An infrared proximity sensor Optical proximity sensor in a 2016 Samsung smartphone.A proximity sensor is a standard feature of most smartphones, disabling the touchscreen when positioned near an ear during phone calls; more recent (late 2019-early 2020) smartphones with OLED displays may have the sensor mounted under the display.
The technology enables smartphones, tablets and other devices to perform actions when in close proximity to a beacon. Bluetooth beacons use Bluetooth Low Energy proximity sensing to transmit a universally unique identifier [ 1 ] picked up by a compatible app or operating system.
Smartphone detecting an iBeacon transmitter. iBeacon is a protocol developed by Apple and introduced at the Apple Worldwide Developers Conference in 2013. [1] Various vendors have since made iBeacon-compatible hardware transmitters – typically called beacons – a class of Bluetooth Low Energy (BLE) devices that broadcast their identifier to nearby portable electronic devices.

The iPhone's proximity sensors detect the ear and switches off the light, saving power and stopping the face from unintentionally pressing buttons. A phone case, dirt or grime, or a software problem may cause the proximity sensor to malfunction.
This is a list of smartphones with a primary camera that uses a 1.0-type (“1-inch”) image sensor or larger. However, as of February 2024, there are no smartphones that use a sensor larger than 1.0-type. The first camera phone to feature a 1.0-type sensor was the Panasonic Lumix CM1 in 2014. Seven years passed before another phone featured ...
Like other proximity card technologies, NFC is based on inductive coupling between two electromagnetic coils present on a NFC-enabled device such as a smartphone. NFC communicating in one or both directions uses a frequency of 13.56 MHz in the globally available unlicensed radio frequency ISM band , compliant with the ISO/IEC 18000-3 air ...
A multifunction sleep wake button is located on the top of the device, which serves as the unit's power and sleep button and also controls phone calls. The device responds to four sensors. A proximity sensor deactivates the display and touchscreen when the device is brought near the face during a call. This is done to save battery power and to ...
