Proximity Sensor Test

Proximity Sensor Test for Android

Description

This app allows you to test the Proximity Sensor - the proximity sensor is located on the upper front part of the phone (usually above the display).
The proximity sensor is usually used to determine how far away a person's head is from the face of a handset device (for example, when a user is making or receiving a phone call). Most proximity sensors return the absolute distance, in cm, to this app but some return only two values, near and far - in this app these two values are respectively processed as "near position" and "far position".
To test the Proximity Sensor, move your hand (or your finger) over it, the frame color should change from red ("far position") to green ("near position") or vice-versa, whenever your hand (or your finger) comes closed to (or is moved away from) proximity sensor.
If there is no red or green border, then one of the following cases is true:

the proximity sensor is not available on this device;
the proximity sensor exists but it is malfunctioning;
the proximity sensor does not exist but the Operative System detects it anyway;
the proximity sensor provides Operative System with wrong values/parameters.

If you notice that the proximity sensor does not properly work, it must be calibrated. Contact your phone manufacturer or search on Internet for more details on how to perform a proximity sensor calibration. Keep in mind, however, that it may not be possible to perform a sensor calibration.
The proximity sensor may not work as intended in the following cases:

If your device has a screen protection film, make sure it is specifically intended for your device. It is important that the protective film does not cover the proximity sensor.
Make sure the proximity sensor is clean.
If you use a case or cover which is not well suited to the phone, it may impact the functionality of the proximity sensor. The case may cover the proximity sensor.
There may be other causes for the proximity sensor not working as intended. In this case, contact the phone manufacturer's support service in order to ask for a solution or even for a phone replacement.

Important Notice

September 10, 2024 : Version 1.13 of this app is the latest version that supports Android KitKat (Android 4.4).
Since the percentage of users still using Android KitKat (Android 4.4) is below 0.5 percent but mainly since a good part of this app requires the AndroidX libraries (which since April 2024 require at least Android 5.0 Lollipop), the next version of this app will no longer be compatible with Android KitKat (minimum supported version will be Android Lollipop 5.0).
However, the latest versions of all apps still compatible with Android KitKat will remain available on the author's website.
This takes place one year after Google's post "Google Play services discontinuing updates for KitKat (API levels 19 & 20) starting August 2023" which claimed that KitKat would no longer be compatible with Google services (Google Play Services).

July 24, 2023 : Today, Google has released a post on his Blog dedicated to developers which claims that Android Kitkat (Android 4.4) will no longer be compatible with Google services (Google Play Services) as of August 2023. As happened with Android Jelly Bean (see previous paragraph), this occurs due to the low percentage of users who still use the above-mentioned Android version (percentage less than 1 percent).
The Author of this app will try to keep compatibility with Android Kitkat, at least until users request it and until Google provides developers with the ability to properly support the above-mentioned Android version.

June 24, 2023 : Version 1.9 of this app is the latest version that supports Android Jelly Bean (Android 4.1, 4.2 and 4.3).
Since the percentage of users still using Android Jelly Bean (Android 4.1, 4.2 and 4.3) is below 0.5 percent, the next version of this app will no longer be compatible with Android Jelly Bean (minimum supported version will be Android Kitkat 4.4).
For the author of this app it is impossible to follow 17 Android versions (from 4.1 to 13), this will allow the author to focus on "only" 14 Android versions, which will become 15 this year with the release of Android 14.
However, the latest versions of all apps still compatible with Android Jelly Bean will remain available on the author's website.
This takes place two years after Google's post "Google Play services discontinuing updates for Jelly Bean" which claimed that Jelly Bean would no longer be compatible with Google services (Google Play Services).

May 19, 2022 : The year 2022 will be a very difficult year for all Android developers. Google has published a policy page that all Android developers will have to respect, which includes the inability to install external APK packages (some well-known File Managers no longer allow this), the inability to access the user's location (and therefore also to GPS), stricter regulations on data security and privacy regulations, increasingly limits to access to device files, an increasingly restricted use of authorizations, up to accessibility restrictions. For no-profit programmers like me, who release free apps, it will be more and more a real risk to continue publishing on the Google Store. For this reason I carry on my apps especially on my personal website, in this case I have more control of the apps I publish, moreover these apps can be updated within the apps themselves (assuming that users may still find a file manager on the Google Store ready to install the APK file provided by me on my website for the first time).
