How to configure, enable or disable the proximity sensor Android. Answers on questions. What is Proximity Sensor Android?
The proximity sensor is a small element of the device that is activated when the phone physically comes close to an object.
Due to the correct operation of the proximity sensor during a conversation, the smartphone display turns off automatically as soon as the user brings it to the ear.
The proximity sensor Android is very useful and even necessary for at least two reasons, namely:
With the screen off during a call, you definitely won’t accidentally press any button on the touch screen, for example, with your ear or cheek.
The proximity sensor is located at the top of the smartphone. As a rule, it is placed next to the front camera lens. On some devices, the sensor is visible to the naked eye, and on some it is not so easy to detect it. To locate the proximity sensor, simply remove the device from your ear during a call and bring your finger to the place next to the front camera. If the display is blank, it means that you have found the sensor.

Features of using the function in different techniques
In household automation, the proximity recognition function is also very widespread. Non-contact sensors are used to turn on table lamps, open water supply taps when a human hand is in their field of action; the displays of refrigerators and microwave ovens will be inactive until the user’s hand approaches them. Equipped with this function and new home automation systems. Touchscreen displays used to control home appliances and lighting are configured to serve as digital frames. But as soon as one of the people approaches them, control buttons immediately appear. A rather interesting technology is the proximity sensor in the phone. What it is, will help to understand the description of the method by which recognition occurs.
Successive approximation method
In this case, the switched capacitive circuit is charged. From this capacitor, a voltage is supplied to the comparator through a low-pass filter, where it is compared with a reference voltage. The counter, synchronized with the generator, is locked by the output of the comparator. It is this signal that is processed for a specific sensor status. The successive approximation method requires a negligible number of external components. In this case, the operation of the circuit is not affected by crosstalk on the supply circuit.
Proximity sensor in the phone. What is it? Mobile phones
Many modern electronics products are equipped with sensors that detect the proximity of an object, such as a finger, to a keyboard or a person’s ear to a telephone. This technology is actively used in all kinds of touch panels, which eliminates mechanical switching of devices, as well as extends their service life. And many may well have a question: the proximity sensor in the phone. What is it and how does it work? Next, this device will be considered from the point of view of implementation by capacitive technology.
Proximity recognition using non-contact technology quickly found application in the field of portable devices that are self-powered. The function is actively used in the latest models of smartphones and tablets, in music players. Its main purpose is to improve the reliability of devices and save electrical energy.
The display of the device will remain inactive until the proximity of the user’s hand is detected, and this is what the proximity sensor in the phone is responsible for. What is it. It will become clear if we consider the principle of its operation. When it comes to using this technology, it is worth noting that in standby mode, only the central processor deals with energy consumption. And when proximity sensors detect the proximity of the palm or finger, the display turns on, which displays the current information. All this allows you to reduce the average power consumption of the gadget, while increasing the battery life.
Lock Screen iPhone 4
The proximity sensor works in such a way that it allows you to turn off the smartphone screen during a call to prevent accidental key presses. There are special applications that allow you to lock the screen by simply swiping your hand over it. To turn it on, you need to press the hardware key.
Capacity change detection
How accurately and reliably the proximity sensor will work depends entirely on the accuracy of measurements of the changed capacity of the system. For this purpose, a number of methods have been developed, among which the most famous are charge transfer, successive approximation, capacitance interaction and the sigma-delta method. Two of them are most commonly used. Both use a switched capacitive circuit and an external measuring capacitor.
This is a cliché in the world of smartphones, because it is after a reboot that users get rid of problems. This solution is suitable if the diagnostic program showed that the matter is in a system failure.
Follow the steps in the following sequence:
Press the “Power” button and hold it for a few seconds. Location may vary depending on model.
If the cause of the malfunction is a system failure, then after rebooting the smartphone will work normally.
