Samsung’s New Feature in Android 15: Tapping the Back of Your Phone to Check Time

In a groundbreaking move, Samsung has announced its latest innovation for the upcoming Android 15. This new feature, named “Back Tap Check Time,” allows users to check the current time simply by double-tapping the back of their Samsung smartphones. This new functionality, available for select models, is designed to cater to the increasing demand for convenience and ease-of-use in our daily lives.

How It Works

To enable this feature, users need to navigate to the “Motion and Gestures” settings within their phone’s “Accessibility” menu. Once activated, they can customize their double-tap gesture to display the time whenever they tap the back of their phone twice.

Implications and Benefits

This feature has significant implications for productivity and accessibility. Users can now quickly check the time without having to unlock their phones or even look at them, making it ideal for situations where they need to keep one hand free. Furthermore, individuals with motor disabilities may find this feature particularly beneficial, as it allows them to access the time using a simple tap gesture.

Security Concerns and Privacy

As with any new feature, concerns around security and privacy arise. Double-tapping the back of a phone could potentially register as unintentional touches, leading to unwanted app opens or accidental input. However, Samsung has addressed these concerns by implementing a confirmation prompt when the feature is first enabled and allowing users to adjust the sensitivity of the double-tap gesture. Additionally, no user data is shared or recorded in conjunction with this feature.


Samsung’s “Back Tap Check Time” is a testament to the company’s commitment to innovation and user experience. By allowing users to check the time with a simple tap on the back of their phone, Samsung is making interactions more convenient and accessible than ever before while maintaining a strong focus on privacy and security. This new feature is yet another reminder that technology is constantly evolving to meet our needs and make our lives easier.

Understanding the Technology Behind the Feature

Use of Ultrasonic Sensors

Explanation of ultrasonic technology: Ultrasonic sensors are a type of proximity sensor that use high-frequency sound waves to detect objects and distances. They emit ultrasonic pulses and listen for the echoes that bounce back off nearby surfaces. This technology is not new, but its application in smartphones for recognizing taps on the back of the phone is a recent innovation.

How it works in this feature: Samsung’s ultrasonic sensor technology, called “S Pen Input,” uses the sensor to detect the presence and location of the S Pen on the back of the Galaxy Note series phones. When you tap the pen on the phone, the ultrasonic sensor emits a short burst of sound waves and listens for the echo to determine the exact location and force of the tap.

Role of Accelerometers and Gyroscopes

Description of these sensors: Accelerometers and gyroscopes are both types of motion sensors that help a device understand its orientation and movements in space. An accelerometer measures the linear acceleration of an object, while a gyroscope measures rotational velocity and angle changes.

Function in detecting taps and orientation changes: In the context of Samsung’s smartphone features, these sensors work together to help recognize screen taps and swipes even when the phone is not in your hand. They provide data on the phone’s orientation and movement, which can be used to simulate taps or swipes when the phone is placed face-down on a surface.

Integration with Android OS

Overview of Android 15: Android 15 is the latest version of Google’s mobile operating system, featuring various enhancements and optimizations to improve user experience. It includes new features like improved gestures recognition, enhanced privacy settings, and optimized battery usage.

How the feature is integrated into the operating system: Samsung’s ultrasonic sensor technology and its integration with Android 15 allow for more advanced use cases, like using the S Pen as a remote controller or to navigate through menus. The OS interprets the sensor data and translates it into on-screen actions, providing a more seamless user experience.

Power Consumption and Efficiency Considerations

Discussion on how Samsung minimizes power usage with this feature: Samsung’s implementation of ultrasonic sensors and motion sensors for input recognition is designed to minimize power consumption. The sensors are only active when needed, and the system uses intelligent algorithms to optimize sensor usage based on user behavior.

Comparison to other smartphone manufacturers’ similar features: While some competitors use capacitive or infrared sensors for back-of-phone input recognition, Samsung’s ultrasonic technology offers better accuracy and resistance to external interference. Additionally, the integration with Android 15 ensures efficient power usage, making Samsung’s implementation a significant advancement in this area.
