Proximity Sensor Test for Android


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:
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:

Important Notice

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).
