Fingerprint (Under Display, Optical): This refers to an under-display fingerprint sensor that uses optical technology. Optical fingerprint sensors capture an image of your fingerprint by taking a picture of it using light. They are typically located under the phone's display, allowing you to unlock the device by placing your finger on or near the designated area on the screen. Accelerometer: An accelerometer is a sensor that measures the acceleration of a device. It can detect changes in the device's orientation and movement, which is useful for various applications such as screen rotation, gaming, and fitness tracking. Gyro (Gyroscope): A gyroscope is a sensor that measures the device's orientation and angular velocity. It helps the device understand how it's rotating or moving in space. Gyroscopes are crucial for applications like augmented reality (AR) and virtual reality (VR). Proximity: A proximity sensor detects the presence or absence of an object near the device. This is often used to turn off the screen during phone calls when the device is held to your ear, preventing accidental touches on the touchscreen. Compass: A compass sensor, also known as a magnetometer, detects the device's orientation relative to the Earth's magnetic field. This sensor is used for navigation and location-based applications, providing information about the direction the device is facing. These features are typical in modern smartphones and contribute to various functions and capabilities, including security, motion sensing, and improved user experiences in gaming, navigation, and augmented reality applications.
