiple app windows that are always available. (A Huawei laptop with PC Manager version 11.0 or higher is required for this function.)Projection ] When you project your phone to an external display in Do Not Disturb mode, messages and incoming calls are only shown on the phone screen. This protects your data and avoids interruption of the screen projection. Focal length is the distance in millimeters from the focal point of the image sensor to the optical center of the lens. The 35 mm equivalent indicates the focal length at which a full-frame camera will achieve an angle of view that's the same as the one of the camera of the mobile device. It is measured by multiplying the native focal length of the camera by the crop factor of the sensor. The crop factor itself can be determined as the ratio between the diagonal distances of the image sensor in the 35 mm camera and a given sensor. Front camera Modern smartphones have one or more front cameras and their positioning has led to various design concepts – pop-up camera, rotating camera, notch, punch hole, under-display camera, etc. Sensor type
